CHAPTER ONE

INTRODUCTION1.1 – Introduction

As the amount of controllable fittings and domestic appliances in the home rises, the ability of these devices to interconnect and communicate with each other digitally becomes a useful and desirable feature. The consolidation of control or monitoring signals from appliances, fittings or basic services is an aim of Home automation.

In simple installations this may be as straightforward as turning on the lights when a person enters the room. In advanced installations, rooms can sense not only the presence of a person inside but know who that person is and perhaps set appropriate lighting, temperature, music levels or television channels, taking into account the day of the week, the time of day, and other factors.

Other automated tasks may include setting the air conditioning to an energy saving setting when the house is unoccupied, and restoring the normal setting when an occupant is about to return. More sophisticated systems can maintain an inventory of products, recording their usage through an RFID tag, and prepare a shopping list or even automatically order replacements.

Home automation can also provide a remote interface to home appliances or the automation system itself, via telephone line, wireless transmission or the internet, to provide control and monitoring via a Smart Phone or Web browser.

An example of a remote monitoring implementation of home automation could be when a smoke detector detects a fire or smoke condition, then all lights in the house will blink to alert any occupants of the house to the possible fire. If the house is equipped with a home theatre, a home automation system can shut down all audio and video components to display the alert or make an audible announcement. The system could also call the home owner on their mobile phone to alert them, or call the fire brigade or alarm monitoring company to bring it to their attention

1.2 – Objectives

the main objective of our project is to make it easy to every one to contact with his/her home and controlling there HWs; without being at home saving there time in an efficiency way.

1.3 - project scope :

Mobile devices are anywhere, these days every one is connected with the world using wireless devices and amazingly mobiles are most commonly used wireless device. Today most of the mobile devices can get connected to the internet and access the web pages. So now a days programmers and designers become to develop a mobile application which is an application that use a set of technologies and specifications developed for small devices like pagers, mobile phones, and BDAs.

Our project is a web application which will be browsed by mobile devices to control different hardware in your home to be turned off or on.

our idea came from developing an old project that was about controlling the hardware by the remote control that was made in our University , so we thought that it will be a good idea to implement it as a new idea in our graduation projects because the mobile become an important part in every one’s life and it can make it easy for every body to accomplish many things by using it.

we implement it by simulating the house hardware using special materials also we are developing a web application, that will be browsed on mobile.

1.4 - Plan of actions :

First of all after we have the idea of our project we analyzed the project by defining the actors, use cases, supplementary, functional requirements, class diagram, data flow diagram, deployment diagram……etc

then we decide what we need to start developing our idea, we started with determining the harewares that we will need then starting to build the hard ware part and testing it. The second step is programming by using visual studio2005 (ASP.Net and C#) to build our web application, after this step we design the web application using simple GUI because our application will be browsed on mobile, and the last step we did was testing our web application.

1.51- Home Control System:

HCS is a web application developed using ASP.net, its aim is to control home devices by PC and mobile, the user request our web application using his/her mobile device then he/she has to login (enter his/her user name and password) after that he can select an item of the menu to control either the home devices or the computer, also he/she can select the camera option from the menu(select camera displaying Snapshoot) to view what is happening inside his/her home.

System Analysis

CHAPTER TWO

System Analysis2.1 – Introduction

Home automation is the residential extension of building automation. It is

automation of the home, housework or household activity. Homeautomation may

include centralized control of lighting, HVAC (heating, ventilation and air

conditioning), appliances, security locks of gates and doors and other systems, to

provide improved convenience, comfort, energy efficiency and security. Home

automation for the elderly and disabled can provide increased quality of life for

persons who might otherwise require caregivers or institutional care.

The popularity of home automation has been increasing greatly in recent years

due to much higher affordability and simplicity through smartphone and tablet

connectivity. The concept of the "Internet of Things" has tied in closely with the

popularization of home automation.

A home automation system integrates electrical devices in a house with each

other. The techniques employed in home automation include those in building

automation as well as the control of domestic activities, such as home

entertainment systems, houseplant and yard watering, pet feeding, changing the

ambiance "scenes" for different events (such as dinners or parties), and the use

of domestic robots. Devices may be connected through a home network to allow

control by a personal computer, and may allow remote access from theinternet.

Through the integration of information technologies with the home environment,

systems and appliances are able to communicatein an integrated manner which

results in convenience, energy efficiency, and safety benefits.

Automated homes of the future have been staple exhibits for World's Fairs and

popular backgrounds in science fiction. However, problems with complexity,

competition between vendors, multiple incompatible standards, and the resulting

expense have limited the penetration of home automation to homes of the

wealthy, or ambitious hobbyists. Possibly the first "home computer" was an

experimental homeautomation

2.2 - Case Study (Legacy System) :

The idea of our system came from an old system which is controlling the house

devices using the remote control so the user can be able to control the devices

only from inside the house .Because of this, we create our system which is

controlling the house devices by using the web application which we can browse

it on the mobile that provide the ability of controlling the house devices from

inside and outside the house

2.3 – System Actors :-

1. PC User: user who browsing the web application on PC and uses it in order to

control home devices .

2. Mobile User: user who browsing web on mobile in order to control home

devices.

2.4 – System Use Cases :

U1: Browsing Web Application: System users browsing the Web application on

PC or on Mobile.

U2: Sign In: the next step after browsing the application, the user has to enter

his/her user name and password.

U3: Choose List Item: after Signing In, user can select an item from list.

U4: Sending Commands to serial: the application will send command (user

choice) to serial .

U5: Sending Commands to server: the application will send command(computer

controlling option) to server .

U6 : Receiving Command: the application will receive command from serial

when unexpected action occurred.

.

U7: Change Password: user can change his login Password.

U8: Sign Out: user can exit from his account and return to the main page.

2.5- Supplementary requirements:

1. The user should use a pc that provide an internet service.

2. The user must install the IIS server .

3. The user who is using our system must have an account in accompany that

provide SMS server.

4. Our system must be able to serve unlimited users.

5. Our web must be able to be browsed by mobile in a suitable and good layout

and interface.

2.6 - System elements

Elements of a home automation system include sensors (such as temperature,

daylight, or motion detection), controllers (such as a general-purpose personal

computer or a dedicated automation controller) and actuators, such as motorized

valves, light switches, motors, and others.

One or more human-machine interface devices are required, so that the residents

of the home can interact with the system for monitoring and control; this may be a

specialized terminal or, increasingly, may be an application running on a smart

phone or tablet computer. Devices may communicate over dedicated wiring, or

over a wired network, or wirelessly using one or more protocols.

Building automation networks developed for institutional or commercial

buildings may be adapted to control in individual residences. A centralized

controller can be used, or multiple intelligent devices can be distributed around

the home

2.7-System benefits :

Home automation refers to the use of computer and information technology to

control home appliances and features (such as windows or lighting). Systems can

range from simple remote control of lighting through to complex computer/micro-

controller based networks with varying degrees of intelligence and automation.

Home automation is adopted for reasons of ease, security and energy efficiency.

In modern construction in industrialized nations, most homes have been wired for

electrical power, telephones, TV outlets (cable or antenna), and a doorbell. Many

household tasks were automated by the development of specialized automated

appliances. For instance, automatic washing machines were developed to reduce

the manual labor of cleaning clothes, and water heaters reduced the labor

necessary for bathing.

As the number of controllable devices in the home rises, interconnection and

communication becomes a useful and desirable feature. For example, a furnace

can send an alert message when it needs cleaning, or a refrigerator when it needs

service. If no one is supposed to be home and the alarm system is set, the home

automation system could call the owner, or the neighbors, or an emergency

number if an intruder is detected.

In simple installations, automation may be as straightforward as turning on the

lights when a person enters the room. In advanced installations, rooms can sense

not only the presence of a person inside but know who that person is and perhaps

set appropriate lighting, temperature, music levels or television channels, taking

into account the day of the week, the time of day, and other factors.

Other automated tasks may include reduced setting of the heating or air

conditioning when the house is unoccupied, and restoring the normal setting when

an occupant is about to return. More sophisticated systems can maintain

an inventory of products, recording their usage through bar codes, or an RFID tag,

and prepare a shopping list or even automatically order replacements.

Home automation can also provide a remote interface to home appliances or the

automation system itself, to provide control and monitoring on

a smartphone or web browser..

Applications And Connections

3.1 Applications

3.1.1- Wi-Fi

Wi-Fi, also spelled Wifi or WiFi, is a technology that allows an electronic device to exchange data or connect to the internet wirelessly using 2.4 GHz UHF and 5 GHz SHF radio waves. The name is a trademark name, and was stated to be a play on the audiophile term Hi-Fi. The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards". However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". Only Wi-Fi products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" trademark.

Many devices can use Wi-Fi, e.g., personal computers, video-game consoles, smartphones, some digital cameras, tablet computers anddigital audio players. These can connect to a network resource such as the Internet via a wireless network access point. Such an access point (or hotspot) has a range of about 20 meters (66 feet) indoors and a greater range outdoors. Hotspot coverage can comprise an area as small as a single room with walls that block radio waves, or as large as many square kilometres achieved by using multiple overlapping access points

Wi-Fi can be less secure than wired connections (such as Ethernet) because an intruder does not need a physical connection. Web pages that use SSL are secure but unencrypted internet access can easily be detected by intruders. Because of this, Wi-Fi has adopted various encryption technologies. The early encryption WEP, proved easy to break. Higher quality protocols (WPA, WPA2) were added later. An optional feature added in 2007, called Wi-Fi Protected Setup (WPS), had a serious flaw that allowed an attacker to recover the router's password.[2] The Wi-Fi Alliance has since updated its test plan and certification program to ensure all newly certified devices resist attacks

Uses

To connect to a Wi-Fi LAN, a computer has to be equipped with a wireless network

interface controller. The combination of computer and interface controller is called

a station. All stations share a single radio frequency communication channel.

Transmissions on this channel are received by all stations within range. The hardware

does not signal the user that the transmission was delivered and is therefore called a best-

effort delivery mechanism. A carrier wave is used to transmit the data in packets, referred

to as "Ethernet frames". Each station is constantly tuned in on the radio frequency

communication channel to pick up available transmissions

Advantages

Wi-Fi allows cheaper deployment of local area networks (LANs). Also spaces where

cables cannot be run, such as outdoor areas and historical buildings, can host wireless

LANs.

Manufacturers are building wireless network adapters into most laptops. The price

of chipsets for Wi-Fi continues to drop, making it an economical networking option

included in even more devices.[citation needed]

Different competitive brands of access points and client network-interfaces can inter-

operate at a basic level of service. Products designated as "Wi-Fi Certified" by the Wi-Fi

Alliance are backwards compatible. Unlike mobile phones, any standard Wi-Fi device

will work anywhere in the world.

Wi-Fi Protected Access encryption (WPA2) is considered secure, provided a

strong passphrase is used. New protocols for quality-of-service (WMM) make Wi-Fi

more suitable for latency-sensitive applications (such as voice and video). Power saving

mechanisms (WMM Power Save) extend battery life

RangeWi-Fi networks have limited range. A typical wireless access point using 802.11b or

802.11g with a stock antenna might have a range of 35 m (115 ft) indoors and 100 m

(330 ft) outdoors. IEEE 802.11n, however, can more than double the range. Range also

varies with frequency band. Wi-Fi in the 2.4 GHz frequency block has slightly better

range than Wi-Fi in the 5 GHz frequency block which is used by 802.11a and optionally

by 802.11n. On wireless routers with detachable antennas, it is possible to improve range

by fitting upgraded antennas which have higher gain in particular directions. Outdoor

ranges can be improved to many kilometers through the use of high gain directional

antennas at the router and remote device(s). In general, the maximum amount of power

that a Wi-Fi device can transmit is limited by local regulations, such as FCC Part 15 in

the US.

Due to reach requirements for wireless LAN applications, Wi-Fi has fairly high power

consumption compared to some other standards. Technologies such

as Bluetooth (designed to support wireless PAN applications) provide a much

shorter propagation range between 1 and 100m and so in general have a lower power

consumption. Other low-power technologies such as ZigBee have fairly long range, but

much lower data rate. The high power consumption of Wi-Fi makes battery life in mobile

devices a concern.

Researchers have developed a number of "no new wires" technologies to provide

alternatives to Wi-Fi for applications in which Wi-Fi's indoor range is not adequate and

where installing new wires (such as CAT-6) is not possible or cost-effective. For

example, the ITU-T G.hn standard for high speed Local area networks uses existing

home wiring (coaxial cables, phone lines and power lines). Although G.hn does not

provide some of the advantages of Wi-Fi (such as mobility or outdoor use), it's designed

for applications (such asIPTV distribution) where indoor range is more important than

mobility.

Due to the complex nature of radio propagation at typical Wi-Fi frequencies, particularly

the effects of signal reflection off trees and buildings, algorithms can only approximately

predict Wi-Fi signal strength for any given area in relation to a transmitter. This effect

does not apply equally to long-range Wi-Fi, since longer links typically operate from

towers that transmit above the surrounding foliage.

The practical range of Wi-Fi essentially confines mobile use to such applications as

inventory-taking machines in warehouses or in retail spaces, barcode-reading devices at

check-out stands, or receiving/shipping stations. Mobile use of Wi-Fi over wider ranges

is limited, for instance, to uses such as in an automobile moving from one hotspot to

another. Other wireless technologies are more suitable for communicating with moving

vehicles

3.1.2- Ethernet

The Arduino Ethernet is a microcontroller board based on the ATmega328 (datasheet). It

has 14 digital input/output pins, 6 analog inputs, a 16 MHz crystal oscillator,

a RJ45 connection, a power jack, an ICSP header, and a reset button.

NB: Pins 10, 11, 12 and 13 are reserved for interfacing with the Ethernet module and

should not be used otherwise. This reduces the number of available pins to 9, with 4

available as PWM outputs.

An optional Power over Ethernet module can be added to the board as well.

http://en.wikipedia.org/wiki/File:Wi-Fi.gif

The Ethernet differs from other boards in that it does not have an onboard USB-to-serial

driver chip, but has a Wiznet Ethernet interface. This is the same interface found on the

Ethernet shield.

An onboard microSD card reader, which can be used to store files for serving over the

network, is accessible through the SD Library. Pin 10 is reserved for the Wiznet

interface, SS for the SD card is on Pin 4.

The 6-pin serial programming header is compatible with the USB Serial adapter and also

with the FTDI USB cables or with Sparkfun and Adafruit FTDI-style basic USB-to-serial

breakout boards. It features support for automatic reset, allowing sketches to be uploaded

without pressing the reset button on the board. When plugged into a USB to Serial

adapter, the Arduino Ethernet is powered from the adapter.

The Revision 3 of the board introduces the standardized 1.0 pinout, that consist in:

added SDA and SCL pins that are near to the AREF pin and two other new pins placed

near to the RESET pin, this will the opportunity to shield that use i2c or TWI components

to be compatible with all the Arduino boards;

the IOREF that allow the shields to adapt to the voltage provided from the board. Shields

that use the IOREF pin will be compatible both with the board that use the AVR, which

operate with 5V and with the Arduino Due that operate with 3.3V. Next to the IOREF pin

there is a not connected pin, that is reserved for future purposes

Power

The board can also be powered via an external power supply, an optional Power over

Ethernet (PoE) module, or by using a FTDI cable/USB Serial connector.

External power can come either from an AC-to-DC adapter (wall-wart) or battery. The

adapter can be connected by plugging a 2.1mm center-positive plug into the board's

power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the

POWER connector.

The board can operate on an external supply of 6 to 20 volts. If supplied with less than

7V, however, the 5V pin may supply less than five volts and the board may be unstable.

If using more than 12V, the voltage regulator may overheat and damage the board. The

recommended range is 7 to 12 volts.

The power pins are as follows:

VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.

5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.

3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.

GND. Ground pins. IOREF. This pin on the Arduino board provides the voltage reference with which the

microcontroller operates. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.

The optional PoE module is designed to extract power from a conventional twisted pair

Category 5 Ethernet cable:

IEEE802.3af compliant Low output ripple and noise (100mVpp) Input voltage range 36V to 57V Overload and short-circuit protection 9V Output High efficiency DC/DC converter: typ 75% @ 50% load 1500V isolation (input to output)

When using the power adapter, power can come either from an AC-to-DC adapter (wall-

wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug

into the board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin

headers of the POWER connector.





Memory

The ATmega328 has 32 KB (with 0.5 KB used for the bootloader). It also has 2 KB of

SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM

library).

Input and Output

Each of the 14 digital pins on the Ethernet board can be used as an input or output,

using pinMode(), digitalWrite(), anddigitalRead() functions. They operate at 5 volts.

Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor

(disconnected by default) of 20-50 kOhms. In addition, some pins have specialized

functions:

Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data. External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low

value, a rising or falling edge, or a change in value. See the attachInterrupt() function for details.

PWM: 3, 5, 6, 9, and 10. Provide 8-bit PWM output with the analogWrite() function. SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication

using the SPI library. LED: 9. There is a built-in LED connected to digital pin 9. When the pin is HIGH value,

the LED is on, when the pin is LOW, it's off. On most other arduino boards, this LED is found on pin 13. It is on pin 9 on the Ethernet board because pin 13 is used as part of the SPI connection.

The Ethernet board has 6 analog inputs, labeled A0 through A5, each of which provide

10 bits of resolution (i.e. 1024 different values). By default they measure from ground to

5 volts, though is it possible to change the upper end of their range using the AREF pin

and the analogReference() function. Additionally, some pins have specialized

functionality:

TWI: A4 (SDA) and A5 (SCL). Support TWI communication using the Wire library.

There are a couple of other pins on the board:

AREF. Reference voltage for the analog inputs. Used with analogReference(). Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset

button to shields which block the one on the board.

Communication

The Arduino Ethernet has a number of facilities for communicating with a computer,

another Arduino, or other microcontrollers.

A SoftwareSerial library allows for serial communication on any of the Uno's digital

pins.

The ATmega328 also supports TWI and SPI communication. The Arduino software

includes a Wire library to simplify use of the TWI bus; see the documentation for details.

For SPI communication, use the SPI library.

The board also can connect to a wired network via ethernet. When connecting to a

network, you will need to provide an IP address and a MAC address. The Ethernet

Library is fully supported.

The onboard microSD card reader is accessible through the SD Library. When working

with this library, SS is on Pin 4.

Programming

It is possible to program the Arduino Ethernet board in two ways: through the 6 pin serial

programming header, or with an external ISP programmer.

The 6-pin serial programming header is compatible with FTDI USB cables and the

Sparkfun and Adafruit FTDI-style basic USB-to-serial breakout boards including the

Arduino USB-Serial connector. It features support for automatic reset, allowing sketches

to be uploaded without pressing the reset button on the board. When plugged into a

FTDI-style USB adapter, the Arduino Ethernet is powered off the adapter.

You can also program the Ethernet board with an external programmer like an AVRISP

mkII or USBTinyISP. To set up your environment for burning a sketch with a

programmer, follow these instructions. This will delete the serial bootloader, however.

All the Ethernet example sketches work as they do with the Ethernet shield. Make sure to

change the network settings for your network.

Physical Characteristics

The maximum length and width of the Ethernet PCB are 2.7 and 2.1 inches respectively,

with the RJ45 connector and power jack extending beyond the former dimension. Four

screw holes allow the board to be attached to a surface or case. Note that the distance

between digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil

spacing of the other pins.

3.2.1- lm35 with Arduino

Figure 3.3: lm35 with arduino

Using the lm35 is easy, simply connect the left pin to power (2.7-5.5V) and the right pin to ground. Then the middle pin will have an analog voltage that is directly proportional (linear) to the temperature. The analog voltage is independant of the power supply.

To convert the voltage to temperature, simply use the basic formula:

Temp in °C = (Vout in mV) / 10

Figure 3.5: relay with arduino

To connect the Relay board to an Arduino is very easy and allows you to turn on

and off an wide range of devices, both AC and DC. The first to connections are the

ground and power pins, You need to connect the Arduino +5 v to the Relay board

VCC pin and the Arduino ground to the Relay board GND pin. Then it's a only a

matter of just connecting the communication pins, labeled IN1, , two 4 data pins on

the Arduino

PROJECT COMPONENTS5.1 Mechanical devices :

1. Ttl camera

This camera module can be a pretty neat project addition. It was designed to be used in

security systems and does two main things - it outputs NTSC monochrome video and can

take snapshots of that video (in color) and transmit them over the TTL serial link. You

can snap pictures at 640x480, 320x240 or 160x120 and they're pre-compressed JPEG

images which makes them nice and small and easy to store on an SD card. Perfect for a

data-logging, security, or photography project.

One nice thing about this particular camera is all the 'extras' that come with it. For

example it has manually adjustable focus, auto-white-balance, auto-brightness and auto-

contrast taken care of for you as well as motion detection built in! That means you can

have it alert your project when something moved in the frame.

We also carry an enclosed weather-proof version Using the module is pretty easy and

only requires two digital pins (or a TTL serial port) - by default it transmits at 38400

baud. Of course we wouldn't just leave you with a datasheet and a 'good luck', we even

spent a lot of time researching the module and DSP to make a really nice Arduino library

with example code that shows how to change the image size and compression quality,

detect motion, control the video output stream, etc. That and more is available in our very

detailed tutorial that will help get the most use out of your camera.

3. Arduino Uno

The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet)

It has 14 digital input/output pins (of which 6 can be used as PWM outputs),6

analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an

ICSP header, and a reset button. It contains everything needed to support the

microcontroller; simply connect it to a computer with a USB cable or power it

with a AC-to-DC adapter or battery to get started.

The Uno differs from all preceding boards in that it does not use the FTDI USB-

to-serial driver chip. Instead, it features the Atmega16U2 (Atmega8U2 up to

version R2) programmed as a USB-to-serial converter.

Revision 2 of the Uno board has a resistor pulling the 8U2 HWB line to ground,

making it easier to put into DFU mode.

Revision 3 of the board has the following new features:

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other

new pins placed near to the RESET pin, the IOREF that allow the shields to

adapt to the voltage provided from the board. In future, shields will be

compatible with both the board that uses the AVR, which operates with 5V

and with the Arduino Due that operates with 3.3V. The second one is a not

connected pin, that is reserved for future purposes.

Stronger RESET circuit.

Atmega 16U2 replace the 8U2.

"Uno" means one in Italian and is named to mark the upcoming release of

Arduino 1.0. The Uno and version 1.0 will be the reference versions of Arduino,

moving forward. The Uno is the latest in a series of USB Arduino boards, and the

reference model for the Arduino platform; for a comparison with previous

versions, see the index of Arduino boards.

Power

The Arduino Uno can be powered via the USB connection or with an external power

supply. The power source is selected automatically.

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or

battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the

board's power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers

of the POWER connector.





The power pins are as follows:

VIN. The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.

5V.This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 - 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don't advise it.

3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.

GND. Ground pins.

IOREF. This pin on the Arduino board provides the voltage reference with which the

microcontroller operates. A properly configured shield can read the IOREF pin voltage

and select the appropriate power source or enable voltage translators on the outputs for

working with the 5V or 3.3V

Memory

The ATmega328 has 32 KB (with 0.5 KB used for the bootloader). It also has 2 KB of

SRAM and 1 KB of EEPROM (which can be read and written with the EEPROM

library).

Input and Output

Each of the 14 digital pins on the Uno can be used as an input or output,

using pinMode(), digitalWrite(), anddigitalRead() functions. They operate at 5 volts.

Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor

(disconnected by default) of 20-50 kOhms. In addition, some pins have specialized

functions:

Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data.

These pins are connected to the corresponding pins of the ATmega8U2 USB-to-TTL

Serial chip.

External Interrupts: 2 and 3. These pins can be configured to trigger an interrupt on a low

value, a rising or falling edge, or a change in value. See the attachInterrupt() function for

details.

PWM: 3, 5, 6, 9, 10, and 11. Provide 8-bit PWM output with the analogWrite() function.

SPI: 10 (SS), 11 (MOSI), 12 (MISO), 13 (SCK). These pins support SPI communication

using the SPI library.

LED: 13. There is a built-in LED connected to digital pin 13. When the pin is HIGH

value, the LED is on, when the pin is LOW, it's off.

The Uno has 6 analog inputs, labeled A0 through A5, each of which provide 10 bits of

resolution (i.e. 1024 different values). By default they measure from ground to 5 volts,

though is it possible to change the upper end of their range using the AREF pin and

the analogReference() function. Additionally, some pins have specialized functionality:

TWI: A4 or SDA pin and A5 or SCL pin. Support TWI communication using the Wire

library.

There are a couple of other pins on the board:

AREF. Reference voltage for the analog inputs. Used with analogReference().

Reset. Bring this line LOW to reset the microcontroller. Typically used to add a reset

button to shields which block the one on the board.

See also the mapping between Arduino pins and ATmega328 ports. The mapping for the

Atmega8, 168, and 328 is identical.

Communication

The Arduino Uno has a number of facilities for communicating with a computer, another

Arduino, or other microcontrollers. The ATmega328 provides UART TTL (5V) serial

communication, which is available on digital pins 0 (RX) and 1 (TX).

An ATmega16U2 on the board channels this serial communication over USB and appears

as a virtual com port to software on the computer. The '16U2 firmware uses the standard

USB COM drivers, and no external driver is needed. However, on Windows, a .inf file is

required. The Arduino software includes a serial monitor which allows simple textual

data to be sent to and from the Arduino board. The RX and TX LEDs on the board will

flash when data is being transmitted via the USB-to-serial chip and USB connection to

the computer (but not for serial communication on pins 0 and 1).

A SoftwareSerial library allows for serial communication on any of the Uno's digital

pins.

The ATmega328 also supports I2C (TWI) and SPI communication. The Arduino

software includes a Wire library to simplify use of the I2C bus; see the documentation for

details. For SPI communication, use the SPI library.

Programming

The Arduino Uno can be programmed with the Arduino software (download). Select

"Arduino Uno from the Tools > Board menu (according to the microcontroller on your

board). For details, see the reference and tutorials.

The ATmega328 on the Arduino Uno comes preburned with a bootloader that allows you

to upload new code to it without the use of an external hardware programmer. It

communicates using the original STK500 protocol (reference, C header files).

You can also bypass the bootloader and program the microcontroller through the ICSP

(In-Circuit Serial Programming) header; see these instructions for details.

The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is

available . The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be

activated by:

On Rev1 boards: connecting the solder jumper on the back of the board (near the map of

Italy) and then resetting the 8U2.

On Rev2 or later boards: there is a resistor that pulling the 8U2/16U2 HWB line to

ground, making it easier to put into DFU mode.

You can then use Atmel's FLIP software (Windows) or the DFU programmer (Mac OS X

and Linux) to load a new firmware. Or you can use the ISP header with an external

programmer (overwriting the DFU bootloader). See this user-contributed tutorial for

more information.

Automatic (Software) Reset

Rather than requiring a physical press of the reset button before an upload, the Arduino

Uno is designed in a way that allows it to be reset by software running on a connected

computer. One of the hardware flow control lines (DTR) of theATmega8U2/16U2 is

connected to the reset line of the ATmega328 via a 100 nanofarad capacitor. When this

line is asserted (taken low), the reset line drops long enough to reset the chip. The

Arduino software uses this capability to allow you to upload code by simply pressing the

upload button in the Arduino environment. This means that the bootloader can have a

shorter timeout, as the lowering of DTR can be well-coordinated with the start of the

upload.

This setup has other implications. When the Uno is connected to either a computer

running Mac OS X or Linux, it resets each time a connection is made to it from software

(via USB). For the following half-second or so, the bootloader is running on the Uno.

While it is programmed to ignore malformed data (i.e. anything besides an upload of new

code), it will intercept the first few bytes of data sent to the board after a connection is

opened. If a sketch running on the board receives one-time configuration or other data

when it first starts, make sure that the software with which it communicates waits a

second after opening the connection and before sending this data.

The Uno contains a trace that can be cut to disable the auto-reset. The pads on either side

of the trace can be soldered together to re-enable it. It's labeled "RESET-EN". You may

also be able to disable the auto-reset by connecting a 110 ohm resistor from 5V to the

reset line; see this forum thread for details.

USB Overcurrent Protection

The Arduino Uno has a resettable polyfuse that protects your computer's USB ports from

shorts and overcurrent. Although most computers provide their own internal protection, the fuse provides an extra layer of protection. If more than 500 mA is applied to the USB port, the fuse will automatically break the connection until the short or overload is removed.

Physical Characteristics

The maximum length and width of the Uno PCB are 2.7 and 2.1 inches respectively, with

the USB connector and power jack extending beyond the former dimension. Four screw

holes allow the board to be attached to a surface or case. Note that the distance between

digital pins 7 and 8 is 160 mil (0.16"), not an even multiple of the 100 mil spacing of the

other pins.

4. Relay

A relay is automatic device which senses an abnormal condition of electrical

circuit and closes its contacts. These contacts in turns close and complete the

circuit breaker trip coil circuit hence make the circuit breaker tripped for

disconnecting the faulty portion of the electrical circuit from rest of the healthy

circuit.

Now let’s have a discussion on some terms related to protective relay

Pickup level of actuating signal: The value of actuating quantity (voltage or

current) which is on threshold above which the relay initiates to be operated.

If the value of actuating quantity is increased, the electro magnetic effect of the

relay coil is increased and above a certain level of actuating quantity the moving

mechanism of the relay just starts to move.

Reset level: The value of current or voltage below which a relay opens its contacts

and comes in original position.

http://arduino.cc/en/uploads/Main/ArduinoUno_R3_Front.jpg

Operating Time of Relay - Just after exceeding pickup level of actuating quantity

the moving mechanism (for example rotating disc) of relay starts moving and it

ultimately close the relay contacts at the end of its journey. The time which

elapses between the instant when actuating quantity exceeds the pickup value to

the instant when the relay contacts close.

Reset time of Relay – The time which elapses between the instant when

the actuating quantity becomes less than the reset value to the instant

when the relay contacts returns to its normal position.

Reach of relay – A distance relay operates whenever the distance seen by

the relay is less than the pre-specified impedance. The actuating

impedance in the relay is the function of distance in a distance protection

relay. This impedance or corresponding distance is called reach of the

relay.

Power system protection relays can be categorized into different Types of relays.

Types of protection relays are mainly based on their characteristic, logic, on

actuating parameter and operation mechanism.

Based on operation mechanism protection relay can be categorized as Electro

Magnetic relay, Static relay and Mechanical relay. Actually relay is nothing but a

combination of one or more open or closed contacts. These all or some specific

contacts the relay change their state when actuating parameters are applied to the

relay. That means open contacts become closed and closed contacts become open.

In electromagnetic relay these closing and opening of relay contacts are done by

electromagnetic action of a solenoid

5. WiFi Shield

OverviewThe Arduino WiFi Shield connects your Arduino to the internet wirelessly.

Connect it to your wireless network by following a few simple instructions to start

controlling your world through the internet. As always with Arduino, every

element of the platform – hardware, software and documentation – is freely

available and open-source. This means you can learn exactly how it's made and

use its design as the starting point for your own circuits.

-Requires an Arduino board (not included)

-Operating voltage 5V (supplied from the Arduino Board)

-Connection via: 802.11b/g networks

-Encryption types: WEP and WPA2 Personal

-Connection with Arduino on SPI port

-on-board micro SD slot

-ICSP headers

-FTDI connection for serial debugging of WiFi shield

-Mini-USB for updating WiFi shield firmware

Description

The Arduino WiFi Shield allows an Arduino board to connect to the internet

using the 802.11 wireless specification (WiFi).

It is based on the HDG104 Wireless LAN 802.11b/g System in-Package. An

Atmega 32UC3 provides a network (IP) stack capable of both TCP and UDP. Use

the WiFI library to write sketches which connect to the internet using the shield.

TheWiFI shield connects to an Arduino board using long wire-wrap headers

which extend through the shield. This keeps the pin layout intact and allows

another shield to be stacked on top.

The WiFi Shield can connect to wireless networks which operate according to the

802.11b and 802.11g specifications.

There is an onboard micro-SD card slot, which can be used to store files for

serving over the network. It is compatible with the Arduino Uno and Mega. The

onboard microSD card reader is accessible through the SD Library. When

working with this library, SS is on Pin 4.

Arduino communicates with both the Wifi shield's processor and SD card using

the SPI bus (through the ICSP header). This is on digital pins 11, 12, and 13 on

the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to

select the HDG104 and pin 4 for the SD card. These pins cannot be used for

general I/O. On the Mega, the hardware SS pin, 53, is not used to select either

the HDG104 or the SD card, but it must be kept as an output or the SPI interface

won't work.

Digital pin 7 is used as a handshake pin between the WiFi shield and the Arduino,

and should not be used

6. LM35

is a precision IC temperature sensor with its output proportional to the

temperature (in oC). The sensor circuitry is sealed and therefore it is not subjected

to oxidation and other processes. With LM35, temperature can be measured more

accurately than with a thermistor. It also possess low self heating and does not

cause more than 0.1 oC temperature rise in still air.

The operating temperature range is from -55°C to 150°C. The output voltage

varies by 10mV in response to every oC rise/fall in ambient temperature, i.e., its

scale factor is 0.01V/ oC.

7. lamp

A lamp is a replaceable component such as an incandescent light bulb, which is

designed to produce light from electricity. These components usually have a base

of ceramic, metal, glass or plastic, which makes an electrical connection in the

socket of a light fixture. This connection may be made with a screw-thread base,

two metal pins, two metal caps or a bayonet cap.

Types

There are several types of lamp:

Incandescent lamp, a heated filament inside a glass envelope

Halogen lamps use a fused quartz envelope, filled with halogen gas

LED lamp, a solid-state lamp that uses light-emitting diodes (LEDs) as

the source of light

Laser diode lamp

Arc lamp

Xenon arc lamp

Mercury-xenon arc lamp

Ultra-high-performance lamp, an ultra-high-pressure mercury-vapor arc

lamp for use in projectors

Metal-halide lamp

Gas-discharge lamp, a light source that generates light by sending

an electrical discharge through an ionized gas

Fluorescent lamp

Compact fluorescent lamp, a fluorescent lamp designed to replace

an incandescent lamp

Neon lamp

Mercury-vapor lamp

Sodium-vapor lamp

Sulfur lamp

Electrodeless lamp, a gas discharge lamp in which the power is

transferred from outside the bulb to inside via electromagnetic fields

Lamp circuit symbol

8. Cd-Rom

is a pre-pressed optical compact disc which contains data. The name is

an acronym which stands for "Compact Disc Read-Only Memory". Computers

can read CD-ROMs, but cannot write on the CD-ROM's which are not writable or

erasable

CD-ROMs are identical in appearance to audio CDs, and data are stored and

retrieved in a very similar manner (only differing from audio CDs in the standards

used to store the data). Discs are made from a 1.2 mm thick disc

of polycarbonate plastic, with a thin layer of aluminium to make a reflective

http://en.wikipedia.org/wiki/File:Lamp_symbol.svg

http://en.wikipedia.org/wiki/File:Lamp_symbol,_old.svg

surface. The most common size of CD-ROM is 120 mm in diameter, though the

smaller Mini CD standard with an 80 mm diameter, as well as numerous non-

standard sizes and shapes (e.g., business card-sized media) are also available.

[citation needed]

Data is stored on the disc as a series of microscopic indentations. A laser is shone

onto the reflective surface of the disc to read the pattern of pits and lands ("pits",

with the gaps between them referred to as "lands"). Because the depth of the pits

is approximately one-quarter to one-sixth of the wavelength of the laser light used

to read the disc, the reflected beam's phase is shifted in relation to the incoming

beam, causing destructive interference and reducing the reflected beam's intensity.

This pattern of changing intensity of the reflected beam is converted into binary

data
