Why this project?The main occupation in our country that contributes to the economy is agriculture. We need to support of our farmers both economically and resource them with modern technology.In the current scenario of our country, the life of farmers in the villages is miserable due to the uncertainty of power supply.

Our farmers are DYING !!Especially in southern India where the main source of farmers is agriculture and that is dependent on the power supply which is uncertain due to the irregular monsoon rainfall.Hence, we as engineers need to devise technology that is useful for real time applications and is also of some use to the society.So we would design a motor, whose operation/running time can be given as input by the keypad and the motor operates for that time. Even in the event of power failure it records the time and resumes it at the supply of power.

Arduino Mega

It consists of 54 digital pins and 16 analog pins and is capable of multiple channel communication.It uses an ATMEGA 2560 chip as an IC.It is the next version of Arduino UNO

SOLAR PANELHere we use a 10W solar panel with the following specificationsVoc = 21VI scmax = 0.59A

This solar panel is included in the project since, an RTC shield is not being used here and this panel provides an input to power up the Arduino mega.

TRIAC SHIELDIt is used to control the AC power supply.It essentially consists of two thyristors connected in anti-parallel direction.

7808 IC 7808 IC is an Ic which belongs to the family of 780x series.It is used essentially as a voltage regulator, which gives a constant 8v output.The pin diagram of 7808 is as follows.We use this to step down to the voltage to 8 volts, to provide input and power up the Arduino mega.

Sequential WorkingThe solar panel is used to give an input to the Arduino mega.The Arduino prompts the user and asks him to give the input.After giving the inputs, the Arduino starts and works as a countdown timer and switches the load on (pulse up the triac shield) and upon completion of the time; it switches off the load and resets itself for the next cycle.

It can also be used for Industrial applications by connecting it with a computer and giving input by the Serial keyboard.The programs for both the applications have been embodied in the documentation. LCD display
