Introduction

As part of our coursework fulfillment for the subject Microprocessor (INB 22603),

we are conducting a lab project assignment. The project was supposed to make sound

output based on an input sensor detected from a vibrating or pressure. It’s like the same

thing as alarm system that being used for the houses as a security purpose. The main

objective of this project is to learn on how to implement the input sensor to make the

sound as an output.

Brief Explanation on Previous Work.

Our project planned was inspired by a project that we found on Youtube that

published on Aug 12, 2012. That project have been done by Lucas Zanella which is a

person that work in developing applications with AIR technology integrated with PHP

and MySQL, and also Python. He also has a corporation (Zanella Corp) where his

applications were hosted. As he stated, his project had been made with arduino (the

microcontroller), transistors for body signal amplification and an arduino-to-flash

communication interface programmed by him. The arduino reads the keys pressed,

sends it to the his macbook that running a flash application which load the right pack OS

sounds and plays it.

The project called as “Paper piano with arduino” inspired us so much that we

would like to do slightly the same as the “Paper piano with arduino” type of project. This

is because the “Paper piano with arduino” project has been our interest to learn more on

how to implement the project using a microcontroller. Furthermore we can learn from

this project basically on how the operation works and to know what operation that needs

to be done to produce the sound using the microcontroller. We also can learn on how to

apply microcontroller in the operation which is when the sensor input that we apply

detects vibration or pressure, the microcontroller automatically will triggered and

produce the sound as and output.

Project Methodology

Step 1: Plan

Identify and understand on how to use the microcontroller and other component

or requirement to complete this project

Complete the project plans

Step 2: Architecture & Design

Design or create the base of the input sensor so that the input sensor can sense

the pressure or vibration

Step 3: Develop

Construct the circuit and microcontroller

From the input sensor, apply it to the circuit

From the circuit, we need to program to produce different type of sound using

computer

Speaker for the output to produce sound

Step 4: Test

Execute and test the project
