Now a days, technology is spread all around us. We use many gadgets which are a part of technology in our daily routine. This project is generally based on technology in which we control home lightening with our personal computer by sitting around the computer rather than go to a specific room and switch off the lights. We can ON or OFF our home lights by giving commands to our Arduino board which is programmed with a certain code in which all the parameters are defined( i.e which light is operated with which code etc.).
We use Arduino mega 2560 board which contain ATmega2560 microcontroller. Programming for this microcontroller is written generally in C++ language. This language is easy to understand as compared to other high level languages. We make a code in which we define our all parameters and make a suitable condition or a fix variable by giving that specific variable as INPUT to the board through computer runs the board to make a decision of selecting the state of light source (ON/OFF).
For this Projects we generally require the following components:
1) Arduino Mega 2560 board.
2) one 5mm Red led.
3) one 5mm Green led.
4) one 5mm Blue led.
5) Computer with Arduino IDE software. Download software Here
6) Breadboard and Jumper wires.
