Arduino Turn Led On&Off

A Beginners application which allows you to control one LED using a very simple electronic circuit and your Android phone.
This is the most basic project you should begin with because it's simple and easy to build.
To build this project all you need is:
- Arduino board
- 1 LED (any color you want)
- 1 Resistance (220 Ohms)
- Bluetooth module (for example HC-05)
- Android mobile.
And you are ready to build this project which will allow you to control wirelessly using Bluetooth an LED to light up by
clicking on 'ON' and to light off by clicking on 'OFF'

Important :

You must know that by clicking on 'ON' the application send '1' and '0' when clicking on 'OFF' which means that you'll have to program
your Arduino code to set the pin HIGH when receiving '1' and LOW when receiving '0'.

Or, you can simply download the code in the link bellow and upload it to your Arduino board, you'll also find an electronic
circuit that shows you how you should set your circuit.
