Arduino Control Two Leds by Bluetooth

Kết hợp điện thoại Android của bạn với Arduino để điều khiển hai đèn LED sử dụng Bluetooth.

A Beginners application which allows you to control two LEDs using a very simple electronic circuit and your Android phone.

This is one of the basic projects you should begin with because it's simple and easy to build.

To build this project all you need is:

- Arduino board

- 2 LED (any color you want for example Green and Red)

- 2 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 Two LEDs to light up by

clicking on 'ON' and to light off by clicking on 'OFF'

Important :

You must know that by clicking on 'RED_ON' the application send '1' and '0' when clicking on 'RED_OFF' and by clicking on 'GREEN_ON' the application send '3' and '2' when clicking on 'RED_OFF' which means that you'll have to program

your Arduino code to set the first pin HIGH when receiving '1' and LOW when receiving '0' and set the second pin HIGH when receiving '3' and LOW when receiving '2'

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.
