Voice Controlled LED Using Arduino and Android Mobile

Voice Controlled LED Using Arduino and Android

In this project I will control a LED using voice command. To implement this project we need to arrange some stuff like:

1. Bluetooth Module

2. Arduino UNO

3. Android Phone

4. LED with resistor

5. And a android app namely “amr voice”

Description

Working of this project is simple. First of all we need to connect LED and Bluetooth module with Arduino.

After it upload code in Arduino.

Download AMR Voice App From Google Play Store

After successfull Connection between mobile and bluetooth module now tap at the mic symbol in app screen and

say “light on” to turned on l and “light off “ to turned off the LED

Connection are simple. Connect a LED at any pin of arduino. In my case I used 12. Connect rx and tx of bluetooth module to software serial pins tx(11) and rx(10) of Arduino respectively. And connect power supply to bluetooth module.

Coding is much simpler. Here I have used SoftwareSerial

library to enable virtual Serial port at pin 10 and 11 of arduino.

And in given picture I have compare received string with predefined string to take some needed action.
