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”
Step 1: 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.
Step 2: Download AMR Voice App From Google Play Store
Now download AMR Voice App from google play store and
install it. And open it
Step 3: Connect App With Bluetooth Module
Step 4: Try It
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
Step 5: Circuit
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.
Step 6: Coding
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.
