Build voice controlled applications using Arduino and implement it to control the home apliences and other systems. Here i made this simple voice controlled LED'S using Arduino pro mini and HS-05 bluetooth module.The hardest part in voice control system is converting speech to text or string. But it becomes simple. Google Voice recogonisation is there to convert to speech to text.

Step 1: VIDEO
Step 2: COMPONENTS
Get this components from local electronics shop.
Arduino pro mini x 1
HC-05 Bluetooth module x 1
Android Mobile x 1
Breadboard x 1
LED x 2
100 ohm resistors x 2
Step 3: CIRCUIT
connect the components as per the circuit diagram. And upload the sketch to Arduino pro mini. Important thing is disconnect the HC-05 module and then upload or otherwise it shows error message.
Step 4: PROGRAMMING
Download program here
To change voice command remove the text inside the astrix(*) and place the command which you need.
Step 5: HOW IT WORKS
First download the android app from play store and upload the sketch to Arduino pro mini and pair your Bluetooth module with your phone.
speech is recogonised by the android app and it converts recived voice to text then it sends text as string to HC-05 BLUETOOTH Module. then the recived text is identified by Arduino. then the digital output signal is produced to control the LED's.
