Talk with Arduino Board using with Voice Recognition Module

 SERIAL VOICE RECOGNITION MODULE

we are learn how to talk with the Arduino Board. For this we will use the Voice Control Module. So, we can use this module to control motors, lights and robots.

Required Components :-

1. Arduino uno
2. Breadboard (or breadboard shield)
3. Voice Recognition Module (serial)
4. Microphone
5. RGB LED
6. 3x 220 Ohm resistors

Connection between Arduino* and module for recording procedure:

Module Vcc to Arduino 5V
Module GND to Arduino GND
Module RX to Arduino RX
Module TX to Arduino TX



*You must remove ATmega328p from board or program it with blink example. If you want you can also use one usb to serial board to complete this procedure.

Available commands:

Delete Group 1 - send hex AA 01
Delete Group 2 - send hex AA 02
Delete Group 3 - send hex AA 03
Delete All Groups - send hex AA 04
Record Group 1 - send hex AA 11
Record Group 2 - send hex AA 12
Record Group 3 - send hex AA 13
Import Group 1 - send hex AA 21
Import Group 2 - send hex AA 22
Import Group 3 - send hex AA 23
Query the recorded group - send hex AA 24

Circuit  Diagram :

connections are pretty easy, see the above image with the breadboard circuit schematic

switch(com)
{
case 0x11:

break;
case 0x12:
color(255, 0, 0); // turn the RGB LED red
break;
case 0x13:
color(0,255, 0); // turn the RGB LED green
break;
case 0x14:
color(0, 0, 255); // turn the RGB LED blue
break;
case 0x15:
color(0,0,0); // turn the RGB LED off
break;
}
}
}

void color (unsigned char red, unsigned char green, unsigned char blue) // the color generating function
{
analogWrite(redPin, red*102/255);
analogWrite(bluePin, blue*173/255);
analogWrite(greenPin, green*173/255);

}
