Using this voice activation module is really easy once you know how to program the module with your voice commands.
I can say that it was a major headache (for me anyway) to get this thing programmed with my voice commands, mainly because there is practically no info on how to use the module.

Firstly to program the voice module you need a USB-TTL Converter you can grab one off ebay for a few bucks a good seller gadgetinfinitewhich i have bought many things from.
Once you have your USB-TTL and your Voice Recognition Module then you are ready to program it with you commands. You need to download AccessPort Serial commander. Setup your settings same as below except the com port number you are connected to.
Now to start to program your commands.
In the terminal you will see this
START �say command now
Again �repeat command now
START �repeat command now
Finish one �omg one command is set
Again �repeat command now
START �repeat command now
Finish one �omg one command is set
Remeber it goes straight into the next command no breaks. Continue until you see
Group1 finished !
Hooking up to Arduino is easy. Ground, VCC, RX to TX, TX to RX. Now we just need some Arduino code to test the module.
int ledPin = 13;
byte com = 0; //reply from voice recognition
void setup()
{
Serial.begin(9600);
pinMode(ledPin, OUTPUT); // sets the ledPin to be an output
delay(2000);
Serial.write(0xAA);
Serial.write(0x37);
delay(1000);
Serial.write(0xAA);
Serial.write(0x21);
}
void loop() // run over and over again
{
while(Serial.available())
{
com = Serial.read();
switch(com)
{
case 0x11:
digitalWrite(ledPin, HIGH);
break;
case 0x12:
digitalWrite(ledPin, LOW);
break;
case 0x13:
break;
case 0x14:
break;
case 0x15:
break;
}
}
}
