Arduino Voice Controller 2.0 APK

hardware : arduino uno ,5 channel relay module,HC-06 or hc-05

connection: vcc of hc to 5 volt of arduino
grd of hc to grd of arduino
tx of hc to rx of arduino
rx of hc to tx of arduino

arduino uno pins:2,3,4,5,6

voice command: on (turn all the channel on)
off(turn all the channel off)


arduino code:
char data = 0; //Variable for storing received data
void setup()
{
Serial.begin(9600); //Sets the data rate in bits per second (baud) for serial data transmission
pinMode(2, OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);

}
void loop()
{
if(Serial.available() > 0) // Send data only when you receive data:
{
data = Serial.read(); //Read the incoming data and store it into variable data
Serial.print(data); //Print Value inside data in Serial monitor
Serial.print("\n"); //New line
if(data == '1')
