Arduino MEGA with HC06

Introduction

Basically in home automation system we have a wireless switch to control different devices. But in this project we can control devices over our voice. Mega have 54 digital pins so we can connect vast number of devices using this board.

This project will be helpful for physically challenged people who can use their voice to control anything.

Code

Voice controlled

String readString;
void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(13, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
while(Serial.available()){
  delay(3);
  char c = Serial.read();
  readString+=c;
}

if(readString.length() >0)
{
  Serial.println(readString);
  if(readString == "11")
  {
  digitalWrite(13, HIGH);
  }
 else if(readString == "12")
  {
  digitalWrite(13, LOW);
  }
   else if(readString == "21")
  {
  digitalWrite(12, HIGH);
  }
   else if(readString == "22")
  {
  digitalWrite(12, LOW);
  }
  readString = "";
}
}
