Simple Home Automation Using Bluetooth, Android and Arduino

Take control of your home in your smart-phone with the simplest ever home automation device.

The Code:-


String voice;
#define relay1 2    //Connect relay1 to pin 2
#define relay2 3    //Connect relay2 to pin 3
#define relay3 7   //Connect relay1 to pin 2
#define relay4 8    //Connect relay2 to pin 3
void setup()
{
  Serial.begin(9600);            //Set rate for communicating with phone
  pinMode(relay1, OUTPUT);       //Set relay1 as an output
  pinMode(relay2, OUTPUT);
  pinMode(relay3, OUTPUT);      //Set relay2 as an output
  pinMode(relay4, OUTPUT);
  digitalWrite(relay1, LOW);     //Switch relay1 off
  digitalWrite(relay2, LOW);     //Swtich relay2 off
  digitalWrite(relay3, LOW);     //Switch relay1 off
  digitalWrite(relay4, LOW);     //Swtich relay2 off
}
void loop()
{
  while(Serial.available())    //Check if there are available bytes to read
  {
    delay(10);                 //Delay to make it stable
    char c = Serial.read();    //Conduct a serial read
    if (c == '#'){
      break;                   //Stop the loop once # is detected after a word
    }
    voice += c;                //Means voice = voice + c
  }
    if (voice.length() >0)
    {
      Serial.println(voice);
      if(voice == "*switch on"){
        switchon();
      }               
      else if(voice == "*switch off"){
        switchoff();
      }             
      else if(voice == "*bulb1 on"){   
        digitalWrite(relay1, LOW);
      }
      else if(voice == "*bulb1 off"){
        digitalWrite(relay1, HIGH);
      }
       else if(voice == "*bulb2 on"){   
        digitalWrite(relay2, LOW);
      }
      else if(voice == "*bulb2 off"){
        digitalWrite(relay2, HIGH);
      }
       else if(voice == "*fan1 on"){   
        digitalWrite(relay3, LOW);
      }
      else if(voice == "*fan1 off"){
        digitalWrite(relay3, HIGH);
      }
      else if(voice == "*fan2 on"){
        digitalWrite(relay4, LOW);
      }
      else if(voice == "*fan2 off"){
        digitalWrite(relay4, HIGH);
      }
      voice="";
    }
}
void switchon()               //Function for turning on relays
{
  digitalWrite(relay1, LOW);
  digitalWrite(relay2, LOW);
  digitalWrite(relay3, LOW);
  digitalWrite(relay4, LOW);
}
void switchoff()              //Function for turning on relays
{
  digitalWrite(relay1, HIGH);
  digitalWrite(relay2, HIGH);
  digitalWrite(relay3, HIGH);
  digitalWrite(relay4, HIGH);
}

    One another Q is
    define relay1 2 //Connect relay1 to pin 2
    #define relay2 3 //Connect relay2 to pin 3
    #define relay3 7 //Connect relay1 to pin 2

    In 3rd row,
    Why "relay3 7"?
    Its "relay3 4"
    Is it correct or not please explain.

    In 3 row comment,
    Why "relay3 7" connect relay1 to pin 2
    Its "relay3 7" connect relay3 to pin 7
    Is it correct or not please explain

    Thank you.

    bro the code ran successfully and i connected the BT in the ApK file you have attached. the problem am facing is, that on clicking the button "ALL ON ,ALL OFF ,etc" or on any other button my relays are not getting off
    please guide me.. am python programmer myself and i checked your code but there is no line of code related to HC-05 module. please guide me how can i overcome the issue i've told you.

    An impressive share, I just now given this onto a colleague who had previously been doing little analysis about this. Anf the husband the fact is bought me breakfast simply because I stumbled upon it for him.. smile. So permit me to reword that: Thnx for your treat! But yeah Thnkx for spending some time to debate this, I find myself strongly over it and enjoy reading more about this topic. If possible, as you become expertise, might you mind updating your site with more details? It truly is highly of great help for me. Huge thumb up because of this text! buy wallpaper
