Introduction

Once the Bluetooth connection has been established, all you need to do is click on the eight ON/OFF buttons below, giving you the ability to control the load appliances in accordance with your specific requirements.

Code

char data = 0;

void setup()

{

Serial.begin(9600);        

pinMode(3, OUTPUT);   // Define output pin no 3

pinMode(4, OUTPUT);   // Define output pin no 4

pinMode(5, OUTPUT);   // Define output pin no 5

pinMode(6, OUTPUT);   // Define output pin no 6

pinMode(7, OUTPUT);   // Define output pin no 7

pinMode(8, OUTPUT);   // Define output pin no 8

pinMode(9, OUTPUT);   // Define output pin no 9

pinMode(10, OUTPUT);   // Define output pin no 10

}

void loop()

{

if(Serial.available() > 0)  

{

data = Serial.read();      

Serial.print(data);        

Serial.print("\n");        

if(data == 'A')            

digitalWrite(3, LOW);   // Turn relay 1 ON

else if(data == 'a')    

digitalWrite(3, HIGH);    // Turn relay 1 OFF

  if(data == 'B')            

digitalWrite(4, LOW);   // Turn relay 2 ON

else if(data == 'b')    

digitalWrite(4, HIGH);    // Turn relay 2 OFF

if(data == 'C')            

digitalWrite(5, LOW);   // Turn relay 3 ON

else if(data == 'c')    

digitalWrite(5, HIGH);    // Turn relay 3 OFF

if(data == 'D')            

digitalWrite(6, LOW);   // Turn relay 4 ON

else if(data == 'd')    

digitalWrite(6, HIGH);    // Turn relay 4 OFF

if(data == 'E')            

digitalWrite(7, LOW);   // Turn relay 5 ON

else if(data == 'e')    

digitalWrite(7, HIGH);    // Turn relay 5 OFF

if(data == 'F')            

digitalWrite(8, LOW);   // Turn relay 6 ON

else if(data == 'f')    

digitalWrite(8, HIGH);    // Turn relay 6 OFF

if(data == 'G')            

digitalWrite(9, LOW);   // Turn relay 7 ON

else if(data == 'g')    

digitalWrite(9, HIGH);    // Turn relay 7 OFF

if(data == 'H')            

digitalWrite(10, LOW);   // Turn relay 8 ON

else if(data == 'h')    

digitalWrite(10, HIGH);    // Turn relay 8 OFF

}  

}

Conclusion

Home automation is becoming more popular nowadays because it release us from the tension of manually operating devices and it will become the future of Electronics

Future Work

· Voice Control to control devices

· Using Wi-Fi to Control Devices and Operate them remotely
