Remote Controlled House

          This project is to control the home appliances using normal TV remote. It used an arduino board, relay and a TSOP to receive signal from the remote and the control the home appliances. Connect the TSOP with arduino. Connect the 5V and Gnd of TSOP to 5V and Gnd of the arduino and connect the data pin of the TSOP to arduino digital pin 2. Connect the digital pin 10 of the arduino to the relay

Components needed

• Arduino UNO or atmega8 Microcontroller ( Rs.1300 for Arduino or Rs.80 for atmega8 microcontroller )
• TSOP ( Rs. 10 )
• 5V Relays ( Rs. 30 )

Program

#include <IRremote.h>

int TSOP_PIN = 2;  // Arduino pin where the TSOP is connected

IRrecv irrecv(TSOP_PIN);

decode_results results;

int i = 0;

void setup()

{  

pinMode(10,OUTPUT); // Connect relay to pin 10 of the Arduino

pinMode(2,INPUT);  

digitalWrite(2,HIGH);  

irrecv.enableIRIn();

Serial.begin(9600);

}

void loop()

{  

if (irrecv.decode(&results)) 

{    

Serial.println(results.value); // Prints the value from remote in Serial monitor    

if(results.value==33) // Change the value according to your remote  

{

digitalWrite(10,HIGH); // Switches on the relay

}

else

{

digitalWrite(10,LOW); // Switches off the relay

}

delay(300);// delay to avoid repeated value

irrecv.resume(); // To receive the next value from IR remote

    

}

}

Troubleshooting

The program won't compile until you copy and paste the libraries in the My documents folder.

The libraries are available at

https://github.com/shirriff/Arduino-IRremote

TSOP

Connect the Gnd to arduino Gnd

Connect the Vs to arduino 5V

Connect the OUT to arduino pin 2

Relay Circuit

Connect the digital pin 2 of the arduino to the base of the transistor.

Connect the Gnd of the arduino to the relay circuit Gnd.
