Objective:

         To display the values corresponds to each key of a Remote Controller unit

Components Required

• Arduino Uno
• IR Receiver Module

Connection Diagram

Program

#include<IRremote.h>

int RecvPin = 10;

IRrecv irrecv(RecvPin);

decode_results results;

void setup()

{

Serial.begin(9600);

irrecv.enableIRIn();

}

void loop()

{

if (irrecv.decode(&results))

{

Serial.println(results.value, HEX);

irrecv.resume();

delay(1000);

}

}

Working

         Whenever we press any button in the Remote Controller it emits a Hexa Decimal Value corresponds to it. This value is captured by using the IR receiver module and can be used to identify the key pressed at the Remote Controller in wireless medium.

Output

Key Value : 272

Note : Before executing the program install the Library “IRremote.h”
