Example Code

Checking Infrared Reception Values per Button Press

Displays the value corresponding to the pressed button on the remote control to the serial monitor.

#include <IRremote.h>

#define irOut A0

IRrecv irrecv(irOut);

void setup() {
  Serial.begin(9600);
  Serial.println("Serial start");
  irrecv.enableIRIn();
}

void loop() {
  if (irrecv.decode()) {
    Serial.println(irrecv.decodedIRData.decodedRawData);
    irrecv.resume();
  }
}

Main Code

Turns on the LED when a button on the remote control is pressed.

#include <IRremote.h>

#define irOut A0

IRrecv irrecv(irOut);

void setup() {
  Serial.begin(9600);
  Serial.println("Serial start");
  irrecv.enableIRIn();
}

void loop() {
  if (irrecv.decode()) {
    Serial.println(irrecv.decodedIRData.decodedRawData);
    irrecv.resume();
  }
}
