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();
}
}
