Usage
- You need a IR receiving breakout to detect the IR signal and decodes it as HEX code, then dispaly it on the serial monitor.
S -> D11 VCC -> 5V GND -> GND
- When you press any button on the remote control, serial monitor shows the hexadecimal code of that button.Every button on the remote control has a corresponding hexadecimal code. When you keep on any pressing the button, it shows FFFFFFFF on the serial monitor. As well as the IR transmitter and receiver module, keep the IR LED on the remote control opposite the IR detector for better signal reception.
Example code
#include <IRremote.h> int RECV_PIN = 11; //define input pin on Arduino IRrecv irrecv(RECV_PIN); decode_results results; void setup() { Serial.begin(9600); irrecv.enableIRIn(); // Start the receiver } void loop() { if (irrecv.decode(&results)) { Serial.println(results.value, HEX); irrecv.resume(); // Receive the next value } }
