What would you like to do?
Arduino Sketch recording raw IR signal and sending it through an infrared LED again every 2 seconds
#include <IRremote.h>
int RECV_PIN = 11;
IRrecv irrecv(RECV_PIN);
IRsend irsend;
boolean recording = true;
decode_results results;
void setup()
irrecv.enableIRIn(); // Start the receiver
void loop() {
if (recording) {
if (irrecv.decode(&results)) {
Serial.println("IR code recorded!");
//irrecv.resume(); // Receive the next value
Serial.print("Recorded ");
Serial.println(" intervals.");
recording = false;
} else {
// replay mode
Serial.println("Sending recorded IR signal!");
irsend.sendRaw((unsigned int*) results.rawbuf, results.rawlen, 38);

thank you for sharing this Arduino code on Github. I was trying to switch on my TV with Arduino. The code you posted is able to get the code and try to re-send, but the TV doesn't switch on. The IR LED light every 2 seconds. What do you think is the problem ? Should I insert any resistor from the PIN 3 to the IR LED ? I hope to hear you back.

I want to know too. that doesnt work for me. capture but doesnt send any data

It's receiving but not sending - (I use a couple of transistors, because I have a lot of IR LED's in my project)

For those who are able to receive and not send, though this might be obvious, check if you have an IR transmitter sensor module/support. If it's only an IR receiver sensor module you have, sending the IR codes back on a certain pin, after receiving will be just of no use! I am saying this from my earlier experience when I started playing with them! :) Cheers.

hello everyone, iam doing a project i.e using ir remote codes to control the consumer products using arduino, ir receiver and ir led. i controlled the NEC protocol products but i didn't control the SAMSUNG protocol devices .i want control the LLOYD AC .it has SAMSUNG protocol .can you please help me.
thank you.
