Receiving IR code and transmitting signal with KY-005 to product.

Projects Programming

I have LG remotecontroller and with KY0022
whenever I pressed power button on Remotecontroller and get code like below

81E2817E
FFFFFFFF
FFFFFFFF
FFFFFFFF

but How can I send above signal to turn on/off product?

My code to receive and send signal is as below.

#include <IRremote.h>

int RECV_PIN = 13;
int sw1 = 10;
IRrecv irrecv(RECV_PIN);

decode_results results;
 IRsend irsend;
void setup()
{
  Serial.begin(9600);
  // In case the interrupt driver crashes on setup, give a clue
  // to the user what's going on.
  Serial.println("Enabling IRin");
  irrecv.enableIRIn(); // Start the receiver
  Serial.println("Enabled IRin");
}

void loop() {
  delay(2000);
    for (int i = 0; i < 3; i++) {
      Serial.println("sending");
  irsend.sendLG(81E2817E, 28);   //SAMSUNG TV LED on/off   (capturado con IRrecvDumpV2.ino)
  delay(40);
 }
  
   
  if (irrecv.decode(&results)) {
    Serial.println(results.value, HEX);
    irrecv.resume(); // Receive the next value
  }
  delay(100);
}

void loop() {
  delay(2000);

Of what possible benefit is it to stick your head in the sand for two seconds EVERY time loop() iterates?

  irsend.sendLG(81E2817E, 28);

Did you bother to read the documentation for this function? I don't think you did. Otherwise, your code wouldn't look anything like that.

Why do you (try to) send that on every pass through loop()?

The real question is why don't you just aim the remote at the TV, instead of the Arduino.

Try the example IRRemote->IRRecvDumpV2. It will generate the Arduino code for you.
