How to send the detected button code using the https://github.com/z3t0/Arduino-IRremote library.

}

void loop() {

        Serial.println(infraRedReceiverResults.bits);
    }
    
    infraRedReceiver.resume();
  }
}

void printDemo(const char *functionName){
  Serial.print(functionName);
  Serial.print(functionName);
  Serial.print("(0x");
  Serial.print(infraRedReceiverResults.value, HEX);
  Serial.print(", ");

}

emitter.c

#include <IRremote.h>

IRsend irsend;

void setup()
{
}

void loop() {
  // Send the code:
  irsend.sendSAMSUNG(0xB24D7B84, 32);
    
  // Wait 10 seconds to send it again:
  delay(10000);
}

expectedOutput.c

irsend.sendNEC(0x20DF22DD, 32);
irsend.sendNEC(0x20DFE01F, 32);
irsend.sendSAMSUNG(0xB24D7B84, 32);
irsend.sendNEC(0x20DFC23D, 32);
