Single Button IR Remote

It's all posted above my friend, but I will link the code below if that will help. Sorry for any confusion :slight_smile:

// sensible name for when the button is pressed
// use when using a pullup resistor; change LOW to HIGH when using a pulldown resistor
#define ISPRESSED LOW
// number of preser channels
#define NUMPRESETS 6
// maximum number of 'digits' in preset
#define MAXDIGITS 3

#include <IRremote.h>
#include <IRremoteInt.h>

// switch pin
const int switchPin = 2;

// Create IR Send Object
IRsend irsend;

// selected preset
uint16_t selectedPreset;
// array with IR codes to be sent
// below contains 2 entries for presets; others default to all zeroes
// if a single digit (e.g. 1 instead of 001) is needed, populate the last one of the 3 and set the others t 0x0000
// this assumes that there is no code that uses 0x0000; you can change it to any unused code
uint16_t presets[NUMPRESETS][MAXDIGITS] =
{
  {0x0C06, 0x0C00, 0x0C01}, // preset 1; 601
  {0x0C06, 0x0C01, 0x0C04}, // preset 2; 614
  {0x0C06, 0x0C01, 0x0C05}, // preset 2; 615
  {0x0C06, 0x0C01, 0x0C07}, // preset 2; 617
  {0x0C06, 0x0C02, 0x0C00}, // preset 2; 620
  {0x0C06, 0x0C02, 0x0C03}, // preset 2; 623
};

void setup()
{
  // serial for debugging purposes
  Serial.begin(57600);
  // Set Switch pin as Input
  pinMode(switchPin, INPUT_PULLUP);
}

void loop()
{
  // variable to remember the last button state; initialised to NOT ISPRESSED
  static int lastButtonState = !ISPRESSED;
  // read the pin
  int buttonState = digitalRead(switchPin);

  // if the button changed from RELEASED to PRESSED or the other way around
  if (buttonState != lastButtonState)
  {
    // remember the change
    lastButtonState = buttonState;

    if (buttonState == ISPRESSED)
    {
      
        // increment the preset
        selectedPreset++;
        // if we've reached the end of the presets, reset counter
        if (selectedPreset == NUMPRESETS)
        {
          selectedPreset = 0;
        }
        // send the IR code(s)
        sendIRCommand();
      }
    }
  }
  // simple debounce delay
  delay(50);
}
/*
  send IR code to receiver
*/
void sendIRCommand()
{
  Serial.print("Sending preset ");
  Serial.println(selectedPreset + 1);
  for (int cnt = 0; cnt < MAXDIGITS; cnt++)
  {
    if (presets[selectedPreset][cnt] != 0x0000)
    {
      // display the information
      Serial.print(presets[selectedPreset][cnt], HEX);
      Serial.print(" ");

      // send the ir code to the TV (based on the code from your opening post)
      irsend.send***(presets[selectedPreset][cnt], 10); // TV code

      delay(500);
    }
  }
  Serial.println();
}

The error I am now getting is "'sendIRCommand' was not declared in this scope" honestly I am a bit clueless at this stuff and you guys have been very helpful.
