Where to find IR codes for Arduino

You might find the codes you need on the LIRC site.

FWIW I also have an LG TV and for my project used the codes found on that site. I wrote a header file with the following:

const long  PRE_DATA = 0x20df0000;    // prefix for remote command

enum COMMAND {
            up,
            down,
            left,
            right,
            ok
};

int tv_codes[] = {
                    0x02FD,       // up
                    0x827D,       // down
                    0xE01F,       // left
                    0x609F,       // right
                    0x22DD        // ok 

                    
};

Commands are sent to the TV with the function:

/*
  sendCmd
 
 Send passed commend to IR reciever.
 
 */
void sendCmd(COMMAND cmd)
{
  // combine pre data with specific code
  irsend.sendNEC(PRE_DATA | (long)(tv_codes[cmd] & 0xffff),32);

  // we must move deliberately to avoid missed clicks
  delay(300);

}

which is called, for example, like this:

sendCmd(up);

Thank you very much! That is exactly what I was looking for.
