Help with an Arduino powered TV remote? Answered

So I'm going to attempt to build a TV remote using an IR transmitter and an arduino.  I was looking up the codes for the IR codes for the TV that I have, and so far all I have found is just this website that provides a bunch of hexadecimal numbers for each function of the TV.  But I don't really know what these numbers mean.  For example, the codes would look like 0000 006D 0000 0020 0000 0046 0000 0046 0000 001E 0000 001E and have multiple rows of such numbers.  Does anybody know if these numbers are the codes to the PWM signals?  Like if the 0000 is how long the transmitter is off then if each number besides those is the time that the transmitter is on for? And therefore you get the correct pulse of the transmitter for each function? Or if this is not the case, does anybody know what these codes mean?

Loads of information about this on the arduino forums. There are libraries made for this sort of thing. Even sketches designed to used an IR reciever so your arduino can learn the codes from the original remote.

Hi! I recently did a fairly extensive project where I decoded my TV remote and retransmitted the signals. I used Github user Cyborg5's IRLib which can be found at https://github.com/cyborg5/IRLib.

If you want detailed instructions on how to use the library, check out my Instructable at https://www.instructables.com/id/Magic-Wand-TV-Remote/. Steps 2-8 go into detail on how to clone your TV remote and how to retransmit signals.
