Hello,
I am trying to make a decoder for IR remote control.
I have found many sites on the internet with a loto of information.

From where do I can start?

Years ago I wrote a simple program that reads from a IR photo diode to a PC parport pin,
or any other thing you have, to record the IR commands from my cable modem.

 scroll down to 'finding out your codes'.

it saves those as files, one for each commad (you type the code on a remote and record it).
The top of that site shows you how make a module to then transmit those codes, but that requires a micro.
If your PC is fast enoiugh it can do that too.

Hacking cars .. well you know...
I had a similar system for listening and recording RF codes and then re-transmitting those,
with tx and rx modules I bought,  basically a replay attack.
