Tau reikia pries procesoriu demoduliatoriaus, jeigu neklystu.

There are plenty of Detectors for receiving the bitstream of an IR
remote control but the best
I ever used is the TSOP1836 of VISHAY.
The TSOP1836 is a 3 pin device that receives the infrared bursts and
gives out the demodulated bitstream at the output. The RC5 code is an easy
protocol to decode with a pic mircrocontroller . I will show an example to
control your PC when it's finished
