Serial port Infrared Receiver

Posted on Mar 18, 2013

This is a general purpose serial port infrared receiver. With the help of appropriate software (see below) you can control different functions of your pc from a distance. For example you can control your home cinema settings (volume, play, pause, stop etc), your winamp etc. It uses for receiver TSOP 1738 (38 KHz) but it worked well with TSOP 1736 (36 KHz) and a remote Sony which works at 40Mhz. The two transistors light up the led when a signal is received. Any kind of led will fit.
