This IR receiver based on ATtiny13 microcontroller is used to control a Media Center box via a remote. The circuit is powered by 20 pin ATX connector pin 9 “+5VSB” because it is the only pin that is powered when the computer is off, or in standby. The receiver is programmed to accept the codes from the remote by holding down the switch while pressing the remote button. The circuit can use “Girder” or “PC remote control” as controlling software on the Media Center.
