Regarding to this IR receiver, people called this receiver as WinLIRC (Linux Infrared Remote Control for Windows). I am not the expert on this, but I have a knowledge on electronic. I follow the instruction as what the website does, it works well! Except that in term of sensitive, sometime there is a lagging (especially when watching VCD). It is not as good as how the hardware decoder does. I have simplified the circuit as above; if it’s not working please contact me.
WinLIRC allows you to transmit and receive standard infrared remote control signals. This allows it to control the pc almost any standard infrared remote control. It also allows the pc to control other equipment which uses these signals (stereo equipment).
