Thanks for reply!

No programming needed since the device is based on operational amplifiers only, so basically the whole thing is made around only one integrated circuit : ka358 this chip has two internal operational amplifiers, so what I used the first one to condition the IR signal and the second one to configure a timer ,triggered by the first one. btw Do you know if I can post a video here? still in beta version so I think this is only the beginning cos we can ad more electronics or we can just use the very first stage(without timer) to keep things easy.
