Hi, I want to make an RC car (don't we all ) and I have figured out that I need an astable with an output of IR LED. The question is, how do I set up an IR receiver? I have heard about and seen components which are IR receivers, but they only respond to 38kHz or so. I want a receiver circuit, just to switch a motor on/off and it can be modified to "accept" certain frequencies, but not interference from other transmitters, so that the frequencies can be differentiated. I.e. a transmitter of 5kHz and matching receiver, and another 30kHz transmitter with matching receiver, without interference from one another. Much appreciated.
BTW, I am a complete newbie, so the simpler the better. Thanks for your time.
