I am a student. I have to do a project about infrared remote control of a wall-switch. It required to fix the frequency of the pulses generated from the IR LED and the receiver can only detect this IR single. :?
I would like to know how to do the frequency modulation of a IR LED? and how to demodulation of the receiver? As only a single switch has to be controlled, I would llike to find the simplest and cheapest circuit to do the project.
please help me.....
