i want to buid and ir transmiter and receiver. Because of size and cost of building 100's I dont know if i want to use an encoder/decoder chip.
Can a circuit for RECIEIVER be built that would discriminate frequency? in other words if its say 38kHz receiver says ok I Like you. if its Higher, say 39kHz receiver ignores signal. I found a receiver circuit that displays frequency on a meter in amps. any ideas if its possible? I want to make about 8 dif. transmiters (1 freq each)
Thanks,
Scott
