CMOS IR Transmitter
CMOS IR Transmitter
Just about every control process can be handled elegantly with a microcontroller — even generating infrared signals. Sometimes there’s an even easier method, using the time-honored CMOS logic. A case in point is the circuit offered here for an IR jamming transmitter, which can knock out (paralyze) popular remote controls using (not only) the widely used RC5 code protocol.
