hi im looking for a proximity sensor cicuit ive looked around and i couldnt find one i want it to activate some kind of buzzer i dont really want anything complex just a real simple proximity sensor anyone has one?
hi harm, take a look at this page. Build the last circuit. It worked for me. It won't latch though, it will only stay on if a hand is close to it (only a couple inches). It could be amplified though so it would be a couple feet.
