driving relay with pir
My 9 year old son is very interested in science and is working on a project that involves hooking up a motion sensor (PIR) to a clock alarm. The challenge is to get the PIR to de-activate a sounding alarm. We thought if we could create a circuit that closed when the PIR was activated, it just might do the trick. We have the PIR and the clock as a start - All thoughts are greatly appreciated!
