Is it possible to make a PIR sensor turn a small electric motor?
I need to have a PIR sensor turn a modded servo, but i can't get it to work. The servos electronics have been taken out, so its just a gearbox, and works like a normal motor. I have tried using a transistor as a switch for the servo, it works for an led, but when the motor is put in the leds place it just spins non stop. I have no clue what else to try, or why its acting to erratic. I have also tried just going straight from the PIR sensors output, but no luck there either. Does anybody know how to do this without a micro controller? and could you provide a schematic. Thanks.
