So I have this circuit built (shown in the attachments) what it does is that you plug the battery in, turn the switch on, put it in a dark room, and once light hits the photo cell the buzzer starts going off. However, I want to modify the circuit so that I can put a weight sensor on it so that it will go off when someone steps on the two aluminum rectangles. I haven't finished making the weight thing yet but I was putting it off because I didn't even know if it was possible to put a weight sensor switch on this circuit, and if so, can someone explain to me how it is possible, thank you!
