today I purchased this:http://www.allelectronics.com/make-a...UZZER/-/1.html
and when I brought it home I popped in a C battery and almost immediately the buzzer went off and nearly gave me a heart attack. I quickly removed it and then tried again to find that even if I close the door the buzzer still goes off.
I then cut and soldered wires to the + contact and the wire leading into the buzzer itself into a momentary contact switch to find that nothing happens when I press it or release it.
Does anyone know how I can make this work again?
