Please help me with my school project!! I'm in AP Physics in High School right now, and the teacher just assigned our class to design a locker alarm. It must turn on when the locker is opened and turn off when the locker is closed. However, there's a restriction: the alarm must turn on when 2 wires separate, not when they come together. I'm pretty stuck with this project because of the restriction...anyone has any idea on how to build the alarm in a way that would satisfy the restriction?? Thank you very much!!
