“Switch without the use of hands” was what we were asked to create for our first assignment. In the process of making the circuit, the assignment reminded me of the time when I was in the military where people would frequently cheat the number of pushups they do. Since the pushups were counted by human eyes, it was hard for people to know whether a pushup was done correctly. With this switch, we will know whether the person is doing the push up right.
For this switch, there is a wooden base with disconnected foils on the surface. The cloth on top has a foil placed beneath, and when the cloth touches the surface of the base, the circuit becomes complete.
