Lab: Closing a Circuit


For the third week’s assignment, we had to design a switch or pushbutton in order to close an electrical circuit.

A switch is a mechanism to bring two separate pieces of conductive material, allowing the flow of electrical current.

Since you can make a switch from any conductive material, I decided do make a switch out of water and gravity.

Water helps connecting the two metallic wires at the sides of the cup, closing the electrical circuit and lighting the LED in the breadboard.
