Verb Switch (Week 3 – In Class)

VERB: Drop

I created a switch that lights an LED using the verb “drop”. Conductive thread connects the positive side of a coin cell battery to the anode/positive leg of an LED. The cathode/negative negative leg of the LED is connected to a sheet of copper fabric on the ground. When the coin cell battery is dropped onto the copper fabric, the circuit is completed and the LED is turned on. The battery functions as a weight to improve drop accuracy in addition to being the circuit’s power source.
