As part of our first homework assignment (digital input and output) we were asked to reinterpret what an electrical switch can be. I wanted to do something with a smile, so this lead to a mustache-like apparatus as the electrical switch. Smiling transforms this aluminum switch from a “closed” Burt Reynolds mustache into an “opened” fu manchu mustache. White wires on both aluminum ends lead back to the Arduino board controlling no-smile to the red LED and smile to the green LED.
Green light = Smile!!!
