For our first assignment, we were asked to design a switch that turned on an LED without using hands. For my project, I wanted to incorporate a book and a book mark that would align to light up the LED.
To do so, I created a bookmark out of foil and copper tape and added a foil lining to a page in a book (ideally, this would exist on every page). Both the page and the bookmark were connected by wires to the breadboard to complete the circuit where an LED would light up once they were in place.
I also, just for fun, decided to attach wires to magnetic salt and pepper shakers to complete the circuit.
