This was a project I completed for an introductory freshman class that focused on career exploration. In this project I decided to use a simple fun game that easily demonstrates and conveys the basic principles of electricity and how a closed loop circuit works.
This game works like the game of operation except that you have a controller (metal loop) that you have to pass through a metal wire maze. If the metal loop comes in contact with the wire maze, the circuit is completed and an LED and a buzzer goes off.
