Coin Unconventional Switch - Team 12

Soria Elhassan & Kylie Welch


Unconventional Switch: Coin


We created our unconventional switch using an LED, alligator clips, a 1000 ohm resistor, dimmer, circuit playground, and a coin. Starting with the circuit playground’s 3.3V produced for usage, it then goes through our 1000 ohm resistor. The coin then conducts the electricity to go through the dimmer, which allows us to reduce and gain lighting in the LED. Which then connects to the ground in the circuit playground to complete a full circuit. It’s unconventional due to the use of the coin because when the war hits and all you have is a quarter to your name, you too can make sure you have enough light to see the plans of the rebels in the darkest nights.
