Food Switch

I set out to create a circuit that would react differently to different kinds of food. I chose a representative of the vegetable food group (broccoli / potato) and a representative of the animal food group (McDonald’s bacon cheeseburger) to be the ‘switch’. When the switch is ‘closed’, the circuit decides how to power the LEDs and sound the piezzo buzzer.
