Unconventional switch - Squeezing out the light
Description
For this project, I created an unconventional switch that lights up an LED by squeezing a lemon. I used components from my most complete starter kit, including a breadboard, jumper cables, an alligator clamp, a power source adapter set to the 5V configuration, and a multimeter to check everything was working properly.
What did I use for this? A metal lemon squeezer and an actual lemon. The objective was to demonstrate how electricity can flow through everyday items, even edible ones like fruit, and how a simple action we normally use to make lemonade or juice can be transformed into something completely different, like turning on a light.
It's a fun way to show that conductive materials are everywhere, and sometimes the most interesting circuits come from thinking outside the box.
