Deadline Neko – A Cat’s Paw Interrupting Document Writing

For the theme “Unnecessary Inventions,” we crafted a whimsical device with a cat’s paw that keeps pressing the delete key whenever a user sets their mug on its accompanying coaster.

A user put a cup of water on the coaster, actuating the cat's paw to press the delete key. The device was built with a photoresistor, a servo motor, and Arduino.
