YouTuber “Mom Will Be Proud” and his family have a cat. And like all pets, their feline friend requires fresh food every morning. But rather than disrupt your sleep or daily routine, why not build an automated feeder using some spare parts? This is exactly what the Maker did using an Arduino, a servo, a simple button, a power supply, and two cans–one for housing the electronics, the other for the food.
Mom Will Be Proud cut little openings into each container, and connected them to a servo that rotates one on top of the other without ever getting stuck. A broken IKEA timer and a piece of plastic are used for the button, which when pressed, turn the cans until its holes match up and the food is dispensed into a bowl.
