Wireless Pet Treat Dispenser using Arduino Nano RP2040

One of our friends recently adopted a senior dog called Jelly who suffers from separation anxiety. To help with training him when he needs to be left on his own, they asked us to make a wireless treat dispenser to go with the pet camera they already own. In the video, we demonstrate the principle with the help of Timothy, our rabbit.

Overall design

This treat dispenser is designed to hang from a wall hook and is controlled wirelessly over WiFi, via an app on the user’s phone. There are 8 slots for treats, dispensed using a servo. These compartments might be large enough to hold food for a couple of days for smaller pets, such as hamsters or fish, especially with modifications. However, for our purpose, we only wanted to hold a few small dog treats.
