The treat dispenser is a repurposing of Patrick Jackson's Internet-enabled Candy Dispenser. The only change I did was hot gluing the auger to the servo rather than screwing them together. The idea being the hot glue functions like a sheer pin. If the auger jams the hot glue will break rather than burning out the servo.
The library has a 3-d printer which was great way to get the mounts and auger made.
The project is an easy beginner project in terms of both programming and hardware assembly. So give it a try today.
