The pet feeder is an open source project made for all kinds of dogs, being large or small breed, supporting different sizes of food. The first physical version can be found here.

The application was developed in Android Studio using Java, before the development phase, a Figma prototype was created and tested with users. 

The application allows the user to control the feeder and have a personal tracker of the profile of the pet, allowing users to save information about their pet such as: Name, microchip number, age, weight, gender, as well as vaccine dates and history of meals. 

It's possible to have many feeders, for the case when the person have more than one pet.

The source code for the project can be found here.

On the previus project we used an Arduino for the circuit, but for the application to work we opted to use an ESP 32. The screen is not part of this project, but it can be found on the previous version.

We created a smaller version of the feeder, that used the same screw to support many sizes of food, but have a smaller storage, since the goal was to create the application for the pet feeder.
