# Meaw Pet Feeder: Firmware

## Introduction

This project implements the firmware for an ESP32-based pet feeding device, where the user can schedule the times at which food portions need to be served. 


The device works together with a Mobile App, through which it can also be controlled. 


**Make sure to also visit the App respository:** [Meaw-PetFeeder-App](https://github.com/MatheusCavini/Meaw-PetFeeder-App)

The project was created as part of the discipline "Embedded Systems" (PMR3402) for my Mechatronics Engineering course at Escola Politécnica da Universidade de São Paulo (USP).

## Features

• Connect to mobile app using a device ID code; 


• Program up to 30 daytimes at which food is to be served; 


• Erase existing times; 


• Serve food at anytime by selecting "serve now";


• Get an alert when the food level in the reservoir is low.

## Technical Aspects

- The firmware of the device runs a state machine, processing external (user inputs, app connection) and internal (reaching a saved time, low level) events to switch between different states.


- FreeRTOS is used to run simultaneous tasks such as the state machine, checking food level and checking current time.


- Current time is obtained via internet. Further improvements may include a physical Real Time Clock module. 


- The physical device serves an API, to which the app connects and makes requests.
