Food Consumption Track & Automatic Refill w/ ESP32 + MQTT (Prototype)

Project for an animal shelter, monitoring food consumption and refilling the bowl when the food is finished. The computation is handled by the ESP32, the code it's modular (if the food storage system is not present), and can handle physical errors. The messages are sent via MQTT to AWS, where we keep track of the consumption.
Requires an ESP32, scale, light sensor and laser, motor for dropping food, motor for sliding door, and two buttons for detecting when it's closed or open.
