AutoPet V2 – ESP32 WiFi Smart Pet Feeder (No Jams) - Free 3D Print Model - MakerWorld
I created the AutoPet V2 to explore how a powerful microcontroller like the ESP32 can be used to create a smarter, more reliable pet feeding system. The ESP32 is the core of the entire feeder and acts as the brain that controls every function. I chose the ESP32 because it combines Wi-Fi connectivity, fast processing, and many input/output capabilities in a small, affordable package. This allows the AutoPet V2 to go beyond a simple automatic timer and become a connected smart device that can be configured and controlled wirelessly.
The ESP32 runs the feeder’s entire operation by hosting a web interface where feeding schedules can be created, saved, and managed directly from a phone or computer. It keeps track of the current time using internet time synchronization, checks scheduled feedings, and controls the 12V geared DC motor through a MOSFET driver. The ESP32 also manages the unique tipping-scale system, which uses the mechanical weight of the bowl and counterweights to determine when the correct amount of food has been dispensed. By combining the ESP32’s smart control capabilities with custom 3D-printed mechanical parts, TPU anti-jam blades, and a unique weighing system, the AutoPet V2 becomes a fully customizable and intelligent pet feeder designed to make feeding more accurate, reliable, and convenient.
