Fish Feeder revision

Arduino-Powered Automatic Fish Feeder (Remix)

This is a remix of the original open-source fish feeder—now refined with precise hardware upgrades and a simple manual-feed button (no screen, no on-device programming).

Core Hardware

28BYJ-48 Stepper Motor + ULN2003 Driver: Provides reliable, fine-stepped rotations for the feeding disk—no servos involved.

DS3231 Real-Time Clock: Ensures accurate, hands-off scheduling through power cycles.

3D-Printed Bearing Assembly: PETG-printed low-friction bearing guarantees wobble-free rotation.

Integrated Stand: Elevates the feeder above the tank rim with anti-slip feet and hidden cable channels.

Manual Feed Button: A single tactile button lets you dispense an extra portion on demand.

Key Features

Code-Defined Schedule: Feeding times and portion sizes are set directly in the Arduino sketch—no menu navigation needed.

Portion Calibration: Adjust step counts in firmware to deliver the perfect amount of flakes or pellets.

Instant Override: Pres
