Automatic Fish Feeder
Embedded MicroPython system that automatically feeds fish at scheduled times.
About the project
The automatic fish feeder is a compact embedded system that uses an ESP32 with MicroPython to feed fish at fixed
times.
The DS1307 RTC stores all feeding times persistently and a continuous-rotation servo dispenses food precisely.
This project demonstrates experience with embedded software, hardware control, threading, and lightweight network communication.
Key components
Time-controlled feeding
- 18 configurable time slots
- Persistently stored in RTC-NVRAM
- Works without Wi-Fi dependency
Servo control
- PWM-controlled continuous-rotation servo
- Separate thread for timing
- Reliable behavior during network activity
Manual operation
- Physical button (with debouncing)
- Immediate feeding, even without network
Network features
- Small TCP protocol for remote configuration
- Reading and setting via a client
- Automatic NTP sync (with failsafe logic)
Result
An autonomous, reliable and easily configurable system that precisely executes feeding times - ideal as a demonstration of firmware development, low-level hardware, and embedded architecture.
