This project provides an automated voice-activated pet
feeder system using an ESP32 microcontroller, an HC-05 Bluetooth module, an
L298N motor driver, and a 16x2 LCD screen. Pet owners can use simple voice
commands like "Feeder Open" and "Feeder Close" to feed
their pets while receiving real-time information via the LCD screen, giving
status updates, such as "Feeder Opening" or "Complete Feed”.
Without the user needing to tap a button on an app that can cause randomisation
in feeding times, the hands-free system ensures consistent feeding without
risking the overfeeding of a pet or underfeeding a pet. The system works in
real-life situations with an average voice recognition success rate of 93.7%.
It dispenses food consistently with a portion variance of ±2%. It has a
response time that is less than 500ms, reliable Bluetooth connectivity of up to
8m, and low hardware costs (estimated at less than $35), making it a much more
economical solution than any commercial solution available today. The project
highlights the usage of embedded systems as part of daily life, bringing
convenience and peace of mind to pet owners. It represents a solid step in
developing more expandable and voice-automated pet care systems that remember
the trade-offs between cost and home automation. Future enhancements may
include Wifi integration, so pet owners can control the feeder remotely via a
mobile app and add a Real-Time Clock (RTC) module for scheduling feeding time.
