Module 24 // Automated Feeding Systems

Smart Pet Feeder

Integrates RTC timing configurations and servo motor control logic to trigger food dispensing actions when scheduled feeding intervals narrow down. The Arduino automatically rotates the feeder mechanism at fixed times and dispenses measured quantities of food.
