Abstract
This research focuses on the development and implementation of a solar-powered automatic fish feeder using Arduino and a microcontroller to optimize feeding processes in aquaculture systems. The primary objective is to create an efficient and effective prototype that improves fish farming productivity while aligning with the Sustainable Development Goals (SDGs). The system integrates photovoltaic panels, a 12V 40Ah battery, and a 200W solar panel, controlled by a solar charge controller to ensure continuous, sustainable energy. The Arduino microcontroller serves as the central processing unit, programmed to operate a servo motor that opens and closes the feed channel at precise intervals, dispensing 3kg of feed per day. The feeder operates on two feeding schedules: 8:30–9:00 AM and 3:30–4:00 PM, each involving three cycles with 1-minute intervals to ensure efficient consumption of feed. By utilizing solar power, the system contributes to SDG 7 (Affordable and Clean Energy) and SDG 13 (Climate Action), while promoting sustainable aquaculture practices that support SDG 14 (Life Below Water). The design also aims to improve food security (SDG 2: Zero Hunger) and provide technological innovation in fisheries (SDG 9: Industry, Innovation, and Infrastructure).This solar-powered fish feeder represents a practical solution for enhancing the productivity and sustainability of aquaculture, offering a low-cost, eco-friendly alternative to traditional feeding methods.
