This study aims to design and implement an automatic solar tracking system using an Arduino Uno microcontroller, Light Dependent Resistor (LDR) sensors, and servo motors. The system enables solar panels to dynamically track the sun's position to optimize energy absorption. Four LDR sensors detect light intensity from various directions, providing real-time feedback to the microcontroller, which controls two servo motors to adjust the panel's angle. Experimental results indicate a potential 30–40% increase in power efficiency compared to static panels. The system is energy-efficient, cost-effective, and well-suited for tropical regions with consistent sunlight exposure.
