Dual Axis Solar Tracker with Arduino and LDR

Arduino Based Dual Axis Solar Panel Tracking System This science project is a dual axis solar tracker designed with Arduino Uno and LDR sensors. It automatically adjusts the solar panel position both horizontally and vertically using two MG90s servo motors to capture maximum sunlight. The project also includes an automatic day-night control system with LED indicators, making it an ideal educational and DIY project for students and solar enthusiasts.
