User Guide / How to Use

To use the dual axis solar tracker, place the system in an open area with direct sunlight. The Arduino Uno receives input from the four LDR sensors and controls the MG90s servo motors to adjust the solar panel’s angle. When sunlight is available, the tracker automatically positions the panel for maximum light exposure. During daylight, the charging indicator LED remains ON, while the home light remains OFF. When no sunlight is detected, the COB LED automatically switches ON, providing night-time illumination. Recharge the lithium-ion batteries using the provided Type-C charger for continuous operation.
