Description
Automatic Solar Tracking System Using Arduino and LDR Sensors is a renewable-energy-based project designed to automatically orient solar panels toward the direction of maximum available light. The system uses light-dependent sensors to measure light intensity from different directions. A microcontroller processes these sensor readings and controls a motor through a motor-driver circuit. When a difference in light intensity is detected, the motor adjusts the position of the solar-panel assembly toward the brighter direction. This process allows the panel to maintain better alignment with the sunlight throughout the day. The project demonstrates the integration of solar energy, sensors, microcontrollers, motor control and mechanical automation.
