A solar tracking system uses a microcontroller and light dependent resistors (LDRs) to automatically orient a solar panel towards the sun throughout the day. The system includes a microcontroller, motor driver IC, two LDRs, DC motor, and power supply. It works by using the LDRs to sense light levels on both sides of the panel and sending that input to the microcontroller. The microcontroller then controls the motor driver and DC motor to adjust the panel's position accordingly, maximizing exposure to sunlight and boosting the system's efficiency. The document outlines the hardware components, block diagram, and software tools needed to design and implement the microcontroller-based solar tracking system.

Abstract
Renewable energy is rapidly gaining importance as an energy resource as fossil
fuel prices fluctuate. At the educational level, it is therefore critical for engineering and
technology students to have an understanding and appreciation of the technologies
associated with renewable energy. One of the most popular renewable energy sources is
solar energy Moreover, of all the renewable energy sources available, solar energy has
the smallest environmental impacts. Electricity produced from photovoltaic cells does not
result in air or water pollution, deplete natural resources, or endanger animal or human
health.
A Solar tracker is a device for orienting a solar photovoltaic panel towards the
sun. In solar tracking systems the surface of the module tracks the sun automatically
throughout the day. Tracking system increases the efficiency of the system considerably
there by reducing the cost per unit of output energy.
