This document describes a sun tracking solar panel system that uses a microcontroller and stepper motor to rotate a solar panel throughout the day to always face the sun and maximize energy generation. It tracks the sun's position using time as a reference to control the motor's movement every 12 hours according to a programmed schedule. The system hardware includes an 8051 microcontroller, solar panel, stepper motor, voltage regulator, and other components. The software is programmed using Keil to control the microcontroller and motor.

3. Introduction
The main objective of this project is to track the sun and rotate the
solar panel accordingly, to receive sunlight to the fullest extent always
during the day time.
This movement is achieved by interfacing a stepper motor to the
solar panel that changes its direction according to the positioning of the
sun.
This is achieved using time reference that controls the movement
time for 12 hours by a program written in such a way that for every
given time the solar panel faces to the sun to generate maximum power
which is stored in batteries and future use.

4. EMBEDDED SYSTEMS
Definition for :- EMBEDDED SYSTEMS
 A combination of hardware and software which together
form a component of a larger machine.
 An example of an embedded system is a microprocessor that
controls an automobile engine.
 An embedded system is designed to run on its own without
human intervention, and may be required to respond to
events in real time.
