The Solar Tracking System with Arduino is a smart and efficient solution designed to enhance the energy harvesting capabilities of solar panels. By employing sensors and an Arduino microcontroller, this system ensures that solar panels are optimally aligned with the sun throughout the day, maximizing energy output.At the heart of the system is the Arduino microcontroller, which acts as the brain, receiving input from light sensors or other tracking mechanisms. These sensors constantly monitor the intensity of sunlight and communicate with the Arduino to determine the sun's position. Based on this information, the Arduino then adjusts the orientation of the solar panels to directly face the sun, ensuring that they capture sunlight at the most favorable angle.This dynamic solar tracking feature significantly improves energy efficiency compared to fixed solar panels. By continuously aligning with the sun's position, the system harnesses more sunlight, leading to increased power generation and greater overall energy output. The Solar Tracking System with Arduino is not only a cost-effective solution but also a sustainable one, as it harnesses solar energy more efficiently, making it an ideal choice for applications such as solar-powered water pumps, solar tracking farms, and other renewable energy systems. The use of Arduino technology makes it accessible for hobbyists and professionals alike, contributing to the widespread adoption of intelligent solar tracking solutions for a greener and more sustainable future.
