Circuit Documentation

Summary

This circuit is designed to interface an Arduino UNO with two Light Dependent Resistor (LDR) modules, a solar cell, and a micro servo motor. The Arduino UNO serves as the central microcontroller, reading data from the LDR modules and controlling the servo motor. The solar cell provides power to the circuit.
