Summary

This circuit involves an Arduino UNO microcontroller, multiple Light Dependent Resistors (LDRs), resistors, servos, and a 12V battery. The circuit is designed to read light intensity using LDRs and control servos based on the readings. The Arduino UNO serves as the central controller, processing the input from the LDRs and driving the servos accordingly.
