Circuit Documentation

Summary

This document provides a detailed overview of a circuit that includes an ESP32 microcontroller, a Servo motor, and an RTC DS3231 module. The ESP32 serves as the central controller, interfacing with the Servo motor and the RTC module to perform various tasks. The Servo motor is controlled via a pulse signal from the ESP32, while the RTC module provides accurate timekeeping.
