Summary of the Circuit

This circuit integrates an Arduino UNO microcontroller with a servo motor, a real-time clock (RTC) module, and a 16x2 I2C LCD display. The Arduino UNO serves as the central processing unit, controlling the servo motor and communicating with the RTC module and the LCD display via I2C protocol. The servo motor is controlled through a PWM signal from the Arduino. The RTC module provides timekeeping functionality, and the LCD display offers a user interface for displaying information. Power distribution is managed through common 5V and GND connections from the Arduino to the other components.
