Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller, an RTC DS13072 real-time clock module, and a 16x2 I2C LCD display. The circuit is designed to display real-time data on the LCD screen using the RTC module for timekeeping. The Arduino UNO serves as the central controller, interfacing with both the RTC module and the LCD display via I2C communication.
