Circuit Documentation

Summary

This circuit consists of an Arduino UNO microcontroller and a DS1307 Real-Time Clock (RTC) module. The Arduino UNO serves as the main control unit, while the DS1307 RTC provides accurate timekeeping functionality. The two components are connected via I2C communication, utilizing the SDA and SCL pins for data transfer. The circuit is powered by a common 5V supply, and both components share a common ground.
