ESP32 Real Time Clock (RTC) with DS3231 Project

The ESP32 Real Time Clock (RTC) with DS3231 project demonstrates how to use the DS3231 RTC module to keep track of real-time data with high accuracy using an ESP32 microcontroller. This project is ideal for applications that require precise timekeeping, such as data logging, scheduling tasks, and alarms.
