Arduino Real-Time Clock (RTC) Tutorial | DS3231 & DS1307 Timekeeping
Add accurate, battery-backed timekeeping to your Arduino projects with a Real-Time Clock (RTC) module. This tutorial covers the popular DS3231 and DS1307 RTC chips — wiring, libraries, and how to read/display date and time.
🕐 What you'll learn:
• RTC module types and why they matter
• Wiring RTC to Arduino (I2C)
• Reading and formatting date/time data
• Keeping time through power cycles
