• Description:
This is a getting started series for the products found on my online shops!
In this video, we setup a DS3231 real-time clock (a higher precision version of the DS1307) to keep track of time using an Arduino Uno and an ESP32 development board:
amzn.to/3bZLId0
Real-Time Clocks allow us to easily and accurately keep track of seconds, minutes, hours, week, date, month and year information. They're typically used for time-stamping sensor data while it's being logged. Using an external (CR2032 coin cell) battery, the RTC is able to keep tracking time even when it loses power.
