The DS3231 RTC module operates at 3.3V. It's essential to use a level shifter or voltage divider if you're using a 5V Arduino to interface with the 3.3V DS3231 module. This is a basic example of ...

Set an alarm on the DS3231 clock. Enable the Arduino's main loop to ignore the clock while it performs other tasks. When the alarm happens, the DS3231 will pull the Arduino pin "low", that is, to near ...

This Arduino based Real time clock is a digital clock to display real time using a RTC IC DS1307 which works on I2C protocol. Real time clock means it runs even after power failure. When power is ...

Macetech’s ChronoDot is a Real Time Clock module for projects requiring highly accurate time keeping and measurement. The ChronoDot uses the DS3231 chip, which features a TCXO to compensate f… ...

By adding an Arduino compatible board, an RTC Arduino module, and a code from the EasyNixie library, users can create their own nixie clocks with relative ease.
