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.

Here is the circuit diagram of a compact RTC module, based on the popular RTC IC DS1307, for your everyday microcontroller projects. The DS1307 serial real-time clock (RTC) is a lowpower, full ...

The RTC module is crucial for keeping accurate time, even when the Arduino is powered off. It maintains the time using a small battery, ensuring that the clock remains accurate.

There’s an Arduino coupled with an RTC module to keep the time, which is connected to the two standard hobby servos mounted in the front panel.
