The Chronos time keeping shield for Arduino.

The ideal shield to start experimenting with making your own clocks! or to start experimenting with Arduino in general.

This shield includes a 4 digit 7-segment display with dots for time and degrees; so almost any number format can be displayed on the display. The segments of the display are wired to a 595 shift register as such all segments can be controlled as the user wishes. So not only can you show numbers and time, you can also show your own defined shapes!

Why did you make it? The circuit on the shield was originally made as part of a larger circuit and built as a unit to be incorporated in a larger project. But since the circuit was quite easy to use and universal, we decided to release it as a stand-alone circuit. As such the Chronos shield for Arduino was born!

What makes it special? It is a very simple and easy to understand circuit! But it is even easier to use this circuit! This makes it ideal for prototyping and learning.

When you are done prototyping, the shield with an Arduino can be easily built into a case to make a nice clock!

The shield comes with a CR2032 battery holder meaning that the onboard DS3231 IC can keep the time for a really long time.
