RTC and port expander for an Arduino nixie clock

Luca is designing a nixie clock that will be run from an Arduino. In the latest development he shows to to implement a real time clock source and a port expander to drive the nixies.

In this third blog post, I’m going to show you the logical view of my Nixie clock and two of its main elements: the real time clock, to keep track of the current time, and the expander, to add more I/O lines.
