Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

And we end up seeing all kinds of display techniques being used to show time. For the simplest of builds, 7-segment display modules usually get dug up from the parts bin.

The 7-segment display is taped and set into the back of the 1/4″ pine with enough brightness to shine through the additional layer of veneer on top.

In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...
