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 ...

By using these driver ICs, the complexity of wiring and control is significantly reduced. “I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano.

We love the way this clock celebrates the seven-segment display, and only wish it were much bigger. The STLs and code are available if you want to make one, though they only cover the 7-segment ...
