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 ...

This seven segment art display makes use of a 81 seven segment red common cathode LED displays. The LEDs are arranged onto 100x100mm boards that each contain an Arduino Nano and 9 seven segment dis… ...

If you need a seven-segment display for a project, you could just grab some LED units off the shelf. Or you could build something big and electromechanical out of Lego. That’s precisely what ...

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.
