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 ...

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. The display is set to show one digit and then ...

It uses two rows of seven-segment displays to show the current operation and the results. Programming the Arduino Nano to work as an RPN calculator involved a few tricks, though.

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 ...

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.
