Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push button increment of the counter ... Just follow the schematic ...

Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced circuits using multiple seven-segment light emitting diode displays. Here is a simple, yet useful ...

[FilleK] had some time to spare and decided to build a cheaper substitute for a real nixie tube using a regular 7 segment LED display. We have already seen this hack before, in the Arduino-based ...
