This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

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 ...

Reddit user Krukerfluk has created an awesome DIY digital clock using 144 x seven segment displays, combining them to create a larger LED display powered by an Arduino Nano. The small Arduino ...

What do you do with 144 7-segment displays? If you’re [Frugha] you ... as [Frugha] wanted to control the clock with a single Arduino Nano. Even charlieplexing won’t get you that many I/O ...

This is what it looks like in action: My model uses the car's OBD-II port to connect to an Arduino microcontroller, which is programmed to display the car's speed on a 7-segment display.
