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 ...

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 ...

[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 ...

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.
