Here is a simple, yet useful circuit of an Arduino 4-digit 7-segment LED display unit. The module used here is a self-contained, compact common-cathode module containing four 7-segment LED numeric ...

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 ...

[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 ...

If you have a bunch of “smart” LED’s (WS2812’s, APA102’s), then building your own custom 7-segment modules isn ... is pretty plain vanilla — an Arduino Nano clone, a DS3231 RTC ...
