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 ...

This time [jegatheesan.soundarapandian] is making it big by building a giant 7 feet tall 7-segment display. Apparently, the plan is to build a giant clock so he started off by making the first digit.
