This single digit display is an old edge-lit module that ... [Ty] laid out his circuit board so that each LED was in the same position as the bulb it was replacing. As you can see, his retrofit ...

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 ...
