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 ...

Though [Connor] labels it as a work in progress, we’re pretty impressed with how polished his transparent 7-segment display looks ... if you missed his LCD data transfer hack you should check ...

If we put in the sockets four 7-segments LED common cathode LCD display devices ... board (the common pin) to the Arduino GND signal. At this point, all works fine again, the only difference being ...
