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 ...

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 ...

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 ...
