What do you do with 144 7-segment displays ... This presented a problem, as [Frugha] wanted to control the clock with a single Arduino Nano. Even charlieplexing won’t get you that many I ...

[David Hopkins] built a seven segment clock ... The easy part consists of Neopixels, an Arduino Nano and a DS3231 Real Time Clock. The hard part consists of Plasticard and a polymorph diffuser.

“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano ... and wiring diagrams to help you get started. One of the key challenges in this project ...

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 ...
