“I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano. The segments are controlled by 18 MAX7219 ICs which can control up to 64 individual LEDs or 8 ...

In the Arduino board, digital outputs from D2 to D8 are used to drive segments (a to g), and digital outputs D9 to D12 are used for the digits (D0-D3) of the 4×7 LED display. Note that here the ...

[David Hopkins] built a seven segment clock, but not in a way you would think. Typically, if one wants to make something like this, one would start off with some seven segment LEDs. [David] wanted… ...

[Kevin Rye] built a discrete TTL based seven-segment clock, and he wasn’t too happy with the ugly insides compared to the nice enclosure he built for it. He embarked on creating another large… ...
