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.

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… ...
