This 3D-printed mechanical clock uses three stepper motors controlled by an Arduino Uno and a real-time clock module. Each digit is powered by cam-driven segments with rubber bands helping reset the ...

I attempted to use the code that had been used to drive the simple 4 digit display but that proved to be inadequate. A 7_seg_led_library library was created to bridge the gap between main and the ...

The 7-segment display is taped and set into the back of the 1/4″ pine with enough brightness to shine through the additional layer of veneer on top. The display is set to show one digit and then ...

What do you do with 144 7-segment displays? If you’re [Frugha] you put them all together to create an epic clock. Each display has 8 individual LEDs — 7 segments, and a decimal point. P… ...

By using these driver ICs, the complexity of wiring and control is significantly reduced. “I’ve built a digital clock made out of 144 seven-segment displays controlled by an Arduino Nano.

Maker Michael Klements has built a unique electromechanical clock using a little Arduino hardware, code, and 28 servos, which tilt panels to reveal the correct time in digital format.
