Graham’s word clock is controlled by an arduino and a piece of open-source software that allowed him to code the clock once he found the appropriate code online.

Behind the clock is an Arduino driving a MAX7219 LED controller. Using the MAX7219 was a challenge because it expects a grid of LEDs while the clock needs a linear array.

Sick of telling time the old way? Spice up your time-telling time with the open-source, hackable and Arduino-based DOTKLOK. Basically, you can get a bunch of different ways to tell time. Different ...

For [Yasa], it was learning 3D modeling combined with a little trip down memory lane that led him to create a fully functional word clock as a rendered animation in Blender.

Check out this smart shelving system driven by an Arduino and using LEDs, which serves as a clock.
