LED cubes are fascinating. The allure of blinking LEDs in various patterns is always attractive and mesmerizing. Like many Arduino fans there came a point when I decided I would try my hand at one (or two, as it turned out).
Whilst they look complex, they are, in principle, relatively straightforward from an electronics and software perspective. Making the cube can be challenging, but by using jigs and patience, this becomes more of a chore than a challenge!
