Device Independent Control for LED Cubes

LED Cube 8x8x8

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!

TCS230/TCS3200 Sensor Calibration

The TCS230 (and equivalent TCS3200) sensor can be easily purchased mounted on any number of inexpensive breakout boards, similar in design to that shown in the photo. These boards extend the package connections to header pins, and integrate LEDs for illumination of the target object. These sensors work well to recognize color but they need to be calibrated. An Arduino library for this sensor can be found at my Arduino Library site and elsewhere.
