Data and power signals flow around the cube via solder connections along the edges of the faces of the cube. Running the show is an ATmega328P, the same microcontroller you’d find in an Arduino Uno.

Following are the conversion formulas from RGB to YUV and from YUV to RGB. See YUV and color space conversion. From RGB to YUV Y = 0.299R + 0.587G + 0.114B U = 0.492 (B-Y) V = 0.877 (R-Y ...

After all, the amount of work scales as the cube of the number of LEDs you want each side to have, and let’s face it – with LED ... His LED cubes use discrete RGB LEDs, the kind with four ...
