Ever thought about how the screen on your phone or ipad can show millions of colors? LEDs Blend is an interactive tool for learning to blend colors with light. Each cube represent a color in the RGB spectrum. Just change the intensity of the cubes with the knobs and see how they blend!
Each cube runs a wireless rfduino, a battery and a circuit with a LED array. To have maximum intensity it has two independent circuits, one for the rfduino(3.3V) and one for the lights(5V).
