Virtual Color Mixer

This example demonstrates how to send multiple values from the Arduino board to the computer. The readings from three potentiometers are used to set the red, green, and blue components of the background color of a Processing sketch.

Building A 16×32 NeoPixel Display

Earlier this year while attending a FabNow Conferance in Ft. Worth I came across a few exibits with Neo Pixel Rings. I was fascinated with the color levels and the fact they could be controlled with a single wire!

Visualizing Music With FFT

The following videos are displaying patterns generated by a Processing program doing real-time FFT (Fast Fourier transform). Basically it is visualizing music in the frequency domain using a polar-coordinate particle system.

NeoPixel 16 Ring Fun

NeoPixels are fun and amazing. In my project I connected 4 of the AdaFruit NeoPixel – 16 RGBW Leds together. What caught my attention and curiosity was that you can control each of these RGBW Leds using just one wire.This feat is accomplished with a very timing-specific protocol. Since the protocol
