The color cycling is caused by dimming and brightening a red, green, and blue LED at different rates. The problem is sometimes by chance they're all bright, other times they're all dim. So in addition to the color cycling, there's pseudo-random luminosity cycling. It's much more annoying in person than it was in the video.

So I took the previous code and adjusted it to maintain a reasonably constant brightness level.

It was mostly just 4 lines:

float sum = redVal + greenVal + blueVal;

int adjRedVal = (float)redVal/sum * targetBrightness;

int adjGreenVal = (float)greenVal/sum * targetBrightness;

int adjBlueVal = (float)blueVal/sum * targetBrightness;

If I was actually going to leave it going rather than just playing around with it, I'd slow down the cycling too.

Arduino basics by Cory Forsyth

Got the arduino's inline LED blinking...the hello world of hardware.

Some notes for myself about a mini arty/led-y project I want to build:

* Extend the number of output pins on the arduino using a shift register (http://www.arduino.cc/en/Tutorial/ShiftOut)

* sparkfun is a good place to buy

* I need to get a breadboard, a soldering iron, a bunch of leds, a 595 for the shift register
