RGB LED Smooth Colour Transitions

RGB_WidgetThis is a yet another contribution to the already extensive literature that surrounds RGB LEDs and changing colors, but in all my research I have not seen the method I have implemented, so here it is in case someone else can use it or similar algorithm.

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.
