I ordered supplies for another project: I’m going to build a set of microcontroller-driven Christmas-tree lights. Each light will incorporate a miniaturized version of the controller I used on the Shame Project, which will drive a standard (low-power) LED. It will run the same evolving rhythm pattern generator algorithm, but I’m going to tweak the color selector: the colors will be fully saturated and limited to the range from red to green. That is, the lights will use reds, oranges, yellows, and greens in varying brightness, but no blue, white, pink, or purple.
