Another update on my experience with these lights.
The above code worked to control the strip - thanks blip!
- And the lights are MUCH brighter than I thought they would be.
I am not sure if this is a suggested use for the pixel / dome LEDs but I was able to get the 8mm and 20mm (5v) and the dome (12v version) all working together with only 2 pins total (daisy chained).
Of course only the data wires (yellow/green) were daisy chained to the 12v dome, which gets it's own 12v power. The 20mm and 8mm could be daisy chained naturally, power and all.
While all three of these LEDs have different RGB orders, the chips appear to be same and the daily chaining worked great.
I can't say enough good things about my first experience with the sample selection ordered. Thanks for the "out of box" solutions for individually controllable rgbs - this is the holy grail and testing shows it is a reality!
