Not much yet. I can get it to light/cycle the on board rgb led. I can also connect the on board button to a color (or multiple colors) of the led.

I'm currently trying to work out how to implement some kind of debounce method. Once I get that working, having it cycle led colors on each rising signal from the button.

Knowing what I know now, I should have gone with the single 'chip' version (Upduino) until I was more comfortable with the language.
