Tell us about yourself!
Hi Rob, would you paste your code?I want to switch my arduino, too.
Thanks for your instructable ;)After i realized that i shorted the sdl and scl line it works like a charm.I've found a bug in your arduino script.You can't use integer for the ledcolor, you have to use longinteger. Else your unable to use the red color.Also i added some lines to use different colors at different times of day.regards Martin
