Recently I built a one-off serial Arduino with a CC2500 for someone wanting to control a couple of LivingColors and through an external system.
This is what Patrice has built with it. It seems like a big setup (compared to most Arduino projects) and I’m pleased it works.

Nice setup !
The serial Arduino is useful if you want to control LivingColors lamps from a system without USB.
