Light Painting | RGB LED Wand First Run

Lately I have been working on a few arduino controlled light painting tools and recently took the first prototype out for a bit of painting in Austin.

A more detailed post about the wand will follow, but a bit of info for the curious. It consists of a 4 lead common cathode RGB LED strip controlled by an RBBB Arduino clone and “driven” with a uln2003 darlington array IC. 4 potentiometers make up a simple UI that controls the multiple mode selection, color and time values for the operational modes. This first version just had three modes programmed for this outing: solid color mixer, time controllable dashed color mixer, and time controllable rainbow fade. Runs on 12v.
