PIC microcontroller has a native USB interface you can run it easily by adding Open Source Framework for PIC18F USB. Probably most fun part is a host application that is written in Visual Studio C# 2010 and runs under Windows 7. To display UV information on LEDs you actually need to track music information. This is done by using another API that can do lots of thing with music information. Everything is wrapped in to nice GUI where you are able to select several parameters like damping speed, fade OFF speed and colors. Final effect looks really great – worth trying.
