After all the effort to get up to meet the DorkbotPDX crowd, I figured I should do something (non-train related) with the Dorkboards we came home with.
There are six LEDs attached to the pulse-width modulation capable pins. They fade in and out at random times and rates, and will continue flashing for ten minutes after the lights go out.
I got the idea from an Instructable where they put them in a jar and used a much smaller chip like I used in Project Buggy. The Arduino makes it much easier to build and program a project like this.
