Second prototype of the Arduino LED time piece. This time is much higher fidelity. I got some nice clear round enclosures from the container store, and customized them to created a really nice feeling container for the project. I used a dremel tool to create openings for power and USB, and sanded the lid down to create a nice diffusing effect. Inside the enclosure, I have an array of 12 LEDs in a circular pattern, grounded in series and connected to power pins on the Arduino individually. They are connected using wire-wrapping and hot glue, a technique that we are learning in class that is really, really convenient for prototyping like this. You can see the various ways that I programmed it in the video.
