Arduino-Lantern / Cylon
I had to do this. Partially because I could, but also partially because I needed a quick project. I hadn't done many projects recently (well, summer, duh) and I needed to do something easy with some real impact. Even if I wasn't sure who in the neighborhood would get the joke. I live in the 'burbs - a lot of non-geeks out here. I decided to do some real soldering on this one. I wanted to create a unit I could keep for later if I wanted to use it. I started with a pile o f red LED's I had liberated from a set of Christmas lights. Many of these LED's came pre-equipped with their own resistor. I'm not entirely sure why, though I've noticed during my forays with the RGB LEDs that the red typically wanted lower voltage. I settled on 12 because its what I could comfortably fit in a Radio Shack proto-board. The LEDs with the resistor seemed okay with the 5 volts the Arduino put out without having issues, but the remaining non-resistored ones were rather bright oth
