Larson scanner using Port Manipulation

KIT / Battlestar Galactica Cylon scanner effect

Courtesy/Thanks to: Code by Runaway Pancake

Description: This is a simple project using code made by Runaway Pancake over at Arduino forum. He came up with an idea of "poking" or using Port Manipulation to get the trailing effect which is very important for a true Larson scanner effect. See the video on how to build a small footprint Arduino Larson scanner. The code used is the same as on the Arduino forum (link to the right).
