/*
 * Measuring Stick - a quick tool for measuring out 64-LED strips.
 *
 * This is a TeensyDuino sketch which lights the first 64 LEDs
 * on a strip. LEDs 0, 10, 20, 30, 40, 50, and 60 are green,
 * the others are dim white. The entire strip is kept dim enough
 * that this can be used as a battery-powered device that you can
 * plug into LED strips while you work with them.
