 *  IMPORTANT: To use this code in Arduino's IDE, first move the Move38-Blinks folder
 *  into the right directory i.e. <user home directory>/Documents/Arduino/hardware/Move38-Blinks
 *  Then open the Arduino IDE and select Tools > Board > "Move38-Blinks"
 *  Now you should be good to go :) (thanks to the hard work of Josh Levine – josh.com)
