 * Original code and library from - http://arcfn.com

 * Lesson 101: 
 * This code decodes keys for Black IR remotes and White IR remotes
 * sold on eBay for Arduino. 
 * You have to select the type of your remote as Black or White in the code below
 * and also select your receiver 1838 either as PCB or bare module. See video for details
