Can someone please explain the process of the Loop back test a bit more. I cant seem to get any Arduino project right and I am starting to think its the Arduino since the projects without an Arduino I am completing just fine. It says connect to terminal application. If I have Windows is that a CMD prompt or specific program within windows? If someone could please explain this part of the guide it would be very much appreciated. Or any links to where this techgnique would be. Tried looking and not having much luck.
This is the Loop Back Test I need the help with. http://forum.arduino.cc/index.php?topic=73748.0
My son and I are both getting frustrated so any help would be awesome. Thanks.
