  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO 
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN takes care 
  of use the correct LED pin whatever is the board used.
  If you want to know what pin the on-board LED is connected to on your Arduino model, check
  the Technical Specs of your board  at https://www.arduino.cc/en/Main/Products

 24-02-2017 http://nettigo.pl Fixes to get it working on current Arduino IDE  based on work:
 3-2-2011 Spark Fun Electronics 2011 Nathan Seidle

 Not all options are working. For sure works: Hello World, change background black/white, 
 Dull boy,both barcode examples and bitmap.
 
 
 To use this example code, attach
