  Blink

  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 and

  Leonardo, it is attached to digital pin 13. If you're unsure what

  pin the on-board LED is connected to on your Arduino model, check

  the documentation at http://www.arduino.cc


  This example code is in the public domain.
