   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://arduino.cc
+
   This example code is in the public domain.
