2.   Blink
3.   Turns on an LED on for one second, then off for one second, repeatedly.
4.  
5.   Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
6.   it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN takes care
7.   of use the correct LED pin whatever is the board used.
8.   If you want to know what pin the on-board LED is connected to on your Arduino model, check
9.   the Technical Specs of your board  at https://www.arduino.cc/en/Main/Products
10.  
11.   This example code is in the public domain.
