+ 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, 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
+
+ This example code is in the public domain.
