-  Turns 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 is set to
-  the correct LED pin independent of which board is 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:
