8  Turns an LED on for one second, then off for one second, repeatedly.

10  Most  Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
11  it  is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
12  the  correct LED pin independent of which board is used.
13  If you want to know what  pin the on-board LED is connected to on your Arduino
14  model, check the Technical  Specs of your board at:
