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 is set to
7  the correct LED pin independent of which board  is 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
