  Blink without Delay



  Turns on and off a light emitting diode (LED) connected to a digital pin,

  without using the delay() function. This means that other code can run at the

  same time without being interrupted by the LED code.



  The circuit:

  - Use the onboard LED.

  - Note: 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:
