LED
===

The MetaWear board comes with a builtin RGB LED, encapsulated with the `MBLLED <http://mbientlab.com/docs/metawear/ios/latest/Classes/MBLLED.html>`_ object.

Set Color
---------

This snippet will set the LED to a solid red color.

::

    device.led?.setLEDColorAsync(.red, withIntensity: 1.0)

Flash Color
-----------

This snippet will flash the LED a red color indefinitely.

::

    device.led?.flashColorAsync(.red, withIntensity: 1.0)

Or you might find it beneficial to flash only a few times.

::

    device.led?.flashColorAsync(.red, withIntensity: 1.0, numberOfFlashes: 3)

Turning Off
-----------

This snippet will completely shut down the LED.

::

    device.led?.setLEDOnAsync(false, withOptions: 1)
