"""
Blink example for boards with ONLY a NeoPixel LED (e.g. without a built-in red LED).
Includes QT Py and various Trinkeys.

Requires two libraries from the Adafruit CircuitPython Library Bundle. Download the bundle
from circuitpython.org/libraries and copy the following files to your CIRCUITPY/lib folder:
* neopixel.mpy
* adafruit_pypixelbuf.mpy

Once the libraries are copied, save this file as code.py to your CIRCUITPY drive to run it.
