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