Pi 5V to LED 5V

Pi GND to LED GND

Pi GPIO18 to LED Din

On the Raspberry Pi, NeoPixels must be connected to

GPIO10, GPIO12, GPIO18 or GPIO21 to work!

CircuitPython Installation of NeoPixel Library

You'll need to install the Adafruit CircuitPython NeoPixel (https://adafru.it/yew) library on your CircuitPython board.

First make sure you are running the latest version of Adafruit CircuitPython (https://adafru.it/Amd) for your board.

Next you'll need to install the necessary libraries to use the hardware--carefully follow the steps to find and install these

libraries from Adafruit's CircuitPython library bundle (https://adafru.it/uap). Our CircuitPython starter guide has a great

page on how to install the library bundle (https://adafru.it/ABU).

For non-express boards like the Trinket M0 or Gemma M0, you'll need to manually install the necessary libraries from

the bundle:

neopixel.mpy

adafruit_bus_device

Before continuing make sure your board's lib folder or root filesystem has the neopixel.mpy, and

adafruit_bus_device files and folders copied over.

Next connect to the board's serial REPL (https://adafru.it/Awz) so you are at the CircuitPython >>> prompt.
