Thanks to Pawel Drylenko we now have a working solution to incorporate the Arduino Neopixels with Klipper. We're created shell scripts to make installation easier. SSH into the RPI. Run the following commands:

git clone https://github.com/armysolo/neopixels_in...

cd into the newly created "neopixels_install" directory

cd neopixels_install/

Run the script for step 1

sh neopixel_step_1.sh

When prompted reboot the pi
