I probably deserve this, but it has me confused.
I killed a machine the other night, and had to rebuild it.
It isn't complicated for hardware, but I am getting a strange error.
Setup - hardware:
RasPi 3b Buster.
NeoPixel strip of LEDs.
Level converter for LEDs.
Flow - breakdown:
Sets LEDs per what is happening.
To the best of my knowledge I installed all the same nodes.
I have the node-red-node-pi-neopixel and node-red-node-pi-gpio installed - latest versions.
Though it kind of gets me it is pi-gpio and there is an error about rpi_ws2801x is referenced below.
This is what I see when I start Node-Red:
Note last couple of lines.
pi@MusicPi:~/.node-red$ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.0.82:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org
Starting as a systemd service.

Sorry folks. This should be simple.
It did work. I just seem to be missing a node, but I can't resolve the name from that error.
