โปรเจกต์ Studio Prop Wall LEDs

Ok, so needing a bit of help with the coding on this project.

I have 2 current codes:

1. An LED lit sign that runs a scrolling rainbow effect.

2. Plus 2 large resin sword props as you see exampled in the pic. (They pulse a slow fade)

Both codes run great as independent projects. Both are using the same type of adafruit neopixel leds. The swords have mini boards that are battery powered so that they work in-hand, and the sign is wired to an adafruit metro board.

I'm going to post both independent codes - as well as my in-progress merged version... That's where I need the help. I'd like to run both of of the same metro board while mounted on our wall. I can't for the life of me figure out how to get each code loop to run off of different data pins on the board. (I have a VERY basic knowledge with writing these scripts, very basic) I've tried researching, but seem to get even more lost... If someone could help straighten this out for me I'd GREATLY appreciate it!!!

Hardwiring everything and managing that portion is more so my forte. There I have no issues.

Thanks!
