Programmer needed to make changes to existing code for running WS2812B LED's with arduino

I'm using an arduino uno to display text on WS2812B LED strips in a matrix. In the final setup I might have 7 strips of around 210leds = 1470leds. Currently I have them working nicely with this code from github, hardware-wise mine are set up in the same fashion:

I need someone to make changes to the code:

-I would like text to be displayed static (not scrolling) for a definable amount of time

-A definable small pause with blank leds then another line of text should be shown

-Example of lines, all are around the same length:

Diego dogme råskene svolke

edelig kovene skogsområde

kosende skoleråd voggemei

doggene kvise skoleområde

-not crucial: If possible the next displayed text-line should be chosen at random (from 10k

possible lines)

-not crucial: Great if one could also randomize the colour each time a new line of text is

shown

All the lines that will be shown totals around 10000 lines, in a .txt it totals around 279kb.

This is to much to store in an arduino uno, but if we cut down to say 6000-7000 lines maybe it

could work on an ATmega2560? Otherwise maybe one could make it work reading from an sd card

shield?

If this is difficult to to achive with arudino I'm open for sugestions, but as this should be able to run for years without much supervision I imagine arduino is a good choice for stability. Otherwise maybe using a raspberry pi?

Hello. I have experience with WS28XX leds. Your case could be solved using arduino uno or nano with connected micro sd card with your txt files. It will work stable. Randomizing output it’s not a problem. I will resear Flere

The last project I made was to drive sk6812 LED strip using hardware timer so that the program runs in the background and doesn't consume CPU. For your project I wouldn't use hardware timer though. I think the Atmeg Flere
