Thanks for the response Mike. Whats the "10" in the 160 * 3 *10 * 300 formula represent?
I think sd card is the way to go like you mentioned, and testing the refresh speed to see if it is feasible. Still looking around on implementing it.
We were going off of this old thread you posted in to help us: Neopixel and SD card - LEDs and Multiplexing - Arduino Forum
using some of your code but we struggled and just a bit in over are heads with implmenting the basics with the sd card. I'll keep looking and trying and learning.
