Try to use an Arduino Nano for display a number via WS2812 matrix 16x16

It would be awesome to have the capability to change the scale of the matrix from 16x16 to e.g. 32x32

In software?
You can put four of these together to give you 32 by 32.

Look at the Adafruit graphics libraries for the display.

Which is useless for anyone looking at this on a mobile device, like I am. Please read the how to use this forum sticky post.
