How to use multiple WS2812B LED-stripes?

Hi there,

I wanted to use multiple WS2812B LED-stripes.

I have found this project:

But it uses the Teensy 3.x. Does anyone know what additional hardware I need and how to plug in what pins in order to run multiple stripes? Also, does anyone know the maximum number of stripes I can use with an Arduino Uno?

Thanks in advance.

Regards
