Help getting Blinkt pixels to flash?

Can anyone teach me how to get some of the pixels on my Blinkt to flash? I’m new to this and I’m just trying to make a simple flashing lightbar where some of the pixels flash at different times. Thanks in advance!

The examples are here,

And I do believe if you ran the installer they should be on that Pi in a Pimoroni folder. Pomoroni > Blinkt.
It’s worth playing around with some of those to see what they do versus the code in the file.
The function reference is here
and some tutorials here

This is all linked too from the bottom of this page.

I have one, but to be honest I’ve only ever used it to show CPU temperature or CPU load via the provided code examples.
