Glad it's now working, easy isn't it!!

'Moved it to normal 3.3 v pin'

What was the mode of that ('normal') pin? 'auto' maybe?

getPinMode()

Any GPIO pin will work. So no real need to move away from D25

'driving the 3.3v side of the logic level shifter'

Would you please post a link to the level shifter pinout and schematic, so that we may answer that accurately for you.

Now that everything is working, what are the plans for the visual output. Running tracer, sparkles, random, train sequencer, meteor, color changer? I may have some code snippets I can dig up.

I would love some code snippets ;)

They dont seem to provide the schematic directly but i bought this one

What i mean with the normal 3.3v pin is the pin that always just supplies 3.3v, i dont know how to target that pin through code. I will upload some videos of the application.
