You can dim DC LEDs with a simple pot.
Not very well. What are DC LEDs ? Yoiu don;t need a pot just a
varible resistance will do.
Helpful hint: when you've barely a clue what you're talking about,
don't pretend to be an expert.

He is supposed to teach this sort of stuff,
I DO NOT teach this sort of stuff.
it explains why ARW's apprentii are so bad if teaching is done by
teachers at this level.
You can't even get that right.

Then why not ask ARW apprentices (NOT apprentii) whether they have
degrees from the university of London, if they don't maybe that explains
it.
I knnow far more about it than either of yuo , LEDs are essentail current
drawn devices NOT voltage. Only as complte idiot would think a
potentiometer is the correct way to dim a LED
with a fixed voltage supply, increasing the resistance in a circuit should
lower the current. I think someone called Georg Ohm came up with that idea
