I use a snippet manager called keep.
It runs in the terminal, and helps remember commands. I use it for remembering commands with lots of flags and parameters that i don’t use often. But it can be used to remember any command you need.
You can also add comments to each command to remind you what it does.
I add the command i need to remember with
keep new
And when i forget it i can run
keep list
To get a list of commands.
It can do more, but i’ve only ever used those two functions.

I’m happy to help.

I don’t know much about WLED, but from the other comments here it would appear so. And i think it’s also what makes the most sense.

If i’m understanding your question, what you’re looking for is Ohm’s law
Amp = watt / volt
1 / 24 = 0.042
You want milliamps, so multiply by 1000 giving you 42mA per IC

Alternative if the first one doesn’t tickle your fancy.
