Hey, apologies for any bad assumptions, this is my first time messing around with this sort of thing on my own and I'm out of my comfort zone on this one.
I want to be able to selectively power an element that takes 5v, using what I think should be a PNP transistor to switch it on and off. With a Raspberry Pi 4B, I believe the setup should look like this:

Wiring it like that, what I'd need to power the element is a "HIGH" output from GPIO-18, and a "LOW" output to switch it off. While I don't know the specifics of the transistor I have, from what I've looked at online it seems like this might work.
I wanted to check if any of this is correct, as I'm kind of nervous about wiring my own experiments still.
