is the middle pin the gate

No it is the drain.
Look at the data sheet, the last page.
Lay it flat on its back with the hole at the top.
Left pin Gate
Middle pin drain

Whats the IRL234N and how does it connect up


IRLZ34N - that's a Z not a 2!

Hi Nick

How many k or ohms the resistors worth

AWOL

How many does it say on the diagram?

Hey

Check the schematic on page 1

GaryP

Components are named, which one is the problem? R1 could be missing something, maybe author would check the correct value. Or it could be just 10.

Bobby,
Be more specific with your questions.

It's 10 ohms.

10 on its own is 10. (What do you think it meant?) If you go 10 meters that is 10 meters. If you go 10K meters that's 10 kilometers. It's pretty straight-forwards.

Let me ask you a question. R2 is labelled 10K. Do you think that is 10K ohms? Or if not, what do you think it is? I'm interested.
