How to use iPad as presenter for MacBook?

Question

If I have a MacBook connected to a projector, how do I use my iPad as the presenter for slide switching?

There are solutions for using Keynote here

But how do I do it just with PDF slides?

Answer 1

I think you're asking about remotely controlling your iPad which is plugged in to a monitor.

The simplest solution in my opinion would be a bluetooth keyboard.

If you're trying to remote control your Macbook from the iPad you could use Astropad, teamviewer or similar application.

Answer 2

It might be easier just to get a presentation remote device and forego the iPad. Exactly what utility does the iPad provide in this situation that an inexpensive device can't?
