I'm using a knockoff uno sensor shield v5. I noticed tonight that it has pins labeled URF01 and looking at the manual it says theses pins are for the ultrasonic sensor. Which is great because I'm using one of those. My problem is how do I refer to them in the sketch? The manual has the pins listed as URF01-A0 and URF01-A1.

So my questions are, are these pins separate from the analog pins that are also on the shield and if they are separate how do I call them in the sketch? I've googled and searched the forum and I can't really find an answer. I've attached an image of the board from the manual so people have some idea of what I'm talking about.

They don't seem to be separate; you can easily check that with a multimeter.

Looking at the picture, that interface uses pins A0 and A1.

Note that there is nothing special about those pins except that they can be used as analogue inputs; this does not add value for use with e.g. a HC-SR04.
