PaulS:
Confusing IMHO, I always use A0-A5 to be clear.
The A0 to A5 aliases were meant to be used when the analog pin is used as a digital pin. In my opinion, analogRead(A0) is MORE confusing. It makes it appear that the user doesn't really know what pin to use.
Not that that applies to you, but some others, I'm not so sure about.
Different horses I guess. I probably use A0-A5 since those are the labels on the Uno board. My preference would be one pin, one name. But that's the nice thing about standards, there are so many to choose from.
//pick one, they're all the same:
analogRead(A2);
analogRead(16);
analogRead(2);
