It's fairly common for users dabbling with bare microcontroller chips (e.g. "Arduino on a breadboard") to think that they can pass either the port/bit pin notation (e.g. PB5) or physical chip pin numbers to the Arduino IO functions. These changes are intended to emphasize that these functions only accept Arduino pin numbers as their pin parameter, without complicating the documentation for the users of standard Arduino boards.

I'd like to eventually add a simple explanation of Arduino pin numbers to the "Digital Pins" tutorial, and perhaps the "Analog Pins" tutorial as well.
