Appendix F. Arduino Pin and Timer Usage

The tables in this section show the pin and timer resources used by the projects in this book. You can use the same pin assignments for the Leonardo boards or the standard ATmega328 boards such as the Uno. However, there are subtle low level differences between these boards, so if you are adding capabilities that use additional pins or resources beyond those described in this book, then check the documentation on pin and resource usage for your board.

Handling Resource Conflicts

The Arduino chip has a rich collection of hardware resources, but you can run up against a conflict if a feature you are adding requires a hardware resource that some other feature is already using. A resource conflict occurs when ...
