After refamiliarizing myself with the Arduino usage of that library, I realized that the way we have it set up, you need to select the 3pi or one of Orangutan boards in order for the library to be accessible. In general, I don’t recommend using this library with boards other than the 3pi or one of the Orangutan controllers. If you’re using an Arduino Uno or switching to an Arduino Mega 2560 like you mentioned in your other thread, there are probably much more appropriate libraries for your hardware, as Patrick suggested there.
