From Wikipedia: "A PID controller calculates an 'error' value as the difference between a measured [Input] and a desired setpoint. The controller attempts to minimize the error by adjusting [an Output]." So, you tell the PID what to measure (the "Input",) Where you want that measurement...

At long last, I’ve released anAutotune Libraryto compliment theArduino PID Library. When I released the current version of the PID Library, I did an insanely extensiveseries of poststo get people comfortable with what was going on inside. ...
