To implement a PID controller in an Arduino sketch, five parameters must be known: proportional, integral and derivative constants, input value and set point value. Well, let’s start with a crude demo ...

[Brett] sent us a note about his work on the new Arduino PID library. He is the author of ... graphs to show the hurdles each portion of code is meant to overcome.
