This is an update/refactor of https://github.com/br3ttb/Arduino-PID-Library, since the original library seems pretty much abandoned.
For an explanation of many of the implementation details see the excellent series of posts by the original library author: http:https://brettbeauregard.com/blog/2011/04/improving-the-beginners-pid-introduction/
#include <PID_v2.h>
#define PIN_INPUT 0
#define PIN_OUTPUT 3
// Specify the links and initial tuning parameters
double Kp = 2, Ki = 5, Kd = 1;
PID_v2 myPID(Kp, Ki, Kd, PID::Direct);
void setup() {
myPID.Start(analogRead(PIN_INPUT), // input
0, // current output
100); // setpoint
}
void loop() {
const double input = analogRead(PIN_INPUT);
const double output = myPID.Run(input);
analogWrite(PIN_OUTPUT, output);
}I've added a few things, but code written with the old library should still work
after changing #include line.
