[jokester4u]

I got an error after placing PId library file Its say \Arduino\libraries\PID_v1\PID_v1.cpp:8:22: fatal error: WProgram.h: No such file or directory

Please someone could help me regarding this problem

The code im running

#include <PID_v1.h>

//Define Variables we'll be connecting to
double Setpoint, Input, Output;

//Specify the links and initial tuning parameters
PID myPID(&Input, &Output, &Setpoint,2,5,1, DIRECT);

void setup()
{
  //initialize the variables we're linked to
  Input = analogRead(0);
  Setpoint = 100;

  //turn the PID on
  myPID.SetMode(AUTOMATIC);
}

void loop()
{
  Input = analogRead(0);
  myPID.Compute();
  analogWrite(3,Output);
}
