boolean heater instead of PWM?

[flatsiedatsie]

Can this library drive a boolean heater as well?

Use the AutoPIDRelay class

Is their a sketch example for the AuoPIDRelay function

[dtmutsvanga]

No. The trick is to use a reasonably large value for your "pulse with." Try this:

` //Define Variables we'll be connecting to
double Setpoint, Input, Output, temperature;
double Kp=10, Ki=5, Kd=1;
bool relayState;

AutoPIDRelay myPID(&Input, &Setpoint, &relayState,10000.00,  Kp, Ki, Kd);
// some code

void loop() {
temperature =getTempC();  //refresh temp
myPID.run();
digitalWrite(RELAY_PIN, !relayState);
//do something
}`

Thank's for the quick answer. I will try it straight away.

Hello,

I am trying the AUTOPID Relay and i have a question please if the Pulsewidth value should be fixed in the sketch or it can be changed somewhere else inside the program like the Setpoint for example.

Thank you,

AutoPIDRelay constructor takes pulseWidth as a parameter.
