const int buttonPin = 2;     

const int ledPin =  11;

int buttonState = LOW;
int  lastReading = LOW;
long onTime = 0;

void setup() {
  pinMode(ledPin, OUTPUT);     
  pinMode(buttonPin, INPUT);     
}

void loop(){
  buttonState = digitalRead(buttonPin);

if (buttonState == HIGH && lastReading == LOW) {
    onTime = millis();
  }

//held
  if (buttonState == HIGH && lastReading == HIGH) {
    if ((millis() - onTime) > 3000 ) { //(current time - first pressed time) must be greater than 3000 (3 seconds)
       digitalWrite(ledPin, HIGH);
       lastReading = LOW; //reset state
    }
 
  else {
    digitalWrite(ledPin, LOW);
    }
  }
  lastReading = buttonState; //write button to lastreading for compare
}




I can not try this myself right now, but it should work.

your code works!!! i already tried it.
but my code also works as i add x = 0 in the else statement. anyway thank you.
