unsigned long event = 5000;// 5 seconds

  Serial.begin(9600);//initialize serial monitor
  Serial.println("Introduction to millis");
  pinMode(2,INPUT_PULLUP);
 
}

void loop() {
  // Robojax.com millis() example 1
  Serial.println(millis());

  {
      if(millis() >= event)
      {
        Serial.println("Take action");
      }// if end
  }// if end
  
}// loop end
