 // lowest and highest sensor readings:
 const int sensorMin = 0;     // sensor minimum
 const int sensorMax = 1024;  // sensor maximum
 void setup() {
  // initialize serial communication @ 9600 baud:
  Serial.begin(9600);  
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
  }
 
 void loop()
  // read the sensor on analog A0:
  {int sensorReading = analogRead(A0);
  // map the sensor range (four options):
  // ex: 'long int map(long int, long int, long int, long int, long int)'
  int range = map(sensorReading, sensorMin, sensorMax, 0, 3);
  
  
  // range value:
  switch (range) {
  case 1:    // A fire closer than 5cm away.
    Serial.println("Close Fire");
    digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
    delay(1000); // wait for a second
    break;
  case 2:    // No fire detected.
    Serial.println("No Fire");
    digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
    delay(1000); // wait for a second
    break;
  }
 }






'''Ergebnis:'''


LED ist aus, wenn keine Flamme in der Nähe ist und "No Fire" erscheint auf dem Bildschirm.
