Über den Serial-Monitor können 3 verschiedene Zustände eingegeben werden. j = LED leuchtet n = LED leuchtet nicht p = LED fadet ein und aus Filmchen der 3 verschiedenen Zustände

#define LED 11                // choose the pin for the LED

byte message = 0;
int brightness = 0;    // how bright the LED is
int fadeAmount = 5;    // how many points to fade the LED by

void setup(){
pinMode(LED, OUTPUT);         // declare LED as output
Serial.begin(9600);           // open serial port @9600baud
}

void loop(){
 if (Serial.available() > 0){  // check for new data in serial port
 message = Serial.read();
 ja();
 nein();
 pause();
}
//}

void ja(){
 if (message == 'j') {       // check if the input is 'j'
 digitalWrite(LED, HIGH);  // switch the LED on
}
}
void nein(){
 if (message == 'n') {       // check if the input is 'n'
 digitalWrite(LED, LOW);  // switch the LED off
}
}

void pause(){
 if (message == 'p'){      // check if the input is 'p'
 for(int x =0;x<=255;x++){
 analogWrite(LED, brightness);

 brightness = brightness +fadeAmount;        //fade in

 if (brightness <= 1 || brightness >= 254) {
 fadeAmount = fadeAmount* -1 ;       //fade out
 }
 delay(30);
}
}
