11.- Virtual Screen with two VerticalArrangement.

In this example I have used Send1ByteNumber, I have arbitrarily chosen the numbers 153,168,221.
Arduino returns a byte 48 or 49.

#define LED13 13
byte StatusLED13;

void setup()
{
  Serial.begin(9600);
  pinMode(LED13, OUTPUT);
}

void loop() { 
  if(Serial.available())
  {
    int dato = Serial.read();
    if(dato == 153){digitalWrite(LED13, HIGH);}
    if(dato == 168){digitalWrite(LED13, LOW);}
    if(dato == 221){
      StatusLED13 = digitalRead(LED13);
      Serial.print(StatusLED13); // Sends 48 or 49
      }
   }
}
