Datenübertragung Arduino Mega zu Labview

Labview erkennt nur den Eingag wenn ich dann auch schreibe

Serial.print(Eingang 13);

z.B Beispiel wenn ich z.B die Übung Blink nehme,
müsste man doch dann in Labview die 1 dann sehen oder?
Danke für euer HIlfe

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.

This example code is in the public domain.

// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
Serial.begin(9600);
pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
Serial.print(led);
}
