Arduino Code for push button to be controlled by LabView

Hello everybody,
I am trying to make an interface for Arduino with Labview.
the idea is simple!!!
I want to push a button in LabVIEW and the LED turns on, on the Arduino.
I could not find a similar code on the internet.
does anyone have any Arduino code that can interpret the Labview command? or can anyone give me hint how to do it?

So tell us what labview sends when you press the button.

I suggest that you read the Serial Input Basics thread to get some ideas.

You can test what you implement using the serial monitor. Once that works, you can implement the complement in labview.
