Having sound as an indicator

I took out the part with the sub vi to make it simpler. I managed to make it beep when i want it to but i also have another question. How do i get the led to turn off when i press the stop button?

Here.

There are examples in the .llb files.

You forgot to save that to an earlier version of LV.  Most people can't open it.

I can't open your code, but there are a few ways to change the states of controls and indicators from multiple places.  The fancy way is to use references and property/invoke nodes.  In your simple case you can just use a local variable or control reference.

 

Right-click your LED and create a local variable.  Place it after the loop and wire a false constant from inside to loop to the local.  You may need to right-click it and change it to WRITE READ.  That way, when the loop ends the last thing that happens before the program terminates is to turn off the LED.

 

EDIT: change READ to WRITE. 🙄

I once made an XControl that's an audible indicator, and another that's an audible tweak.

Would you like them?


My answer to "do you want an XControl for ...?" these days is always a strong "NO!"  I've been burned by XControls one too many times.


So kudos for making one complete and working well enough to be willing to share 🙂

The snippet below will turn off the LED after you press the stop button.

 

I added a WAIT to your loop, you don't need it run as fast as possible.

Where has that burning come from?

XControls that you made, or XControls from others?

Both.

 

I've just had a lot of problems with them in the past... generally stemming from trying to make the control do too much.
