How do I stop repeating message while moving slider?

[Alija22]

Hi. I have a problem with slider. It has a value between 20 and 60.I defined that for example if value is between 25 and 35 it should send 30 to arduino. I need to it send 30 value just one time but it sends 7 times. and my void is executed 7 times while I want to it is executed just one time. How can I fix the problem? these are blocks:

here is the serial monitor:

this is the sketch:

The slider changed event is not the place to send the new slider thumb value to Bluetooth.

Use it to change a label or button text. Send the new value from the button click.

That lets you see the new value and gives you a way to send it once when you are done.

or, you can use this extension's touchup event.

You can alternatively use a thin Canvas as a slider.

The drag and touchup events are key.

You would need to map X values into your desired range using math.

Transmit from the touch up event.

You could do something like this:
