Control App designer lamp from Matlab script

Hi, everyone.

I have designed an app with a start button and a lamp called NSg. when I click the start button, its callback function will call this code in my Matlab Script:

      function  disableLamp()
          app.NSgLamp.Enable = 'off';
          disp("works");
      end

however, this (app.NSgLamp.Enable = 'off') seems does not work for me, can anyone tell me how to do this. Thanks a lot.

Hi Alex.

1. Firstly, make sure that NSgLamp object is correctly defined in App designer or not.
2. Check if the callback for when the start button is defined correctly and also see if disableLamp() function is called in it.
3. If the line "app.NSgLamp.Enable = 'off'" still doesn't work, then you can try replacing it with the following line of code:

set(app.NSgLamp, 'Enable', 'off');

This is the complete code for the updated function:

function disableLamp(app)
    set(app.NSgLamp, 'Enable', 'off');
    disp("works");
end

If you have already tried these steps and are still having issues, please provide more information about the error message you are receiving or the behavior you are observing.
