Hi all,
When setting up a connection with the Arduino board the following errors occur:
Error using matlab.hwmgr.internal.hwsetup.appdesigner/DropDown/setValue
Too many input arguments.
Error in matlab.hwmgr.internal.hwsetup.appdesigner.DropDown/dropdownCallbackHandler (line 49)
obj.setValue(obj.Items{obj.ValueIndex});
Error in matlab.hwmgr.internal.hwsetup.appdesigner.DropDown>@(varargin)obj.dropdownCallbackHandler(varargin{:}) (line 45)
obj.Peer.ValueChangedFcn = @obj.dropdownCallbackHandler;
Error using matlab.ui.control.internal.controller.ComponentController/executeUserCallback (line 453)
Error while evaluating DropDown PrivateValueChangedFcn.
I know for sure the board is connected well to the PC I'm using...
Can someone help me out?

No, I could not solve the problem. Therefore, I did not use Matlab for the project.

Hi Patrick,
You can use the "arduino()" command to resolve the error:
a = arduino('<port>','Nano33IoT','Libraries','<library_name>')
For more details on 'arduino' function, please refer to the following documentation:
