I want to use arduino in [appdesigner].

Hello!

I want to use arduino in appdesigner, but I get an error. (as shown in the attached picture)

Error message[Too many input arguments]

Does anyone know how to solve this problem?

Reference URL

This source code communicates with arduino when [runbutton] is pressed as shown in the attached picture.(but,error)

angle=40;
first=angle/180;         %0-1の値

for j=1:20
    writePosition(s, first);
    pause(1)




    for i=40:-1:7
        val=i/180;
        writePosition(s, val);
        fprintf('Current motor position is %d degrees\n', i);
   
    end


    for i=8:3:40
        val=i/180;
        writePosition(s, val);
        fprintf('Current motor position is %d degrees\n', i);

    end

 function app = arduino

You are defining a method named arduino for your class, which is interfering with calling the arduino library function

Thank you for your response.

Which line exactly do I need to change?

(Sorry, I'm a newbie)

This didn't work.

classdef arduino < matlab.apps.AppBase

... that tells me that you tried to name your app arduino. You will need to change that name. There is no way for MATLAB to know that at one point arduino is to refer to your app but at another point arduino is to refer to the library function.

I see!

I tried to name the file [sample.mlapp].

but it didn't work...

what error do you get after you rename to sample?

Thank you!

I changed my pc and ran it and it worked!

I think perhaps it was still in the PC cache and the changes weren't taking effect!!!!
