function Connect(~,~,~) try arduino = serial('COM4','BaudRate',115200); fopen(arduino);

        catch e
            obj = instrfind;
            fclose(obj);
            delete(obj);
            arduino = serial('COM4','BaudRate',115200);
            fopen(arduino);
        end
        set(b1,'Visible','off');
        set([b2 b3 b4],'Visible','on');
    end
    function SendData(~,~,~)
            fprintf(arduino,get(ed,'String'));
            dataReceive = fscanf(arduino);
            this is the code i found from file exchange but i want create the own  gui system
