How to flash app_lamp.txt

Hi everybody,

I'm doing project with arduino and I want to use app designer to flash a led and app.lamp object at the same time, transmit and receive data by USB port and trace this data from a sensor.

It's my first time I'm going to use App designer and would like to know at first how to flash app.lamp object.

If you have links to examples that can help me understand app designer do not hesitate to send them.

Thank you!

Hi Achille,

I understand that you want to change the operational state of lamp object. You can use “Enable” property to on/off the lamp. Attaching a small code for your reference.

%Call Back function of a switch component
function SwitchValueChanged(app, event) 
    value_S2 = app.Switch.Value;
    if strcmp(value_S2,'On')
        app.Lamp.Enable='on';
    else
        app.Lamp.Enable='off';
    end
end
