Make your own customizable hmi in the app without the need of a computer, you can select from seven different objects (widgets): button, switch, led, display 7 segments, numeric display, bar indicator, gauge and slider.
In this Lite version, the app is free but with not all the features from the full version, you can only use four of the seven widgets: switch, led, bar indicator and display 7 segments.
