Design a Media LED Widget

Introduction

The Media Led widget is a highly configurable widget that allows you to place a Led indicator on the screen in any colour and in a variety of styles.

It can be useful for indicating the status of an output and can display a symbol or text on top of the widget.

Add another Media Led and then set the properties as shown.

If the Genius environment is being used the demonstration can be tested by entering simple code in the code window.

Ensure that the Port is set to the correct port that the TIMI module is connected to.
