 *
 * # Description
 * Demo application shows basic usage of Buck 9 click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring clicks and log objects.
 * Settings the click in the default configuration.
 * 
 * ## Application Task  
 * Enable and Disable device every 5 seconds.
