 * \brief Fan4 Click example
 * 
 * # Description
 * Demo application shows basic use of Fan 4 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  
 * Increases the output voltage every 500 ms until it reaches the maximum fan voltage.
 * Prints current voltase data on usbuart.
