 * \brief Fan Click Example
 *
 * # Description
 * This application is controller for powering and regulating of fan.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of click driver and usb uart serial terminal for results
 * logging.
 *
 * ## Application Task
 * Performs a control of the fan and reads rotation per minute (RPM).
 * Results will be sent to the usb uart terminal.
