 * @brief Haptic 4 Click example
 *
 * # Description
 * This example demonstrates the use of Haptic 4 click board by controlling
 * the attached motor vibration level.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Changes the motor vibration level every 2 seconds between MAX and MIN, 
 * and displays the currently set level on the USB UART.
