Accurately monitor vibrations with LDT0-028K and MK64FN1M0VDC12 for enhanced safety

/*!
 * @file main.c
 * @brief VibraSense2 Click example
 *
 * # Description
 * This example shows capabilities of Vibra Sense 2 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initalizes I2C driver and makes an initial log.
 *
 * ## Application Task
 * Demonstrates use of Vibra Sense 2 Click board by checking
 * vibration levels and displaying changes via USART terminal.
