Achieve versatile motion detection for diverse needs with EKMC1603111 and ATmega2560

/*!
 * @file main.c
 * @brief Motion 4 Click Example.
 * 
 * # Description
 * This example demonstrates the use of Motion 4 Click boards.
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables the motion sensor.
 *
 * ## Application Task
 * It checks if the sensor has detected movement and therefore displays 
 * the desired message on the USB UART.
