 * @brief Proximity 18 Click example
 *
 * # Description
 * This example demonstrates the use of Proximity 18 click board by reading and 
 * displaying the proximity data on the USB UART.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger, and performs the click default configuration.
 *
 * ## Application Task
 * Reads the proximity data from 3 sensors in a multiplex mode and displays it on the USB UART 
 * approximately once per second. The higher the proximity value, the closer the detected object is.
