Explore the endless potential of proximity detection with TMD3719 and ATmega328P

 * @file main.c
 * @brief Proximity12 Click example
 *
 * # Description
 * This function demonstrates the use of Proximity 12 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads the proximity and ALS values and displays the results on the USB UART 
 * approximately every 100ms.
