 * @brief Ambient 23 Click example
 *
 * # Description
 * This example demonstrates the use of Ambient 23 click board by measuring 
 * the ambient light level in Lux.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver, checks communication by reading part ID
 * and performs the click default configuration.
 *
 * ## Application Task
 * Measuring ambient light level by reading data from the Ambient 23 click board
 * and displaying it using UART Serial terminal.
