 * \brief Mic Click example
 * 
 * # Description
 * This example showcases the initialization and configuration of the click and logger
 * modules and later on reads and displays data recorded by the mic.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes LOG communication, ADC and configures AN pin as input on MIKROBUS1.
 * 
 * ## Application Task  
 * Reads 12 bit ADC data from AN pin and displays it using the logger module.
