 * @file main.c
 * @brief MIC 3 Click Example.
 *
 * # Description
 * This is an example that demonstrates the use of the MIC 3 Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SHD to output and log module, maping GPIO for Mikrobus1, and seting SHD pin to 
 * HIGH state.
 *
 * ## Application Task
 * Turning microphone on for the 5 seconds, then turning it off for 5 seconds.
