 * \brief StereoAmp Click example
 * 
 * # Description
 * This is an example which demonstrates the use of StereoAmp Click board -
 * stereo amplifier and is ideal for battery operated devices or as a lab amplifier.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Application Init performs Logger and Click initialization.
 * 
 * ## Application Task  
 * This examples first set volume level 20 of 31 ( gain: 1,5 dB ) for 10 seconds. 
 * After that, we increase the volume to level 10 ( gain: -13,5 dB ) for the next 10 seconds. 
 * Results are being sent to the UART Terminal where you can track their changes.
