 * \brief Pot Click example
 * 
 * # Description
 * Click board with the accurate selectable reference voltage output.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Performs logger and Click initialization.
 * 
 * ## Application Task  
 * Reads and displays on the USB UART the voltage level measured from AN pin.
