 * \brief Pot3 Click example
 * 
 * # Description
 * This application reads voltage value, calculates it to millivolts and then 
 * logs it to the uart terminal.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes devices module.
 * 
 * ## Application Task  
 * Reads VOUT value calculated to millivolts with 2000 conversions
 * included in one measurement cycle.
