 * 
 * # Description
 * This demo-app shows the ADC values using POT 2 click board.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configures clicks and log objects.
 * 
 * ## Application Task  
 * Demo app reads ADC data and displays them as dec and hex values every second
