 * \brief BarGraph3 Click example
 * 
 * # Description
 * This application used to create various types of VU meters, 
 * status indicators, different types of counters and similar devices.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver init, enable device and set PWM
 * 
 * ## Application Task  
 * Counter passes through the loop and logs the value of the 
 * counter on the bargraph display.
