 * @file 
 * @brief LedDriver4 Click example
 * 
 * # Description
 * This click has the ability to dim the connected LED array, without producing any noise on the output.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the GPIO driver and
 * configures the PWM peripheral for controlling the LED array intensity.
 * 
 * ## Application Task  
 * Increases and decreases LED array intensity
 * ( first increases light intensity to the maximum and then decreases to the minimum ).
 * Results are being sent to the Usart Terminal where you can track their changes.
