 * \brief DcMotor2 Click example
 * 
 * # Description
 * This library contains API for the DC Motor 2 Click driver.
 * This example showcases how to initialize and use the DC Motor 2 Click. The Click contains a 
 * Driver IC for DC motors which can spin the motor clockwise, counter-clockwise, break it and
 * completely stop the motor. The example needs a DC motor and a power supply in order to work.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * This function initializes and configures the logger and Click modules.
 * 
 * ## Application Task  
 * This is an example that demonstrates the use of the DC Motor 2 Click board.
 * DC Motor 2 Click communicates with register via PWM interface.
 * It shows moving in the Clockwise direction from slow to fast speed
 * and from fast to slow speed, then rotating Counter Clockwise,
 * Results are being sent to the Usart Terminal where you can track their changes.
