 * @brief H-Bridge 12 Click example
 *
 * # Description
 * This example demonstrates the use of the H-Bridge 12 click board by
 * driving the motor connected to OUT A and OUT B, in both directions with braking and freewheeling. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Driving motor in both directions for 5 seconds with a motor braking and freewheeling in between.
