 * @brief VibroMotor3 Click example
 *
 * # Description
 * This example shows the capabilities of the Vibro Motor 3 click board 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initalizes I2C driver, PWM driver and configures Vibro Motor 3 click board.
 *
 * ## Application Task
 * Changing duty cycle applied in order to get different vibrations.
