 * @file main.c
 * @brief VibroMotor4 Click example
 *
 * # Description
 * This library contains API for Vibro Motor 4 Click driver.
 * The library initializes and defines the I2C bus drivers
 * to write and read data from registers and PWM module.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C and PWM module, log UART, and additional pins.
 * After successful driver init, executes a default configuration
 * and configures Vibro Motor 4 Click board™.
 *
 * ## Application Task
 * This is an example that shows the use of a Vibro Motor 4 Click board™.
 * Changing duty cycle results in different vibrations.
 * Results are being sent to the Usart Terminal where you can track their changes.
