/*!
 * @file main.c
 * @brief Button Play Click Example.
 *
 * # Description
 * This example showcases how to initialize and use the whole family of Button clicks. 
 * One library is used for every single one of them. They are simple touch detectors which 
 * send a pressed/released signal and receive a PWM output which controls the backlight on the button.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * This function initializes and configures the logger and click modules.
 *
 * ## Application Task
 * This example first increases the backlight on the button and then decreases the intensity of the backlight. When the button is touched,
 * reports the event in the console using UART communication.
