Achieve silent and reliable switching with BD8LB600FS-C and ATmega328P

/*!
 * @file main.c
 * @brief SolidSwitch3 Click example
 *
 * # Description
 * This example demonstrates the use of SolidSwitch 3 click board by controlling
 * the output state.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Enables all outputs one by one in the span of 8 seconds, and after that disables 
 * all outputs for 3 seconds. Accordingly, the outputs status will be displayed on the USB UART.
