Protect circuits from overcurrent and overvoltage with eFuse and ATmega328

/*!
 * @file main.c
 * @brief eFuse 5 Click example
 *
 * # Description
 * This library contains API for the eFuse 5 Click driver.
 * This driver provides the functions to set the current limiting conditions 
 * to provide the threshold of the fault conditions.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, default settings turn on the device.
 *
 * ## Application Task
 * This example demonstrates the use of the eFuse 5 Click board™.
 * In this example, the app sets the current limit to 600 mA for 10 seconds 
 * and then sets the current limit to 1200 mA for the next 10 seconds
 * to protect the electrical circuit against excessive current.
 * Results are being sent to the UART Terminal, where you can track their changes.
