/*
* This usermod performs a ping request to the local IP address every 60 seconds.
* By this procedure the net services of WLED remains accessible in some problematic WLAN environments.
*
* Usermods allow you to add own functionality to WLED more easily
* See: https://github.com/Aircoookie/WLED/wiki/Add-own-functionality
*
* v2 usermods are class inheritance based and can (but don't have to) implement more functions, each of them is shown in this example.
* Multiple v2 usermods can be added to one compilation easily.
*
* Creating a usermod:
* This file serves as an example. If you want to create a usermod, it is recommended to use usermod_v2_empty.h from the usermods folder as a template.
* Please remember to rename the class and file to a descriptive name.
* You may also use multiple .h and .cpp files.
*
* Using a usermod:
* 1. Copy the usermod into the sketch folder (same folder as wled00.ino)
* 2. Register the usermod by adding #include "usermod_filename.h" in the top and registerUsermod(new MyUsermodClass()) in the bottom of usermods_list.cpp
