I have been working with the software. It now successfully pings an ARK server. Minecraft is not forgotten - at the moment it is a compiler directive #define MINECRAFT, if it is commented out it compiles to ARK (and maybe other steam game servers, as it is a steam ping standard)

I decided to make a extra red spot far left on the display and point the indicator there if it could not connect to server.

I also made a little bigger step from zero to 1, to make it more clear that there is no one on the server.

The enclosure is finished printing, images will come. 

Software will be uploaded when it is confirmed sort off stable...

But today it is car fixing time. Reality checks in.
