Okay so I have successfully created a program that reads iButton ID's through a probe and displays the ID in the serial window within the Arduino software package.
My board is powered by USB and is communicating to my PC via USB too. However as I can power my board with PoE I also want to communicate the same info I can with USB via the Ethernet cable. The aim is to have just one Ethernet cable powering and communicating with the system.
If anyone knows how to communicate the same as I do with USB, I would really appreciate your help!
