Chat Server
A simple server that distributes any incoming messages to all
connected clients. To use telnet to your device's IP address and type.
You can see the client's input in the serial monitor as well.
Using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
But when I see the sketch comments, it seems like I just need an Arduino and an Ethernet Shield.
What do you think?How about the "Telnet" things?maybe we forgot that?
