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)
