- Telnet client
-
- This sketch connects to a a telnet server (http://www.google.com)
- using an Arduino Wiznet Ethernet shield. You'll need a telnet server
- to test this with.
- Processing's ChatServer example (part of the network library) works well,
- running on port 10002. It can be found as part of the examples
- in the Processing application, available at
- http://processing.org/
-
- Circuit:
- * Ethernet shield attached to pins 10, 11, 12, 13
