Arduino and Processing (PDE) via Ethernet

Question

Arduino: Is it possible to communicate with Arduino through Ethernet, using a Processing (PDE) script?

I've already created a desktop application using Processing, but in this case I communicate with Arduino through the USB.

Answer 1

Yes you can You could for example create an arduino chat server : http://arduino.cc/en/Tutorial/ChatServer And create a processing client like this : http://processing.org/reference/libraries/net/Client_write_.html

ofcourse you would need to change the
myClient = new Client(this, "127.0.0.1", 10002);
to

myClient = new Client(this, "IP of Arduino", 23);

If you would then connect with a telnet session to the arduin o you would see output from the prosessing script comming back from the arduino
