Hello,
I am a newbie and I'm playing with processing and interfacing to my arduino. I'm trying to loop HTTP requests so that I can monitor a value on a webpage and write it out to the serial port at regular intervals. This is essentially what Tom Igoe does in the book "making things talk" but he does it with an Xport instead of with processing. I'm using the code from the example page (below) but I'd like to move the GET request into the draw loop. This seems to cause errors. I've tried adding a stop() to close the connection server at the end of the loop with no luck. Thanks for any thoughts you may have.

import processing.net.*;

Client c;
String data;

void setup() {
 size(200, 200);
 background(50);
 fill(200);
 c = new Client(this, "www.processing.org", 80); // Connect to server on port 80
 c.write("GET / HTTP/1.1\n"); // Use the HTTP "GET" command to ask for a Web page
 c.write("Host: my_domain_name.com\n\n"); // Be polite and say who we are
}

void draw() {
 if (c.available() > 0) { // If there's incoming data from the client...
   data = c.readString(); // ...then grab it and print it
   println(data);
 }
}
