In the Processing website I found out this piece of code that requests the HTTP headers of a page and prints out the results:

I will report here the code which is shown on the Processing website at this address: HTTP CLIENT

import processing.net.*;

Client client;

void setup()
{
size(200, 200);
noStroke();
// Open a TCP socket to the host:
client = new Client(this, "processing.org", 80);

// Print the IP address of the host:
println(client.ip());

// Send the HTTP GET request:
client.write("GET /index.html HTTP/1.1n");
client.write("HOST: processing.orgnn");
}

void draw()
{
background(0);
// Print the results of the GET:
if (client.available() > 0) {
int inByte = client.read();
print((char)inByte);
} else {
println("nnThat's all, folks!n");
}
}

So we will go piece by piece and try to understand what id does

// First line imports the net library which comes
// embedded into the Processing client software.

import processing.net.*;

// Defines a default client
Client client;

void setup()
{

// Opens a window of 200 by 200 pixels
size(200, 200);

// Delete the border;
noStroke();
// Open a TCP socket to the host:
client = new Client(this, "processing.org", 80);

// Print the IP address of the host:
println(client.ip());

// Send the HTTP GET request:
client.write("GET /index.html HTTP/1.1n");
client.write("HOST: processing.orgnn");
}

void draw()
{
background(0);
// Print the results of the GET:

// Check if the website is online and Processing gets an answer
if (client.available() > 0) {
int inByte = client.read();
//writes the number of Bytes read
print((char)inByte);
} else {
println("nnThat's all, folks!n");
}
}

This may be helpful on the completion of my assignment, but still I will have to find a way to output these data into the Arduino board, and most important of all, I need to set a range of Voltage output, otherwise my game will get in fire.

Please note that the code is available at this address: Processing HTTP CLIENT .
