You're most welcome.

Apparently, it isn't bluetooth. As it works on iPhones, it can't be NFC.

I don't have any UdpBytewise files on my machine, and the sketch compiles ok without them.

DuaneB has some excellent tutorials on the subject. Start with http://rcarduino.blogspot.co.uk/2012/01/how-to-read-rc-receiver-with.html.

I'm sure you get more information than just 'Error compiling".

Here is the sketch, directly from the zip file. I didn't have to download any additional libraries.

Code:

#include <SPI.h>
#include <Ethernet.h>
#include <Utility\Socket.h>

// Make up a mac Address & an IP address. Both should be globally unique or
// at least unique on the local network.
static byte g_abyMyMacAddress[] = {0x00,0x1A,0x4B,0x38,0x0C,0x5C};
static IPAddress g_MyIPAddress(192,168,15,44);

// The machine to wake up. WOL should already be configured for the target machine.
// The free windows program "Wake On LAN Ex 2" by Joseph Cox can be useful for testing the remote
// machine is properly configured. Download it here: http://software.bootblock.co.uk/?id=wakeonlanex2
static byte g_TargetMacAddress[] = {0x00,0x1A,0x4D,0x59,0x98,0xbc};

void setup ()
{
  Ethernet.begin(g_abyMyMacAddress, g_MyIPAddress);
 
  Serial.begin(9600);
  Serial.println("Wake on Lan (WOL) Demo");
  Serial.println("Send 'w' to initiate WOL");
}
 
void loop()
{
 
  // When 'w' is received, send a magic packet to wake the remote machine.
  if(Serial.available() > 0)
    if(Serial.read() == 'w')
    {
      SendWOLMagicPacket(g_TargetMacAddress);
      Serial.println("Magic packet sent");
    }
}

void SendWOLMagicPacket(byte * pMacAddress)
{
  // The magic packet data sent to wake the remote machine. Target machine's
  // MAC address will be composited in here.
  const int nMagicPacketLength = 102;
  byte abyMagicPacket[nMagicPacketLength] = { 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF };
  byte abyTargetIPAddress[] = { 255, 255, 255, 255 }; // don't seem to need a real ip address.
  const int nWOLPort = 7;
  const int nLocalPort = 8888; // to "listen" on (only needed to initialize udp)

 
  // Compose magic packet to wake remote machine.
  for (int ix=6; ix<102; ix++)
    abyMagicPacket[ix]=pMacAddress[ix%6];
 
  if (UDP_RawSendto(abyMagicPacket, nMagicPacketLength, nLocalPort,
  abyTargetIPAddress, nWOLPort) != nMagicPacketLength)
    Serial.println("Error sending WOL packet");
}

int UDP_RawSendto(byte* pDataPacket, int nPacketLength, int nLocalPort, byte* pRemoteIP, int nRemotePort)
{
  int nResult;
  int nSocketId; // Socket ID for Wiz5100

  // Find a free socket id.
  nSocketId = MAX_SOCK_NUM;
  for (int i = 0; i < MAX_SOCK_NUM; i++)
  {
    uint8_t s = W5100.readSnSR(i);
    if (s == SnSR::CLOSED || s == SnSR::FIN_WAIT)
  {
      nSocketId = i;
      break;
    }
  }

  if (nSocketId == MAX_SOCK_NUM)
    return 0; // couldn't find one.

  if (socket(nSocketId, SnMR::UDP, nLocalPort, 0))
  {
    nResult = sendto(nSocketId,(unsigned char*)pDataPacket,nPacketLength,(unsigned char*)pRemoteIP,nRemotePort);
    close(nSocketId);
  } else
    nResult = 0;

  return nResult;
}

I clicked on the link at the end of "Here's the source for...", to download the sketch. Unzipped it and opened it in the IDE. The link points to http://www.blueleafsoftware.com/Products/MegunoLink/Downloads/WOLTest.zip.

Colour coding in the IDE is really rather hit and miss. It relies on library developers providing the appropriate information, in the form of a keywords.txt file, in the library directory.

They are all connected. It doesn't matter which you use.

Does it compile? What happens when you run it?

You might need to add

Code:

#include <Wire.h>

at the top.

The download on the first link compiled ok in IDE 1.0.1.

This is an Arduino forum, not Processing. Try asking at http://forum.processing.org/programming-questions.

I can't come up with the code..

Which code? The Arduino side is trivial, analogRead(), then Serial.write() or Serial.print(). Ask at Processing's forum for that side.

It isn't interrupt driven. It is called after each iteration of loop(), in main.cpp, which the Arduino IDE adds to your sketch:

Code:

#include <Arduino.h>

int main(void)
{
init();

#if defined(USBCON)
USBDevice.attach();
#endif

setup();
   
for (;;) {
loop();
if (serialEventRun) serialEventRun();
}
       
return 0;
}

Are you asking for help with the Processing code? Processing has its own forum at http://forum.processing.org/.

All the Arduino code will be doing is sending the result of the analogRead(), over serial, to Processing.

PS3 controllers are bluetooth devices, so you'll need a bluetooth module/shield. Circuits@Home have a USB host shield that supports usb bluetooth dongles, and they have a PS3 controller library for it.
