I am new to doing this stuff.  I finally figured out you need to have a separate program to "process" the code.  I have been trying to do some projects that are in the Arduino cookbook 2nd Edition.  I have done simple light projects and the board appears to be good.  I purchased an adapter for the Wii Nunchuck.  The Arduino program did seem to work but I decided to try the processing code shown on page 130-131. I built the code and had checked it but It doesn't seem to want to Process it.

It stop at: #include <Wire.h>

then there is: #include "nunchuck.h"

It talks about the Nunchuck library on recipe 16.5.  What program do I use to build it with?

This is far more complex than I wanted it to be. 

Looking on the internet I saw it was talking about a library.  I have no clue how to build one or get one.  What would I use to even build one. I don't get it!

I would any help I can get!

Here is the code:

/*
* WiichuckSerial
* Uses Nunchuck Library discussed in recipe 16.5
* sends comma-seperated values for data
* Label string separated by commas can be used by receiving program
* to identify fields
*/


#include <Wire.h>
#include "Nunchuck.h"

// values to add to the sensor to get zero reading when centered
int offsetX, offsetY, offsetZ;

#include <Wire.h>
#include "Nunchuck.h"
void setup()
{
  Serial.begin(57600);
  nunchuckSetPowerpins()
  nunchuckInit(); // send the intitialization handshake
  nunchuckRead; // ignore the first time
  delay(50);
}
void loop()
{
  nunchuckRead();
  dalay(6);
  nunchuck_get_data();
  boolean btnC = nunchuckGetValue(wii_btnC);
  boolean btnC = nunchuckGetValue(wii_btnZ);
 
  if(btnC) {
    offsetX = 127 nunchuckGetValue(wii_accelX);
    offsetX = 127 nunchuckGetValue(wii_accelY);
  }
  serial.print("Data,");
  printAccel(nunchuckGetValue(wii_accelX),offsetX;
  printAccel(nunchuckGetValue(wii_accelY),offsetY;
  printButton(nunchuckGetValue(wii_btnZ));
 
  Serial.println();
}

void printAccel(int value,int offset)
{
  serial.print(adjReading(value, 127-50, 127+50, offset));
}

void printJoy(int value)
{
  Serial.print(adjReading(value,0, 255, 0));
  Serial.print(",")
}

void printButton(int value)
{
  if( value != 0)
     value = 127;
  Serial.print(value,DEC);
  Serial.print(",");
}

int addReading( int value, int min, int max, int offset)
{
  value = constrain(value + offset, min, max);
  value = map(value, min, max, -127, 127);
  return value;
}
