messenger error

Projects Programming

Hey guys i've been following this build here to make a digital color organ... Make: Projects
I've been following these instructions: Make: Projects
I am using the arduino code and the library from the links supplied in that pdf....

My arduino connects just fine, I have tried importing both the messenger library from the link in the pdf and the cmd messenger library (here: http://arduino.cc/playground/Code/CmdMessenger), but either way i'm still having the same trouble with uploading the code as it states: "messenger" does not name a type. any help is appreciated. thanks

You import libraries in Java. You include libraries in C/C++.

but either way i'm still having the same trouble with uploading the code as it states: "messenger" does not name a type.

You want help with your code, post it. Don't expect us to go looking for it. You stole it, fair and square, didn't you? That makes it yours.

here's the code

Stereo Color Organ (Receiver)
// Collin Cunningham - Makezine.com
// http://blog.makezine.com/archive/2010/11/powerleds
//
// - For controlling six LEDs via a serial connection
//
// - Listens for a six ASCII value message sent over serial,
// and parses those messages with the Arduino Messenger library:
// Arduino Playground - Messenger
// ... then uses the values to set pins 3, 5, 6, 9, 10, 11 accordingly.
//
// - Each message is composed of 6 ASCII values ranging from 0-255,
// values are seperated by a single space and the entire message
// completed with a carriage return.
// Example: 135 20 234 189 55 255 (carriage return == ASCII code 13)
//
// - Any value over 255 is redefined as a random value between 0-255
//
// - Values are inverted for use with 2 of SparkFun's ZXLD1360 LED Driver boards
// Inversion can be disabled by removing the second line of the processValue function:
// else { value = map(value,0,255,255,0); }
//

i'm still having the same trouble with uploading the code as it states: "messenger" does not name a type.

Is that the only error message you get?

i get all this ones

StereoColorOrganReceiver_r2.pde:-1: error: 'Messenger' does not name a type
StereoColorOrganReceiver_r2.cpp: In function 'void setup()':

If you've downloaded, and want to use, the CmdMessenger library, you'll need to change the #include statement and the object definition lines at least.

// CmdMessenger library available from https://github.com/dreamcat4/cmdmessenger
#include <CmdMessenger.h>

// Attach a new CmdMessenger object to the default Serial port
char field_separator = ',';
char command_separator = ';';
CmdMessenger cmdMessenger = CmdMessenger(Serial, field_separator, command_separator);

You'll need to read the documentation to see what other differences there are.
