Is it possible to incorporate the CMU cam made to use with the Boe Bot Basic Stamp on the Arduino?  And if so, does anyone have a sample sketch?  I'm doing a project for a class, and I checked out a CMU cam but all the instructions that came with it are for the Basic Stamp language, and I have no clue where to begin.  Just so you know how I want to use it, I want the CMU cam to be able to distinguish a golf ball from its surroundings.  Or in other words, see white against green grass or a dark floor.  Please help.

It looks like the protocol is 9600 baud ascii over TTL Serial so you should be able to use it from an Arduino.

Read the manual: http://www.parallax.com/Portals/0/Downloads/docs/prod/robo/CMUcam%20Manual.PDF

I don't know if it can track something small and white like a golfball.

I have the manual, and it makes no sense to me.  I do not understand the Basic Stamp language, I barely understand the arduino language.  When I say I have no clue where to begin, I mean no clue what so ever.  A sample sketch from someone that has used it incorporated with the arduino would be great, and a wiring diagram or even and actual picture of one wired up would be awesome.  If I mess the camera up from bad wiring, I have to replace it, so I'd rather not do that.  Thanks.

The interface is fairly straightforward.  You send a short command line and get a line or series of lines in reply.  The lines end in a Return ('\r') character.

Again, no clue what you're talking about. I've never seen that return symbol your talking about. You sure thats with the arduino? I have not the newest arduino, but the one right before it. It uses a style of c++.

Here's a sample of my code, so you know what I'm looking at.  It measures distance with a PING))) sensor and then writes it to an LCD screen:

Code:

void setup(){
  Serial.begin(9600);
  Serial.print(12, BYTE);
  Serial.print(128, BYTE);
  Serial.print("Distance="); 
}
void loop(){
  int tone_freq=0;
  long duration, inches;
  pinMode(3, OUTPUT);
  digitalWrite(3, LOW);
  delayMicroseconds(2);
  digitalWrite(3, HIGH);
  delayMicroseconds(5);
  digitalWrite(3, LOW);
  pinMode(3, INPUT);
  duration = pulseIn(3, HIGH);
  Serial.print(148, BYTE);
  Serial.print(duration);
  inches = (duration/2)/74;
  Serial.print(137, BYTE);
  Serial.print(inches);
  delay(100);
  tone_freq= inches*100;
  tone(2,tone_freq);
}

Now it's our turn to not have a clue what you're talking about - what has Ping got to do with CMUcam?

\r is a standard C representation of carriage-return.

Nothing, that's just an example of the language I'm using in case it's different from previous Arduinos.

I barely understand the arduino language

If you go to file/examples in the IDE, you'll find lots of ways of learning.
