I have an arduino duemilanove, an lv-maxsonar ez1 and u have de codes in processing to make some changes in a video, the thing is that in arduino de sensor works, but arduino and processing doesn´t read de same values from the device. I will write  the code to see if someone could help me!!!!



import processing.serial.*;
import cc.arduino.*;
import processing.video.*;

Movie myMovie;

Arduino arduino;
float myValue;
float smoothValue;
float smoothness;

void setup(){
size(320, 240, P2D);
println(Arduino.list());
arduino = new Arduino(this, Arduino.list()[0], 19200);
smoothness = .4;

myMovie = new Movie(this, "examen.mov");
myMovie.loop();
}

void draw(){
myValue = arduino.analogRead(3);
println(myValue);
float dValue = (myValue-smoothValue)*smoothness;
smoothValue+=dValue;
float mapValue = map(smoothValue,40,300,255,0);
background(mapValue);
tint(255, mapValue);
image(myMovie, 0, 0, 320, 240);
}

void movieEvent(Movie myMovie) {
myMovie.read();
}

in processing only 0.0
in arduino the real values from 10 to 270,  aprox

when it works was with Standar Firmata....
