hi , i have a problem plz help me, how can i read many data of arduino on processing D: ??
plz help mee :(

arduino code :

#include "DHT.h"

#define DHTPIN 7

#define DHTTYPE DHT11

DHT dht(DHTPIN, DHTTYPE);

int val = 0 ;

int val2 = 0 ;

void setup() {

Serial.begin(9600);

dht.begin();

}

void loop() {

int h = dht.readHumidity();

int t = dht.readTemperature();

val = h ;

val2 = t ;

Serial.write('h');

Serial.write(val);

Serial.write('t');

Serial.write(val2);

}

processing code :

import processing.serial.*;

Serial port;

PFont text;

int val;

void setup (){

size(500,500);

smooth();

text = loadFont("AgencyFB-Reg-48.vlw");

println(Serial.list());

port = new Serial(this,Serial.list()[1],9600);

textFont(text);

textSize(60);

}

void draw() {

background(0);

if(port.available() > 0 ){

val = port.read() ;

switch(val){

case 'h' :

val = port.read() ;

fill(#03F4FF);

text("HUMIDITY : "+ val + " %",50,300);

break;

case 't' :

val = port.read() ;

fill(#FF0303);

text("TEMPERATURE : " + val + " °C",50,125);

break;

}

}

Hi , when i´m running this example :

// Example 11-01 from "Getting Started with Processing"

// by Reas & Fry. O'Reilly / Make 2010

import processing.opengl.*;

void setup() {

size(440, 220, OPENGL);

noStroke();

fill(255, 190);

}

void draw() {

background(0);

translate(width/2, height/2, 0);

rotateX(mouseX / 200.0);

rotateY(mouseY / 100.0);

int dim = 18;

for (int i = -height/2; i < height/2; i += dim*1.2) {

for (int j = -height/2; j < height/2; j += dim*1.2) {

beginShape();

vertex(i, j, 0);

vertex(i+dim, j, 0);

vertex(i+dim, j+dim, -dim);

vertex(i, j+dim, -dim);

endShape();

}

}

}

I HAVE THE NEXT PROBLEM WHEN I´M COMPILED :
