Arduino and TouchOsc

Projects Programming

Hi, i've just bought my Arduino UNO shield and now i'm trying to turn on a led with TouchOSC, throw Processing.
I tested the code with an LED and it worked, but when I tried to adapt the code for 3 LEDs only the first led worked.
Here i post you the code:
Arduino:

int testo=0;
void setup()
{
  Serial.begin(9600);
  pinMode(13,OUTPUT);
  pinMode(12,OUTPUT);
  pinMode(11,OUTPUT);
}

void loop()
{
  if(Serial.available()>0)
  {
    testo=Serial.read();
    if(testo=='R')
      digitalWrite(13,HIGH);
    if(testo=='r')  
      digitalWrite(13,LOW);
    if(testo=='Y')
      digitalWrite(12,HIGH);
    if(testo=='y')  
      digitalWrite(12,LOW);
    if(testo=='G')
      digitalWrite(11,HIGH);
    if(testo=='g')  
      digitalWrite(11,LOW);
  }
}

Processing:

import oscP5.*;
import netP5.*;
import processing.serial.*;

Serial arduinoPort;
OscP5 oscP5;

int led=0;
int [] Rled=new int[2];
int [] Yled=new int[2];
int [] Gled=new int[2];

void setup()
{
  size(100,100);
  noStroke();
  oscP5 = new OscP5(this,8000);
  arduinoPort=new Serial(this,Serial.list()[0], 9600);
}

void oscEvent(OscMessage theOscMessage)
{
  String addr=theOscMessage.addrPattern();
  if(addr.indexOf("/1/toggle1")!=-1)
  {
    int i=int((addr.charAt(9)))-0x30;
    Rled[i]=int(theOscMessage.get(0).floatValue()); 
  }
  if(addr.indexOf("/1/toggle2")!=-1)
  {
    int i=int((addr.charAt(9)))-0x30;
    Yled[i]=int(theOscMessage.get(1).floatValue()); 
  }
  if(addr.indexOf("/1/toggle3")!=-1)
  {
    int i=int((addr.charAt(9)))-0x30;
    Gled[i]=int(theOscMessage.get(0).floatValue()); 
  }
}

void draw()
{
  background(50);
  if(Rled[1]==0)
  {
    arduinoPort.write("r");
    led=0;
  }
  if(Rled[1]==1)
  {
    arduinoPort.write("R");
    led=255;
  }
  if(Yled[1]==0)
  {
    arduinoPort.write("y");
    led=0;
  }
  if(Yled[1]==1)
  {
    arduinoPort.write("Y");
    led=255;
  }
  if(Gled[1]==0)
  {
    arduinoPort.write("g");
    led=0;
  }
  if(Gled[1]==1)
  {
    arduinoPort.write("G");
    led=255;
  }
  fill(led,0,0);
  ellipse(50,50,50,50);
}

Can anyone help me?
PS:Sorry for my bad english :wink:

Ok, i resolved the problem myself.
I post the complete and correct code.
Arduino:

int testo=0;
void setup()
{
  Serial.begin(9600);
  pinMode(13,OUTPUT);
  pinMode(12,OUTPUT);
  pinMode(11,OUTPUT);
}

void loop()
{
  if(Serial.available()>0)
  {
    testo=Serial.read();
    if(testo=='R')
      digitalWrite(13,HIGH);
    if(testo=='r')  
      digitalWrite(13,LOW);
    if(testo=='Y')
      digitalWrite(12,HIGH);
    if(testo=='y')  
      digitalWrite(12,LOW);
    if(testo=='G')
      digitalWrite(11,HIGH);
    if(testo=='g')  
      digitalWrite(11,LOW);
  }
}

Processing:

import oscP5.*;
import netP5.*;
import processing.serial.*;

Serial arduinoPort;
OscP5 oscP5;

int led=0;
int Rled=0;
int Gled=0;
int Yled=0;


void setup()
{
size(300,100);
  noStroke();
  oscP5 = new OscP5(this,8000);
  arduinoPort=new Serial(this,Serial.list()[0], 9600);
}

void oscEvent(OscMessage theOscMessage)
{
  String addr=theOscMessage.addrPattern();
  if(addr.indexOf("/1/toggle1")!=-1)
  {
    int i=int((addr.charAt(9)))-0x30;
    Rled=int(theOscMessage.get(0).floatValue()); 
  }
  if(addr.indexOf("/1/toggle2")!=-1)
  {
    int i=int((addr.charAt(9)))-0x30;
    Yled=int(theOscMessage.get(0).floatValue()); 
  }
  if(addr.indexOf("/1/toggle3")!=-1)
  {
    int i=int((addr.charAt(9)))-0x30;
    Gled=int(theOscMessage.get(0).floatValue()); 
  }
}

void draw()
{
  background(50);  
  if(Rled==0)
  {
    arduinoPort.write("r");
    led=0;
  }
  if(Rled==1)
  {
    arduinoPort.write("R");
    led=255;
  }
  fill(led,0,0);
  ellipse(50, 50, 50, 50);
  if(Yled==0)
  {
    arduinoPort.write("y");
    led=0;
  }
  if(Yled==1)
  {
    arduinoPort.write("Y");
    led=255;
  }
  fill(led,0,0);
  ellipse(150, 50, 50, 50);
  if(Gled==0)
  {
    arduinoPort.write("g");
    led=0;
  }
  if(Gled==1)
  {
    arduinoPort.write("G");
    led=255;
  }
 fill(led,0,0);
  ellipse(250, 50, 50, 50);
}

I used 13,12 and 11 pins
I hope this will be helpful to someone!

Thanks it helped me newbie doing more or less the same thing as you did
