I'm novice at using Processing.

In my code I want to change the background to white when the capacitive sensor is held down, and then back to black when the sensor is released.

I have attempted at writing this code in both capacitive sensor code in Arduino, however when I run my code in Processing nothing is shown or changes.

Any help would be greatly appreciated.

MY ARDUINO CODE IS BELLOW

#include <CapacitiveSensor.h>

CapacitiveSensor   cs_4_2 = CapacitiveSensor(4,2);             

void setup(){

  cs_4_2.set_CS_AutocaL_Millis(0xFFFFFFFF);     
  Serial.begin(9600);
}

void loop(){

  long start = millis();
  long total1 =  cs_4_2.capacitiveSensor(30);

  Serial.println(total1); 
  Serial.print(",");                

  delay(10);                              
}

MY PROCESSING CODE IS BELLOW

import processing.serial.*;

int touch1Value = 0;

int threshold = 30;

Serial myPort;

void setup(){

  size (500,500);

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

  myPort.bufferUntil('\n');
}

void draw(){

  background (0);

  println("touch1Value:"+touch1Value);

  if (touch1Value == 1){

    background (255,255,255);
  }
}

void serialEvent(Serial myPort){

  String inString = myPort.readStringUntil('\n');

  if (inString != null){

    inString = trim (inString);

    float[] touches = float (split(inString, ","));

    if (touches.length >=1){

      touch1Value = touches[0] >= threshold ? 1: 0;
    }
  }
}

How can I make these circles move as individual functions? I tried using different variables for each circle, and still no good!

----------main program (dont trust in what is inside, it have been the result os my attempts)-------------------------

float x;
float y;
Trail trail = new Trail();
Trails trails = new Trails();
PVector startPoint;



void setup() {

  size(500, 500);

  for (int i = 0; i < trail.trailSize; i++) {  
     trails.Trails();
  }
}

void draw() {
  background(255);
  ellipse(x, y, 50, 50);



  if (mousePressed) {

    for (int i = 0; i < trails.maxTrails; i++) {
      trails.drawTrails();
    }
    x = mouseX;
    y = mouseY;
  }
}

------------------first class-----------------------------------------

class Trail {
  final int DEAD = 0;
  final int ALIVE = 1;
  final int ZOMBIE = 2;

  ArrayList<PVector> aTrail;
  color trailColor;
  int state;
  int tnumber;

  int trailSize = 1000;
  int totalTrails = 0;

  Trail() {
    aTrail = new ArrayList<PVector>(trailSize);
    trailColor = #6F480D;
    state = DEAD;
    tnumber = totalTrails + 1;
    totalTrails++;
  }

  int getTrailNumber() {
    return tnumber;
  }

  void addPointTrail(PVector p) {
    if (aTrail.size() > trailSize)
      aTrail.remove(0);
    aTrail.add(p);
  }

  void setColorTrail(color c) {
    trailColor = c;
  }

  void drawTrail() {
    float shade;

    if (aTrail.size() > 1) {
      shade = 256.0 / aTrail.size();
      for (int i=0; i < aTrail.size ()-1; i++) {
        strokeWeight(10);
        stroke(trailColor, shade*(i+1) );
        line(aTrail.get(i).x, aTrail.get(i).y, aTrail.get(i+1).x, aTrail.get(i+1).y);
      }
    }
  }

  void reduceTrail() {
    aTrail.remove(0);
    if (aTrail.size() == 0) setDeadTrail();
  }

  void setAliveTrail() {
    state = ALIVE;
  }

  void setDeadTrail() {
    state = DEAD;
  }

  void setZombieTrail() {
    state = ZOMBIE;
  }

  boolean isZombie() {
    return state == ZOMBIE;
  }

  boolean isDead() {
    return state == DEAD;
  }
}

---------- and the other class given is -------------------------------

class Trails {
  int maxTrails = 1000;
  ArrayList<Trail> aTrails;

  Trails() {
    aTrails = new ArrayList<Trail>(maxTrails);
  }

  int newTrail(PVector startPoint, color c) {
    Trail t = new Trail();

    aTrails.add(t);
    t.setColorTrail(c);
    t.addPointTrail(startPoint);
    t.setAliveTrail();
    return t.getTrailNumber();
  }

  void drawTrails() {
    Trail t;
    for (int i = 0; i < aTrails.size (); i++) {
      t = aTrails.get(i);
      t.drawTrail();
      if (t.isZombie()) t.reduceTrail();
      if (t.isDead()) aTrails.remove(i);
    }
  }

  void setZombieTrail(int tn) {
    Trail t;
    int i = 0;
    boolean found = false;

    t = aTrails.get(0);
    while ( i < aTrails.size() || !found) {
      t = aTrails.get(i);
      found = (t.getTrailNumber() == tn);
      i++;
    }

    t.setZombieTrail();
  }
}

I sort of understand what I'm doing wrong, but I don't know how to fix it. What should I do?

I found some codes online to use the arduino uno and processing to transfer one image through the Arduino serial port (TX and RX). I need to transfer 6 images. How can i modify the processing code or arduino code to be able to transfer all images one after the other. Example: transfer image 1, then 2 etc.

Below is the Arduinocode:

     #include <SD.h>   

     File photoFile;   



     void setup(){   

      Serial.begin(115200);   



      //Serial.println("initializing sd card");   
      pinMode(10,OUTPUT);     // CS pin of SD Card Shield   

      if (!SD.begin(10)) {   
       Serial.print("sd initialzation failed");   
       return;   
      }   

     }   


     void loop(){   

      while(1){   

       Serial.flush();     




         File photoFile = SD.open("IMAGE09.jpg");   

         if (photoFile) {   
          while (photoFile.position() < photoFile.size()) {   


           Serial.write(photoFile.read());   
          }   

          photoFile.close();   

         }    

         else {   
          Serial.println("error sending photo");   
         }         
        }   

       }   
      }   

PROCESSING CODE: // READ: Upload arduino code then processing.File //will be created in processiong library under my documets // //image will begin to transfer. . Click on //the grey processing box AFTER complete imgae size // has been reached... and press any button. //Image should have transferred.Click stop.

import processing.serial.*;  

Serial myPort;

OutputStream output;  
//OutputStream output2;

void setup() 
{  

  size(320, 240);  

  //println( Serial.list() );  
  myPort = new Serial( this, Serial.list()[0], 115200);  
  myPort.clear();  
  output = createOutput("IMAGE09.jpg");

}  


void draw() 
{  

  try {   
    while ( myPort.available () > 0 ) 
    {  
      output.write(myPort.read());
    }
  }   
  catch (IOException e) {  
    e.printStackTrace();
  }
}  


void keyPressed()
{  
  try 
  {   
    output.flush(); // Writes the remaining data to the file 
    output.close();  // Finishes the file 
  }   

  catch (IOException e)
  {  
    e.printStackTrace();
  }
}    

// ============================================================
// this function catches a serial event when the Arduino board responds

void serialEvent(Serial p) { 
  // get the ASCII string:
 // String inString = myPort.readStringUntil('\n');  
  String inString = p.readStringUntil('\n');

  if (inString != null) {
    // trim off any whitespace:
    inString = trim(inString);
    int[] rawValues = int(split(inString, ","));
    for(int i=0; i<numOfSensors; i++){

      //sensorValues[i] = map(rawValues[i], 0, 100, 0, 1);

Does someone know how to create a runnable .jar or .exe file, that opens a window and not something in fullscreen?

in my code , obsX is the x position, obsY is y position:

obsX=int(random(-50, width-200));

obsY=height-100;

obsX2=int(random(-50, width-200));

obsY2=height+200;

obsX3=int(random(-50, width-200));

obsY3=height+400;

obsWidth=200;

obsHeight=100;

obsSpeed=5;

and i write a function call wood to make it move those objects upward:

void wood() {

image(cloud,obsX, obsY, obsWidth, obsHeight); obsY=obsY-obsSpeed;

image(cloud,obsX2, obsY2, obsWidth, obsHeight); obsY2=obsY2-obsSpeed;

image(cloud,obsX3, obsY3, obsWidth, obsHeight); obsY3=obsY3-obsSpeed;

}

How could i use array and for loop to simplify the code??

can someone help?
