Recitation 9: Media Controller-Azena

RESITATION:

Sorry for post so late. I realized my post was missing at Sunday, while those days I could not spare time to make it up. This is my second time recitation 9, hope you can forgive my late.

Arduino:

void setup() {
Serial.begin(9600);

}

void loop() {
int sensor1 = analogRead(A0);
int sensor2 = analogRead(A1);
int sensor3 = digitalRead(9);

// keep this format
Serial.print(sensor1);
Serial.print(“,”); // put comma between sensor values
Serial.print(sensor2);
Serial.print(“,”);
Serial.print(sensor3);
Serial.println(); // add linefeed after sending the last sensor value

// too fast communication might cause some latency in Processing
// this delay resolves the issue.
delay(100);
}

Processing:

import processing.serial.*;

String myString = null;
Serial myPort;


int NUM_OF_VALUES = 3;   
int[] sensorValues;     
PImage img;
float j=0;
float i=0;
float x=0;
float y=0;
float speedX=10;
float speedY=10;


void setup() {
  size(1000, 1000);
  background(0);
  setupSerial();
  img = loadImage("pumpkin.png");
}


void draw() {
  updateSerial();
  printArray(sensorValues);

 
  imageMode(CENTER);
float j=map(sensorValues[0],0,1023,0,500);
  float i=map(sensorValues[1],0,1023,0,10);
  
    
 
  background(0);
 
  
image(img, x, y, j*1.2, j*1.2);
filter(BLUR, i);

if (sensorValues[2]==0 ){
  x=300;
  y=300;
}else{
x=x+1.5*speedX;
y=y+0.8*speedY;
if(x>width||x<0){
  speedX=-speedX;
}
if(y>height||y<0){
  speedY=-speedY;
}
}

  //
}



void setupSerial() {
  printArray(Serial.list());
   myPort = new Serial(this, Serial.list()[ 3], 9600);
  myPort.clear();
  // Throw out the first reading,
  // in case we started reading in the middle of a string from the sender.
  myString = myPort.readStringUntil( 10 );  // 10 = '\n'  Linefeed in ASCII
  myString = null;

  sensorValues = new int[NUM_OF_VALUES];
}



void updateSerial() {
  while (myPort.available() > 0) {
    myString = myPort.readStringUntil(10); 
    if (myString != null) {
      String[] serialInArray = split(trim(myString), ",");
      if (serialInArray.length == NUM_OF_VALUES) {
        for (int i=0; i<serialInArray.length; i++) {
          sensorValues[i] = int(serialInArray[i]);
        }
      }
    }
  }
}

I’d like to use two the potentiometers and a Botton to control the movements of image. At the first, I checked the code of the button online and have no idea how to move the digital Read(); to the processing, after asking help from assistant, I found out using sensorValue(); can transform all into processing;
