how to use sensor(arduino) to control some images in Processing

ophelie

Hi all, I am curently working for one installation with Arduino and Processing. In general, there will be 4 sensors to detecting the movement of ppl in this project. These sensors will be located in the 4 corners of one image. Once one sensor detect someone's movement, we will immediately see that one image transforme into another one. The others sensors work in the same way. And the image will be changed all the time once one sensor catch one movement.

The main problem for me is writing the programe with Processing. (I hope that the animation like some circles turn to a pack of molecule.) But the transformation must be happened when the sensor catch something. I guess that the problem probably is the communication between Arduino and processing.

I am totally a beginner of the language java. I have already tried to find some online tutorials, but i can't find any one because the most of transformations happened with our mouse.

So i am here for looking for help. Anyone knows how to transform one image into another accroding to the movement of ppl specially with arduino? Or anyone can give me some advices ou idee?

Thanks a lot !!!

PS : i use infrared proximity sensor (Sharp GP2Y0A02YK0F)G

Now, I have to say it is not clear what you want to do. Here:

These sensors will be located in the 4 corners of one image

Do you mean that the sensors are located in four different corners in a room and they will affect each corner in your sketch? Can you clarify this as it is a very important detail.

I guess that the problem probably is the communication between Arduino and processing.

I will strongly suggest to work on a simple demo where you work with your ardunio and one sensor + processing. The concept here is for you to become comfortable working with processing, to make sure your arduino+processing communication is working and that you understand your sensor. This program is also very important so you can test any of your sensors to make sure each of them works and that they all behave similarly as dictated by specs. For example, if you are either 20 or 50 cm in front of the sensor, do all sensors output the same value?

What code do you have so far?

Thanks so much for your information !!!

This is one part of my code Arduino

   #include <SharpIR.h>

  // declarations les variables 

    int analogPin1 = A0;   // choose the input pin for IR sensor    
    int relayPin1 = 8;     // inputPin for Relay   

    int val = 0;           // variable for reading the pin status

    int pirState1 = LOW;    // we start, assuming no motion detected
    int code_capteur1 = 1;   // code of IR sensor for communicating with Processing

  void setup() {
    Serial.begin(9600);
    pinMode(relayPin1, OUTPUT);
    digitalWrite(relayPin1, LOW);

  }

  void loop() {                   //declaration des variables liees aus IR sensors
    gestion_IR_sensor(analogPin1, pirState1, relayPin1, code_capteur1);
  }

  void gestion_IR_sensor ( int analogPin, int etat_capteur, int numero_pin_relay, int code_capteur) {               //int numero_pin_capteur, 
    int valeur; 
    int valeuri = analogRead(analogPin);     // read input value
    if (valeuri > 150) {
      valeur = 1;
    }
    else{
      valeur = 0;
    }

    Serial.print(code_capteur);             //send code state of IR sensor
    Serial.println(valeur);               

    if (valeur == HIGH) {                    //check if the input is HIGH
      digitalWrite(numero_pin_relay, HIGH);  // turn relay On
      delay(2500);                              // delay 2500milleseconds
      if (etat_capteur == LOW) {
        etat_capteur == HIGH;
      }
    } else {
      digitalWrite(numero_pin_relay, LOW);    // turn relay OFF
      delay(300);
      if (etat_capteur == HIGH){
        etat_capteur == LOW;
        }  
    }
  }
