Processing (Pyroelectric PIR Part3)

I have decided to post the Processing code to render the data from the Arduino. This my first processing project. I have kept the code very simple and with that flexible. This code does not have to be used with a PIR sensor it could be used with any analog sensor on 2 servos.   // GR0B Basic draw   - Robert Sturzbecher // This is my first Processing project. The purpose of this project is to render the values received back from a PIR sensor on 2 servos to give a crude image // server stepping on the Arduino is 3/180 if you use some thing different  // I have made the code very generic and flexable to suit any project that outputs (X Y Value) import processing.serial.*; Serial myPort;                                   // Create object from Serial class int val;                                         // Data received from the serial port int ServoStepping = 3;                           // Change this to match the Arduino servo stepping   void setup()  {   size(555, 550);                                //    ((180x3)+10)   String portName = Serial.list()[0];            // you will get a error here if port not found or in use. [0] is first serial port found   myPort = new Serial(this, portName, 19200);         background(0);  } void draw() {  String xString = myPort.readStringUntil('\n');  // read the serial port until a new line   if (xString != null) {                         // if theres data in between the new lines     fill(0);                                     // set fill to black     String[] SerialLine = split(xString,' ');    // split serial string line into array                                                  // string from arduino should line like this "X: 90 Y: 80 Val: 154"     int PosX = int(SerialLine[2]);     int PosY = int(SerialLine[4]);     int PIRVal = int(SerialLine[6]);     PosX = PosX *3;                               // zoom pixel size. 1/180 now equles a 3x3 size     PosY = PosY *3;     // define Color        int R = (PIRVal - 120);                   // you will need to customise these values to your project     int G = (PIRVal - 130);     int B = 25;          fill(R,G,B);                                 // set color          rect(PosX, PosY, ServoStepping*3, ServoStepping*3);                      // Draw colored square       //print some debug info to console     print(xString);         print("RGB: "+R+" "+G+" "+B);     println(" PIR:"+PIRVal);        } }
