Interface and Application programming

For this week I decided to work on my application in Java. My plan is to create a circle that grows bigger when the sensor has a bigger value. Finally when the value gets high enough the circle will grow a smiley face. So far I have been working on learning Java using DR. Java. Also I have been using video tutorials from http://www.javavideotutes.com/lessons. I highly recommend them for anyone who wants to learn Java. However in order to read data from the serial port I needed to use an extension. Javax.comm. Once I finally managed to get the extension into the library area I started to try and use it. However I ran out of time and have yet to finish my program. When I came back later I discovered the problem. Javax.comm is for Windows not Mac OS X. I found another extension RX/TX which does the same thing. However I did not know how to use it and still have not figured it out. Since then I decided to program the application in Processing because it is simpler to learn in a limited amount of time. After figuring out how to read serial data and create shapes I managed to write a program that changes the color of a circle depending on the value of the sensor.

import processing.serial.*;

Serial serialPort;
int col = 0;
int umm = 0;
void setup() {
 size(500, 500);
 background(51);
 noStroke();
 smooth();
 println(Serial.list());
 serialPort = new Serial(this, Serial.list()[0], 9600);

}

void draw() 
{
  color ahh = color(255, 0, 0);
  color yay = color(0, 255, 0);
  ellipseMode (CENTER);
  ellipse(250, 250, 100, 100 );
  while (serialPort.available() > 0) 
   {
    umm = serialPort.read();
   }
   if (umm >10); 
   {
   println(umm);
     if (umm > 225) 
     {

        fill(ahh);
      }
     else if(umm >6)
     {
       fill(yay);
     }
   }
}
