THis project is basically changing the background color based on POT value.

I RUN The code in processing 2.2.1 (latest version) nothing is happening .

HeRE is the processing code
Code: [Select]
import processing.serial.*;
Serial myPort;

PImage logo;
int bgcolor = 0;

void setup(){
colorMode(HSB, 255);

size(logo.width, logo.height);
println("Available serial ports:");
//myPort = new Serial(this, Serial.list()[0], 9600);
myPort = new Serial(this, "COM3", 9600);

void draw(){
if(myPort.available() > 0){
bgcolor = myPort.read();
background(bgcolor, 255, 255);
image(logo, 0,0);


Anyone have problem or faced problem with project 14?

Is there anything wrong in my processing code? or all seem fine.

The background color takes forever to change for me not sure why.

I am having problem to change the background color instantly it change by after long period of time.


I'm running Ubuntu 14.04.
After installing Processing, the program works, but the backgroung did not change simultaneously.
When I move the potentiometer, background stays the same.
To change the Backgroung I have to stop the script in Processing, and run again.
Now it shows the new background.

Under Windows8 x64 it was working fine.
