Is there a sample GUI program in Java to Arduino?

Hello, I'm currently learning the codes of the "SerialTest.java" from the arduino playground. and I'm currently studying how to control an LED in arduino using the codes of the said program.

  1. I need a sample GUI program for java, in which I could send data thru bluetooth to arduino. :grin: glenn

Look at Processing - it is essentially Java, provides a simple user interface and can easily be used to communicate with an Arduino.
