Graph Arduino Sensor Data with Java and JFreeChart

Make a data logger with your Arduino! Using the built-in serial port of an Arduino, we are able to communicate with a Java program. In this demo, a simple graphical user interface is made to graph the level of light seen by a Cadmium Sulfide sensor. This program could easily be extended to send data from an Arduino to a web site. Check back for more videos on this topic.

EDIT: Several of you asked about how to graph multiple sensors. I have a new video showing that, check it out here:

That video also shows how to do histograms, fourier transforms and more.
