I am using the Processing code found here http://remotedevice.net/project/sonar-tonebank/ with Processing 1.5.1. The error I am getting is






Exception in thread "Animation Thread" java.lang.NullPointerException
    at ddf.minim.javasound.JSMinim.getAudioInputStream(JSMinim.java:604)

    at processing.core.PApplet.run(Unknown Source)

I'd like to also point out that I haven't the faintest idea what I'm doing. So uh, when I want to run this, should I first upload the Arduino code found on the site, then present the Processing code and hope it works? What's the protocol here?
/huge noob sorry

(don't kill the noob)
