Leds Blink To Music with BeatWrite and Arduino

HyperHitesh

Hey everybody. So I got this code from an Instructable at and I don't know how to put all the processing and arduino libraries together and stuff. But more importantly, I'm getting lots of errors. PLEASE help me out with the code and the errors( and with connecting the libraries- processing and the Arduino IDE). The code is at

/**
  * This sketch demonstrates how to use the BeatDetect object in FREQ_ENERGY mode.<br />
  * You can use <code>isKick</code>, <code>isSnare</code>, </code>isHat</code>, <code>isRange</code>, 
  * and <code>isOnset(int)</code> to track whatever kind of beats you are looking to track, they will report 
  * true or false based on the state of the analysis. To "tick" the analysis you must call <code>detect</code> 
  * with successive buffers of audio. You can do this inside of <code>draw</code>, but you are likely to miss some 
  * audio buffers if you do this. The sketch implements an <code>AudioListener</code> called <code>BeatListener</code> 
  * so that it can call <code>detect</code> on every buffer of audio processed by the system without repeating a buffer 
  * or missing one.
  * <p>
  * This sketch plays an entire song so it may be a little slow to load.

And I get the error like this :

I'm sorry if this is causing you a headache. But I'd really appreciate it if you could break down the code for me and solve the problem. I have faith in you guys. Like seriously. Thanking you in advance. geekgeekout@gmail.com

I got that too. I changed the 1 to 0 in this line of code and mine's working now. Change from this: arduino = new Arduino(this, Arduino.list()[1], 57600); To this: arduino = new Arduino(this, Arduino.list()[0], 57600);
