This is a guide to make an LED flashing circuit that "beats" to an mp3 file on your computer, which can add an awesome effect to any sound-related device, or even your room (if you extend the concept with LED drivers or plenty of resistors/transistors).

The LED flashing circuit makes use of the Minim audio library and the Arduino program Processing to analyze sound, producing a response based on a snare drum hit, a bass drum hit, and a hi-hat hit from the percussion of the audio file.

Schritt 1: Parts/Tools Needed

Here is what you'll need to make the LED beat flashing circuit:

Hardware:
1. An Arduino microcontroller board. There are many versions of the Arduino, but I would recommend the Arduino Duemilanove. You can buy one online for around $20.
2. Three LEDs (different colors preferred, so you can see the difference in beats easier - I used a red, yellow, and green LED)
3. Three resistors (depending on your LEDs, the resistor value will be different - check the ratings on the LEDs to see what resistance corresponds to their maximum brightness, without burning them out)
4. A solderless breadboard
5. Some wire, to use as leads from the Arduino to the LEDs/resistors on the breadboard
6. A computer
7. A USB cable (A to B)

Software:
1. Arduino Software Environment
2. Processing Software Environment
3. The "arduino" library for Processing
4. The BeatWrite / BeatListener code from the minim JavaSound library examples

Download links for the software will follow in Step 3.

Also had the &quot;the package &quot;cc&quot; does not exist issue. To fix -- In the Processing Editor, select &quot;Sketch&quot; &gt; &quot;Add File&quot;, then just select the &quot;Ardunio.jar&quot; file. Should work! <br> <br>I also got &quot;ArrayIndexOutOfBoundsException&quot; -- To get this fixed; <br> <br>Changed line 35 from; <br> arduino = new Arduino(this, Arduino.list()[1], 57600); <br>To; <br> arduino = new Arduino(this, Arduino.list()[0], 57600); <br> <br>And then it works!! :) <br>
<p>Thank you!</p>
<p>I got it working but is there any ideas on getting it to play with live streaming audio from either a player or line in</p>
<p>Have you had any luck with this? I'd love to have to do that as well. Maybe use an a microphone to pick up the surrounding audio and have it analyzed by processing? That seems crude, but it's what comes to mind at the moment. </p>
<p>Worked great for me, thanks for the awesome tutorial! Fun little project that I plan on expanding into future projects. The only comment I have is that I was running into some problems communicating with the arduino initially. </p><p>In the Beatwrite code be sure to edit the following line of code: </p><p> arduino = new Arduino(this, Arduino.list()[2], 57600);</p><p>The number in brackets (2 in this example) is the com port that the arduino is on. I'm running a mac, so it wasn't listed as com 1,2,3 like it is one a windows machine. I simply used trial and error starting at 0 and eventually it worked when I tried 2. After I got that sorted out, it worked great. </p><p>I also attempted to play a .m4a audio file and the program crashed. I'm not sure if there's another format that can be used, but I plan on doing further research. </p>
<p>I everybody! I keep getting an error that the serial port is on bluetooth even though we have it on usb...did anybody run into this issue as well? </p>
<p>yes i did, the way I fixed it was by changing the line </p><p>arduino = new Arduino(this, Arduino.list()[1], 57600);</p><p>on the processing program to 3 so it looks like this</p><p>arduino = new Arduino(this, Arduino.list()[3], 57600);</p><p>this may be different for you but you can find out by going to arduino program and selecting the menu tools - serial port and then looking to see what number down the list /dev/cu.usbmodem1411 is but when you are counting ignore the /dev/tty. one as these are a different type of port</p><p>And if this doesnt work message me</p><p>Hope this helps</p><p>MacMan</p>
Hey guys, I fixed the &quot;the package &quot;cc&quot; does not exist. you might be missing a library.&quot; error! ITS SUPER SIMPLE! Just go to /libraries/arduino/library/ and rename the Arduino.jar to arduino.jar with a lowercase :)

I have this error and this did not help
Help! Hope someone is looking at this. Worked on an error all day. Can't get it. When the file BeatWrite is started, get the error, &quot;import does not name type.&quot; Appreciate any help you can give me.

I've been working on this for a bit now, and can't seem to get it to work. I believe the Processing app is trying to communicate with the Arduino board via bluetooth, and I need it to speak via USB. I would appreciate any feedback. Thanks. <br> <br> <br>- java.lang.RuntimeException: Error opening serial port /dev/cu.Bluetooth-Modem: Port busy

<p>I need help. My led won't light up.I hear the music in the processing. I checked and made sure they led are working. How do i use processing to connect with arduino</p>
<p>Me too.</p>
<p>Hi. Does anyone know how I can extend the length of time each LED is on for? I am trying to hook the outputs to a relay module and feed it to a traffic light. The period of each pulse is way too fast at the moment and I am looking to reduce it. </p>

<p>i have been trying to get this software to works for the past couple days now and it keeps saying &quot;the package &quot;cc&quot; does not exist...</p><p>I understand that the libraries have to be within the sketchbook folders for the program to find them but i guess i don't know which file is missing or exactly how it is supposed to go if someone (hopefully the poster?) could screenshot the folders and how they are supposed to look or describe the order of files within files that would be awesome. I've been moving things around for a while and i have already tried renaming Arduino to arduino, no luck.</p>
<p>Hello there!<br> Can I change the music into one of the songs of SKRILLEX like the CINEMA or the Rock and Roll song? and also how will I code it if I'm going to use that song. Thanks :-)</p>

Hi I Was wondering if you are able to add more channels to the program so you are capable off having 8 leds flashing away
I have tried so many different ways to do this and was just about to buy a pre built kit and yours worked!! Because I couldn't get the pre built kit here in time I needed something as proof of concept. Thanks heaps!!
mine highlights this: <br> arduino = new Arduino(this, Arduino.list()[0], 57600); <br> <br>and wrote that they could not register dispose + 0 for processing. <br>anyone knows what went wrong? <br>
Here is my code: <br> <br>/** <br>* This sketch demonstrates how to use the BeatDetect object in FREQ_ENERGY mode. <br> <br>* You can use isKick, isSnare, isHat, isRange, <br>* and isOnset(int) to track whatever kind of beats you are looking to track, they will report <br>* true or false based on the state of the analysis. To &quot;tick&quot; the analysis you must call detect <br>* with successive buffers of audio. You can do this inside of draw, but you are likely to miss some <br>* audio buffers if you do this. The sketch implements an AudioListener called BeatListener <br>* so that it can call detect on every buffer of audio processed by the system without repeating a buffer <br>* or missing one. <br>* <br> <br> <br>* This sketch plays an entire song so it may be a little slow to load. <br>*/ <br> <br>import processing.serial.*; <br>import ddf.minim.*; <br>import ddf.minim.analysis.*; <br>import cc.arduino.*; <br> <br>Minim minim; <br>AudioPlayer song; <br>BeatDetect beat; <br>BeatListener bl; <br>Arduino arduino; <br> <br>int ledPin = 12; // LED connected to digital pin 12 <br>int ledPin2 = 8; // LED connected to digital pin 1 <br>int ledPin3 = 2; // LED connected to digital pin 0 <br> <br>float kickSize, snareSize, hatSize; <br> <br>void setup() { <br>println(Arduino.list()[0]); <br>} <br> <br>void draw() { <br>background(0); <br>fill(255); <br>if(beat.isKick()) { <br>arduino.digitalWrite(ledPin, Arduino.HIGH); // set the LED on <br>kickSize = 32; <br>} <br>if(beat.isSnare()) { <br>arduino.digitalWrite(ledPin2, Arduino.HIGH); // set the LED on <br>snareSize = 32; <br>} <br>if(beat.isHat()) { <br>arduino.digitalWrite(ledPin3, Arduino.HIGH); // set the LED on <br>hatSize = 32; <br>} <br>arduino.digitalWrite(ledPin, Arduino.LOW); // set the LED off <br>arduino.digitalWrite(ledPin2, Arduino.LOW); // set the LED off <br>arduino.digitalWrite(ledPin3, Arduino.LOW); // set the LED off <br>textSize(kickSize); <br>text(&quot;KICK&quot;, width/4, height/2); <br>textSize(snareSize); <br>text(&quot;SNARE&quot;, width/2, height/2); <br>textSize(hatSize); <br>text(&quot;HAT&quot;, 3*width/4, height/2); <br>kickSize = constrain(kickSize * 0.95, 16, 32); <br>snareSize = constrain(snareSize * 0.95, 16, 32); <br>hatSize = constrain(hatSize * 0.95, 16, 32); <br>} <br> <br>void stop() { <br>// always close Minim audio classes when you are finished with them <br>song.close(); <br>// always stop Minim before exiting <br>minim.stop(); <br>// this closes the sketch <br>super.stop(); <br>} <br> <br> <br> <br> <br> <br>I get an error on this line: if(beat.isKick()) { <br> <br>Here is the error: NullPointerException

my best settings came as: <br> <br> beat.setSensitivity(1); <br> kickSize = snareSize = hatSize = 500 <br> <br>time to rig it up to some bridge rectifiers, isolators and some A/C lights
It says serial does not run in 64-bit mode? Can anyone help me? <br>
Well now I fixed that... But now it's saying: <br> <br>&quot;NullPointerException&quot; on processing <br>An highlighting the line &quot;song = minim.loadfile(&quot;mysong.mp3&quot;, 2048);&quot;
Well, I fixed the &quot;Cannot find a class or type named 'BeatListener'&quot; problem... On my own. <br>But I would appreciate it if someone would help with arduino. When I try to upload it, is says &quot;avrdude: stk500_getsync() : not in sync: resp=0x30&quot; What exactly does that mean and how do I fix it; because I think it has something to do with &quot;ArrayIndexOutOfBoundsException: 1 <br>WARNING: RXTX Version mismatch <br> Jar version = RXTX-2.2pre1 <br> native lib Version = RXTX-2.2pre2 <br>Exception in thread &quot;Animation Thread&quot; java.lang.ArrayIndexOutOfBoundsException: 1 <br> at sketch_jan20a.setup(sketch_jan20a.java:59) <br> at processing.core.PApplet.handleDraw(Unknown Source) <br> at processing.core.PApplet.run(Unknown Source <br> at java.lang.Thread.run(Thread.java:662)&quot; on processing. <br>(btw: &quot;sketch_jan20a.&quot; is the name of the processing page I put the code on) If someone could help with either or both of these, it would be much appreciated!
On processing, it says <br> <br>&quot;Cannot find a class or type named 'BeatListener'&quot; <br> <br>How do I fix this? What am I missing? No ones' answers are helping me.
I need help, when I press the run button in processing it says No library found for cc.arduino <br>Libraries must be installed in a folder called &quot;libraries&quot; inside the &quot;sketchbook&quot; folder. <br>I've found the libraries folder in the arduino-1.0.3 folder but I cant find sketchbook folder
