It is good to build a sound tracking system, that makes the motor moves to the direction of the sound. There are posts here called sound localization using arduino.http://hacknmod.com/hack/diy-sound-localization-sensor-with-arduino/
however, there is probably a simpler way to do it. It is simply using a circuit that compares 3 audio level and rotates the motor to the strongest source.
Here you do not need microcontroller, or programming.
I know that PIC programming does not appeal to some DIY makers..
3 MICs collect sound, amplified by simple op-amp for each mic.
3 signals fed into a comparator circuit, which ensures motor moves towards the direction where mic received strongest signal.
I did not design the circuit yet, although it should be fairly easy to do that even on a simulation like workbench.
suggested components can be
3 X condencer mic
2 X LM324 Quad-opAmp (3 are used as op amps and 3 used as comparators)
any H-bridge motor control circuit.
small DC motor.
---final note
Circuit can be replicated for vertical movement to have 2-axis audio tracker.
Hope you like the concept.

<p>I like the concept, but specific instructions would be better. Always easy to leave important details out unless you've actually made it.</p>
<p>Check out this older article claims it does it w/no programming using concept similar to what the guy is trying to do.</p><p><a href="http://www.best-microcontroller-projects.com/sound-origin-direction-finder.html" rel="nofollow">http://www.best-microcontroller-projects.com/sound...</a></p><p>I would think that some company would be putting out off the shelf shields by now.</p>
@goldenshuttle, I've been searching the web for sound localization and found you post, you say no programming, right? I may has read using the PIC, are you saying this uses a PIC to controll your idea?<br><br>DO you mind throwing me a bone , I've never used a pic before can you give me a brief overview or a link to study it further, thank you.<br><br> And if you do use a pic with this idea do you mind giving example programming on it thank you very much.<br><br>Merne<br>
