The Revenge of the Yellow(Arduino) Drum Machine

I am working on an Arduino powered Yellow Drum Machine. I have all of the physical parts functional. Now I am working on the code. I have just completed translating all of Frits's songs to the format I need. Now I just need to coordinate the control structure to allow it to autonomously move around, make decisions, and to play its little heart out. More later...

I needed to have a larger base to attach the solenoids to.  The gray material is a scrap plastic I got from ordering polystyrene for vacuum-forming.  I don't know what type it is, but it it fairly brittle.  I cut it out using a jig saw

Here it is attached to the base with self-tapping screws. 

.This is a closeup of the oid connection to the hihat drum stick.

        This is the robot base I used.  It can be found be searching for      "Six leg walking type gearbox kit Elenco 21-13".

I don't know how specific anyone wants me to get.  I killed two of the Radio Shack sound recorders.  I'm not sure what happened.  They worked for a while, and then the playback just died.  So I ended up using this Sparkfun recorder/playback breakout board.  It is working fine as of now.

I tried the Sparkfun sound sensor, but couldn't get it to work.  I read a post that this sensor was very good, so I built it from scratch.  It works great!  

My little drum machine uses the PING))) and a CDS photocell and the sound sensor to react to the environment.  It chooses songs based on the data it has collected about its surroundings.  The gearbox base gives it a fun movement - it kind of wobbles and drifts as it moves.  The gearbox also has little legs you can use instead of the disk wheels.  I have programmed in several behaviors.  I used a timer library to call random behaviors every 10 seconds.  30% of the time it will search out an object and then beat a funky beat.

I will continue to work on the code.  I would like to use the piezo speaker to play little melodies as it moves around its environment.  I think that's it unless anyone is interested in more specifics.
