Zip the Drum Machine

  This is my attempt at building a drum machine from fritsl's walkthrough. I used two GM3 gearmotors from Solarbotics to drive the black tracks (also from Solarbotics). The project is centered around a Picaxe 28-pin project board. The microcontroller I used is a Picaxe 28X1.

  This is my first project with the Picaxe system, and I like it.  I had a steep learning curve, because this is the first microcontroller based robot I've actually wired and programmed. Interfacing to the project board was somewhat difficult with the documentation, but there are great walkthroughs on Lets Make Robots that made things easier. The Picaxe28 pin project board walkthrough was really helpful. Thanks fritsl.

  The SRF05 ultrasonic rangefinder is the main sensor for Zip. I just barely got it interfaced to the Picaxe 28X1, and am now working out the code to synchronize the sensor reading with the head looking left, right and forward. 

  You may have noticed the absence of Zip's drumsticks in the picture. I will add the drumsticks and mini geared pager motors after I have the sensing and navigation portions of the code functioning.
