MIDI-Controlled Slide Whistle

Added some instructions (to be finished soon), and (I hope) a full Bill of Materials.  Minor Corrections/Additions to the STL/STEP/DXF zip file.

Added a build video in the project details!

Cleaned up the code a little bit:

--- took out some of the bits that were hanging out from other instruments).  

--- Have also modularized the step-taking to be a function call to keep the forever loop looking a little cleaner.

Soon:

Plan on making the instructions a bit more detailed, and clearly defining the Bill of Materials.  Also need to add in the step file/build files the little laser cut "clip" piece that helps hold the two halves of the base plate together.

First build of this system - with some pre-build design iteration.  

Features to add:

- Limit Switch
