Despite the buzzing, I moved on to working on the Arduino, because for the purposes of a proof of concept, the fingerboard was done. I discovered that the swiss machine headers I have are slightly different from the ones that are on TRAVIS I. For some reason the connection between the shield and the Arduino is fine when it is tilted to the extreme and does not work when it is sitting flat. I think it will be fine if the male to male headers are turned around.
