Thanks http://spikenzielabs.com for the 64 button shield!. Don't laugh too much:)
My project is to have a bunch of button on the surface of a plastic bucket. Plus each button will have an associated LED. So there will be two matrix interfaces to be built. Still working on the buttons.
Needed a way to get the 8 pin matrix onto a board that I could plug the buttons into.
All the nodes report in as expected. I can see them in serial mode.
My first real soldering project that quickly descended into despair as problems mounted. Figured out that using the bare metal wire as rails on the front and back of the PCB did the trick.
