Here are some Arduino sketches I wrote for the Stemtera breadboard.
As this code is simple enough I would consider it "Arduino sample code", you may use the contents of this directory for any purpose as public domain under the Creative Commons Zero license. If you redistribute the source code to another person, rather than merely reusing the code in a project, I would appreciate if you would add a note crediting Andi McClure <andi.m.mcclure@gmail.com> as the original author of the code (however this is not a legal requirement).
