Hi! I made it almost all the way through getting this thing made without any real problems. I got to compiling the Nybble.ino file and I get a bunch of compile warnings. It uploads anyway, but it only semi works. I don't know if the warnings and the behavior are related, but it's the only indication of something going wrong. The only thing I can think of where I deviated from the assembly instructions while doing the software was at 3.2.2: Install by adding .Zip library. After unzipping the whole repository, the individual libraries it says to add weren't in zip files, so I zipped them myself and added them that way. Thank you! I'm excited to get it working.
