Nice!  I wonder if I can make that work with a Teensy 2.0 that would fit in
the case.

I'm planning to use a Arduino Pro micro (https://www.ebay.de/i/272467411507?chn=ps&norover=1&mkevt=1&mkrid=707-134425-41852-0&mkcid=2&itemid=272467411507&targetid=527969225193&device=c&mktype=pla&googleloc=9041953&poi=&campaignid=1669295758&mkgroupid=63847509999&rlsatarget=pla-527969225193&abcId=1139676&merchantid=113833088&gclid=EAIaIQobChMI9NOgmL_u5gIVB_hRCh07kQ8nEAQYASABEgIATPD_BwE)
which should easily fit into the case. I used the larger Arduino because the Pro
micro didn't arrive yet. The code should work without modification on the smaller
one.
