Now that is just fascinating, but what is the purpose of that breadboard?
It is the display and switch I2C expansion interface for my Bat Bass project. It is to allow Sam, who has cerebral palsy, to continue to play a rather simplified Bass Guitar. He has a degenerate condition which will slowly get worse. He is having trouble holding down strings now so I built this using two bungy chords. The bass can be set to any key and one string will sound the note given by the key switch last pushed. The second string is always a fixed ( programmable ) number of semitones above the first string, typically a fifth.
I am part of the Drake Music Labs (North) where geeks like me and disabled people work together to produce accessible instruments. We meet in Manchester, next meeting https://www.eventbrite.co.uk/e/dmlab-north-west-meetups-tickets-44144134294
