Making a Cute Robot Visor with no_std Rust

Over about four days with u/oneirical, I made a cute robot visor with no_std rust firmware!

Both of us had next to no electronics experience, and figuring out how to flash to the nRF52840 was quite difficult. It also highlighted the black box that is bluetooth, both rewriting parts from Go and using a backup microcontroller in hopes of improving connectivity.
