The path to getting my USB keyboard talking with my Ardunio took a few twists and turns. My internal patience-meter said "Time's up!" and I decided to take a different approach and switch to an ESP32-based microcontroller.
And the rest, as they say, is history! I'm an electronics noob so it's a big personal achievement to finally get this working...and I learned a lot along the way!
_Thanks for watching, and as always I welcome any feedback or ideas for future projects!_
