I have an old “left handed mini keyboard” from my XP days.
I can’t find a windows 10 driver.
My plan is to get an arduino which as a USB-A port (same as what you see on computers) and that will allow me to plug this into the keyboard. Or more so: Plug the keyboard into the arduino.
Then I write some code. It looks for buttons being pressed on that keyboard and transcodes them into what I want them to be.
Shouldn’t be too hard. But I don’t know how to find the “hat” (or entire board) in the arduino world.
Unfortunately, a majority of Arduino boards don’t have native USB peripherals onboard. In short an Arduino probably wont be your best bet here.
Your best bet might be to pull apart the keyboard and tap into the outputs from the buttons - there are a few configurations for keyboards - some setup in a grid and some that use whats called a multiplexer to handle button inputs. Zack Freedman has an awesome video on making one here: I Invented a Keyboard and Snapped it in Half (MiRage Mech Keyboard) - YouTube
Definitely applicable to this project!
