When this box is connected to your computer, it behaves like a USB HID Keyboard. Press a button and it types a letter! It’s really simple and easy to manipulate the code so you can output single characters or string multiple characters together to execute commands! The LEDs also light up each time you press a button.
If you remember the Desk Of LadyAda stream on May 23, 2017 you may remember this project. Phil originally wanted a way to switch between scenes in WireCast using a custom trigger controller. Limor had the idea to prototype this using Circuit Python and an Adafruit Feather M0 Express.
Circuit Python Keyboard Emulator
I designed a simple enclosure to house a few 24mm arcade buttons (with built-in LEDs!) and the Adafruit Feather M0 Express. I made a few different layouts, ie. two by two, three by two, four by four, etc. It’s parametrically driven so it’s really easy to make custom layouts. I put together a Layer by Layer tutorial that demos how it works. I think it’s pretty neat. Hope you find it useful for your projects.
