This is a DIY controller box with arcade buttons and an Adafruit Feather M0 Express. When this box is connected to your computer, it behaves just like a USB HID Keyboard. Press a button and it types a letter! It's really simple and easy to manipulate the software so you can output single characters, or string multiple characters together to execute commands! The software is written in CircuitPython. Check out the full tutorial for this project on the Adafruit Learning System - https://learn.adafruit.com/arcade-button-control-box/overview
