a Morse code to plaintext keyboard body designed for a raspberry pi pico microcontroller and a momentary button. the button needs to be hot glued in place for the best fit and soldering is required to complete the project. a copy of the python text to be loaded onto the pico along with circuit python and the adafruit hid library can be found below (i don't have a github so it may need refactoring)
