I saw the Arduino QT PY while ordering online and thought it would be perfect for a single key keyboard, being only slightly larger than a MX switch.

This is made with just a QT PY, two wires, a 1kohm resistor and a Cherry MX Blue switch. It has a really small amount of code to act just like a normal key. I could also make it a macro.

I have included the .ino to flash the arduino with. It is currently set to be the button f, easily changed by changing the ASCII number from \" char button = 102;\" to something else. It could also be easily changed to a macro.

Below is the basic wiring and there is also a photo of how the internals are wired above.

There is a pinhole on the front of the keyboard case so that the reset/bootloader button can be pressed with a pin.

EDIT: I have now included code that was found on the below post by user paa36308. for Morse code support !
