Arduino/Teensy/Whatever Micro-controller DIY keyboard

fuzion_reaktor

Hello element 14, I am seeking the advice of whomever may offer it on how to make a DIY keyboard using, preferably an arduino pro mini, some other small type of arduino, or another type of micro-controller. Why I want to make a DIY keyboard you might ask? Reasons. Anyway, I need your help as all the websites and forums I have checked are either speculative, or deal with number-pads, not entire keyboards. There are no guides, nor much else I can find, and I'm not really into creating my own firmware with my current skill level. I plan to create my own PCB (not including the micro controller) and use hobby store micro momentary switches and generic diodes for this, along with whatever else you may suggest.

Anyway, thank you whomever can help me, and have a nice day.

  • That part was made easy for me because I was connecting an pre-existing matrix to the controller (from the Spectrum), then all I had to do was remap the keys through trial and error. Quite a few examples I have seen (Google 'diy keyboard matrix') are built using tactile keyswitches on a piece of proto-board, though my initial tests to find the best positions to solder the keyboard 'rows' to the controller were performed by simply shorting pairs of pins/pads with a piece of wire to see what keypresses were produced.

    So, for the matrix you used everything was just simple rows and columns? I've looked inside a keyboard or two and the matrices seem more like a maze than a circuit.
