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.

  • A point to note- even a cheap keyboard will be way better than an actually home built one and it will cost a lot of time and money.

    But if you still want to make it, here are a few things:

    -An odinary microcontroller will not have enough of IO until it is huge. So you would consider to use a shift register which runs of I2C

    -You could use it with bluethoot.

    -You would like to use a HID(Human Interface Device) controller like Arduino micro or adafruit's Pro Trinket micrcontroller.

    Hope it helps.

    Do you think an arduino pro mini could work? I'm not sue if it has enough pins, But I've got one lying around here. I am also considering using a dirt-cheap keyboard's own controller and a custom matrix, give or take some keys. I'm making this for a raspberry pi thing you see, and I need something small, but not as small as some micro keyboards.
