Arduino binary USB keyboard

I don’t know many (or any) people who think of characters and words in binary, but that might just be a limitation on my end. If you prefer binary, maybe this is something for you. If you just want to geek out, you’re welcome to stay here too. Using a 2-button macro-keyboard and some Arduino code, you can tap in binary and have the keyboard enter ASCII characters.

Basic QMK custom keyboard (with Ubuntu, Arduino Pro Micro)

After getting QMK to work, I thought it would be useful to document how I got it to work. This is starting from zero, using a Ubuntu live booting USB drive. Hardware I’m using a basic Pro Micro dev board. It uses the ATMEGA 32u4, and supports USB natively, which is what we need. When getting these, make sure to get Micro-USB (otherwise you have the chonky mini-USB), and the 5V/16MHz version.

Tiny USB keyboard with ATMEGA 32u4 - it works!

After a USB keyboard with an ATTINY85, a try at one with ATMEGA 32u4, I’m now at revision 2/3 for the ATMEGA 32u4 single key, USB keyboard. Overview Same as before: a simple USB keyboard with 1 key reprogrammable tiny mechanical keyboard key cheap enough to give away actually works debuggable The “cheap” aspect was mostly to justify making & buying some :). Hardware design Since the previous design mostly worked, I tweaked to make two versions.

Tiny (still-flakey) USB keyboard with ATMEGA 32u4

After making a USB keyboard with an ATTINY85 and noticing it wasn’t the “yellow of the egg”, I decided to try at making an ATMEGA 32u4 version. Overview What I was looking to make was (recap from previously): a simple USB keyboard with 1 key reprogrammable tiny mechanical keyboard key cheap enough to give away actually works debuggable The “cheap” aspect was mostly to justify making & buying some :).

Tiny (flakey) USB keyboard with ATTINY85

It would be neat to have a dedicated key to mute myself in these ever-present video meetings. I don’t have a lot of clues when it comes to electronics, but this was an interesting first project with a PCB of my own. Overview What I was looking to make was: a simple USB keyboard with 1 key reprogrammable tiny mechanical keyboard key cheap enough to give away The last item was probably just a self-justification - if I make a board, I might as well make a bunch of them.
