Description

it's a usb keyboard with play/pause, next, previous buttons, and a volume knob. No special drivers are needed, just plug it into an usb port and it works.

The atmega88 inside registers as a HID device, specifically, a keyboard with only a few multimedia buttons. This way it will work out of the box on most OS.

updated circuit pic and firmware instructions
Pengu MC • 11/04/2014 at 09:50 • 0 comments

I accidentally had the old circuit pic up on the site, so that's been fixed to reflect the actual schematic.
I also forgot to mention that you need the vusb files to build the firmware. Instructions have been updated in the readme on github
