Arduino PS2-to-USB

This project allows you to use Arduino as USB adapter for PS2 keyboards like IBM model M

Installation and usage

To use Arduino as adapter you should first connect PS/2 keyboard cables wires to arduino

V+    to  VCC
GND   to  GND
Data  to  pin2
Clock to  pin3

Then connect arduinos USB to PC with any suitable cable and upload the code as a normal scetch to arduino

• First release confirmed to be working with Windows7 and Windows10. Most likely works on most operating systems with some degree of accuracy with keymaps

• Requires arduino with USB host cababilities. Confirmed working on Arduino Pro Micro

• Currently only supports Finnish keymap with 104 keys or less. If you want to help adding more keymaps feel free to email me

• Pausebreak key toggles numpad numbers to work as mouse (0 and 5 for mousebuttons)

Todo and upcoming changes

• Code cleanup and refactoring
• Add support for capslock etc. lights
• Add support for more keys
• Add support for en-us keymap
• Add easy-to-configure remapping system
• Convert code from scetch to library form
• Better mouse emulation support
