## PS/2 keyboard as 4 USB-joysticks

![PS2-adapter](https://raw.githubusercontent.com/mcgurk/Arduino-USB-HID-RetroJoystickAdapter/master/Images/ps2-keyboard-adapter.jpg)

Needs Atmega32u4 (e.g. Arduino Leonardo).

Needs custom ps2-library (PS2Keyboard_mcgurk.zip, unzip to libraries-folder).

Clock-signal must be in pin 2 (because of interrupts).

Edit button assignments manually.

Joystick 1:
arrows = up/down/left/right
R-ctrl = a
alt gr = b
enter = start
R-shift = select

Joystick 2:
W/S/A/D = up/down/left/right
L-ctrl = a
L-alt = b
tab = start
L-shift = select
