## PS/2 Keyboard

Would be great for “hobby” computers for example.  
Based on this library for Arduino IDE : [https://github.com/techpaul/PS2KeyAdvanced](https://github.com/techpaul/PS2KeyAdvanced) or this (a bit different) [https://playground.arduino.cc/Main/PS2Keyboard/](https://playground.arduino.cc/Main/PS2Keyboard/)

### Inputs

- `DATAPIN` (Pin on the Arduino) — the “data” pin.
- `IRQPIN` (Pin on the arduino) — the “clock” pin.
- …

### Outputs

- `OUT` (byte/character) — the description
- `PULSE` (pulse) — pulse whenever a key is pressed (NOT when it changes!)
- …
