## Wiring the Controller
As the following picture from the [amazing CuriousInventor PS2 Interface Guide](https://store.curiousinventor.com/guides/PS2) shows, PlayStation controllers use 9 pins:

| Pin # | Signal | Direction | Notes |
|-------|-------------|---------------------------|----------------|
| 1 | Data | Controller -> PlayStation | Open Collector |
| 2 | Command | PlayStation -> Controller | |
| 3 | Motor Power | | 7.5V |
| 4 | Ground | | |
| 5 | Power | | 3.6V |
| 6 | Attention | PlayStation -> Controller | |
| 7 | Clock | PlayStation -> Controller | |
| 8 | (Unknown) | | |
| 9 | Acknowledge | Controller -> PlayStation | Open Collector |
