- You will need one [Atmega32u4](https://pt.aliexpress.com/item/New-Pro-Micro-ATmega32U4-5V-16MHz-Module-with-2-row-pin-header-For-Leonardo-best-quality/32273120508.html?spm=2114.13010608.0.0.Uv843y&detailNewVersion=&categoryId=400103) (e.g. Arduino Leonardo).

## 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 |
|

**You are advised not to rely on wire colors, but rather on pin positions**. The wires in the image come from an official Sony controller, I expect their colors to be fairly consistent among all Sony controllers, but you shouldn't really trust them.
