# M2 VIN Extraction

#### Items Used

* 1x [M2](https://www.macchina.cc/catalog/m2-boards/m2-under-dash)
* 1x Car with OBD-II Port

#### M2 Sketch

#### Collect VIN

With the vehicle running, plug M2 into the OBD-II port. M2 should flash yellow lights as it queries for the VIN, then light up green for success or red for failure. In either case pressing button 1 will make M2 try again, writing a new text file each time.
