How do you interface with your hardware? MPF supports a lot of platforms and you can add your own by implementing the platform interface (in python). Alternatively, you could implement the Backbox Control Protocol (BCP) and only use MPF-MC (MPF media controller). Bother ways are possible. The former is probably easier and more flexible. Here is a short overview over the architecture: http://docs.missionpinball.org/en/dev/displays/mc/index.html of MPF and MPF-MC. You can find a simple platform implementation here (for the RPi): https://github.com/missionpinball/mpf/blob/dev/mpf/platforms/rpi/rpi.py. If you want to maintain it separately from MPF we also support external platforms in another module: https://github.com/missionpinball/mpf-demo-platform.

MPF is not running on the Arduino. The Arduino will interface to a PC (such as the up board used in TNA) via USB. There are multiple ways to connect MPF to hardware platforms. Usually, the platform author writes a few lines of python glue. Alternatively, the platform can implement the existing serial LISY protocol (http://docs.missionpinball.org/en/dev/hardware/lisy/protocol.html).

In this case where the game logic runs on the Arduino instead of in MPF more options exist. Implementing BCP (as mentioned above) or USB HID are a few of them. Writing a few lines of python glue is probably still the cleanest option but other ways exist. This is certainly not the primary usecase for MPF.
