Bitty Controller will not magically know how to control your machine.... you have to do some programming of the other device for it to work.

Bitty Controller lets you remote control a Bluetooth connected device which uses a micro-controller or computer like a BBC micro:bit, Arduino or Raspberry Pi. It provides a choice of user interfaces including several digital switches for switching things and and off, a dual d-pad controller, an analog touchpad for fine control and an enhanced UI which includes support for up to 5 sensors and has an extra button.

The Bitty Software blog contains code examples and further information.
