Warning

This is the dev documentation for an unreleased version of MPF!

This is the documentation for MPF 0.53+, which is the “dev” (next) release of MPF that is a work-in-progress. Unless you’re specifically looking for this version, you probably want to use the version of documentation called “latest” which is for the latest released version of MPF. That documentation is at docs.missionpinball.org/en/latest.

Accelerometers

accelerometers:

An accelerometer is a device that measures proper acceleration; proper acceleration is not the same as coordinate acceleration (rate of change of velocity). For example, an accelerometer at rest on the surface of the Earth will measure an acceleration due to Earth’s gravity, straight upwards (by definition) of g ~= 9.81 m/s2. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero.

TODO: Add a picture of an accelerometer

Accelerometers in pinball could be used to measure a machine’s TILT, replacing the tilt bob, to measure vibration, or even the angle of the playfield at a given time.
