# Gyroscope
|
|
A gyroscope is a device to measure angular orientation and angular velocity. Traditionally it was a spinning wheel mounted on three gimbals.
|
|
|
|
Modern simpler devices make use of the coriolis effect and use vibrating structures instead of a rotating one.

## MEMS Gyroscope
|
|
A mems gyroscope makes use of a vibrating structure instead of a rotating structure, which makes it much simpler to manufacture.
|
|
|
|
A drive frame (yellow) is oscillated (usually at 10-40kHz).
|
|
When the sensor is rotated, the red mass is moved to either side and thus reducing/increasing the contacts to the blue sensing structure. See [How MEMS Accelerometer Gyroscope Magnetometer Work & Arduino Tutorial - YouTube](https://youtu.be/eqZgxR6eRjo?t=59) for more details.
