The gyroscope is capable of measuring how quickly the phone is being turned. It measures the rate of rotation of the phone and returns values in radians per second about the x axis, the y axis and the z axis. This rate of rotation is also known as the Angular Velocity, so the gyroscope can tell us the speed of rotation of the phone. By extension, if the speed of rotation is any number greater than 0, we can infer that the phone is being turned.
To add a Gyroscope to your app:
Go to the Blocks tab of your project
Find the Sensors drawer of blocks and click on the ⊕ symbol to add a Sensor to your app
Select Gyroscope from the menu that pops up
You will see a settings panel where you can set:
The Name of the Gyroscope
Whether the Gyroscope is Enabled
You can either confirm your choices and create the Gyroscope, or delete the Gyroscope.
You will see the sensors you have added to your app underneath the Sensors section of your blocks.
If you click on the ⚙ icon next to your Gyroscope, you will be able to edit its settings as seen in the panels above. You can click on your Gyroscope's name to access its drawer of blocks.
Whenever the phone is turned, or rotated, the
Changes event will fire.
By default the gyroscope sensor is turned on, but the
enabledproperty can be used to read and write new values to the gyroscope, thus allowing you to turn it on or off.
