2. touchdevelop api gyroscope o gyroscope sensor determines rotational velocity of the device in each axis. o use values obtained from the gyroscope sensor to determine the orientation of the device in space o if you are interested in determining the attitude (yaw, pitch, and roll) of the device, use Motion o gyroscope sensor is not required for Windows Phone devices; your phones do not have it

4. touchdevelop api apis o Senses→has gyroscope Indicates if the gyroscope is available on the device Senses→has gyroscope o Senses→has motion Indicates if the motion can be computed on the device. Motion requires accelerometer, compass and gyroscope. Senses→has motion o Motion→gravity Gets the gravity vector associated with this reading. Motion→gravity o Motion→acceleration Gets the linear acceleration of the device, in gravitational units. Motion→acceleration o Motion→yaw Gets the yaw of the attitude in degrees Motion→yaw o Motion→pitch Gets the pitch of the attitude in degrees Motion→pitch o Motion→roll Gets the roll of the attitude in degrees Motion→roll o Motion→rotation speed Gets the device rotation speed in degrees per sec. Motion→rotation speed o Motion→time Gets a timestamp indicating the time at which the reading was calculated. Motion→time
