Plane demo
The goal of the application is to show how accelerometers can be used to measure the tilt of
an object, where the tilt is a static measurement and where gravity is the acceleration being
measured. The force of gravity is used as an input to determine the orientation of an object,
calculating its degree of tilt. The x, y, z acceleration values are elaborated on the PC
application to evaluate the rotation angles of a graphical object (Plane). The behavior of the
demo is intuitive, as the graphical object on the PC monitor moves according to the
movements impressed on the MotionBee™ module.
