11. Accelerometer

On board ADXL345 accelerometer is used to

measure acceleration in three axis: x- y- and z-.

The acceleromer’s function is dened by the user in

the program loaded into the microcontroller. Communication

between the accelerometer and the microcontroller is performed

over the I

C interface.
