 ==Overview==
 Sometimes the accelerometer sensor produces quite a lot of noise (that is, undesired data). This can be perceived, for example, by putting the device on the table while observing the produced data. The values should stay more or less stable while the device is on the table. However, this is not the case because of the noise.

The technique used in this snippet is to create a [http://en.wikipedia.org/wiki/Circular_buffer circular buffer] (a.k.a. a ring buffer) and continuously fill it with data produced by the sensor. As a result, "raw" sensor data is not used, but  an average value of the buffer contents is used instead.
