first of all, we need raw data, it could be AD or from other sensors, like the attitude data derived from six axis sensor.
Arduino101 is used here, and raw data generated from accelerometer and gyroscope.
Easier analytic to look so as a "curve" than pure raw data, we can basically use a "curve-painting" function to transform the data into waves.
pics are in the uploaded files, please check it out. (only one pic for a newbie, there are two more for the codes, but....)
