Calculation of frequencies with data from an accelerometer [FOURIER TRANSFORM]

Job ID: 35151249

Budget: $10 – $30 USD

Look, I'll tell you, so that you pay attention please:

They made us install an application on our cell phone that works like an Accelerometer, we opened the app, put the cell phone on the table, they put on a Queen song and we did the following.

I show you on video what was done:

In the end, a data file is generated in this way (attached file 'DATA').

With this you have to do the following:
1. Demonstrate with data that the cell phone did not move, based on the accelerometer data. With F=m*a.
2. What is the frequency between the beats of the song. Using fourier transform.
