Project 07 Problem : Buzzing without doing anything

Hardware The Arduino Starter Kit
1

Hello,

I'm encountering a problem with the Analog In values that makes the piezzo buzzing without touching anything.

The values shown by Serial.println when no buttons are on :
0
0
0
13
0
0
0
0
0
0
7
0
...

When I power the Arduino directly with a phone charger I don't have this problem.

Could my computer create "interferences" with the Arduino UNO ?

Thanks

yes, and some other thing.

Ok so it's kind of normal?
Because it's not making it easy to calibrate so I would like to find a solution.
