Hey. Can someone help me figure out how can I reduce the deviation from sound measurements?
I am using arduino nano circuit . 7V powering arduino nano and sound sensor and from arduino nano A0 is connected to analog sound sensor pin.
this is sound sensor I am using
as you can see in the picture readings are very random and picture was taken in complete silence. I am trying to make arduino sound reactive LED and used the code this guy provided: Music Reactive Desk Light || DIY - YouTube
But it did not work so I am trying to write a simplified version of this on my own
Screens shots can not have text selected, need to be figured out what is what, etc.
And of course links to the datasheet of the sound sensor, circuit diagrams, and other relevant info is missing. Please read this as well.
