Good afternoon. First of all my apologies in case the topic does not go here. I'm new to the forum and don't control electronics too much.
I need your help. I am making a "sound frequency detector", something like a "guitar tuner" that detects each musical tone.
The operation would be that if my voice emits a DO, I want a red LED to light up; if you issue a RE I want a blue LED to light up; if you issue an MI I want a green LED to light up ...
I don't know where to start ... any help will be welcome.
The videos that I have seen on youtube do not explain code or components.
I have purchased MAX4466 microphones.
I started with the KY38 module but it does not help me, since that only detects hits, I need it to detect if it is a DO, RE, MI ...
Many thanks
