Hey there!!
I'm so sorry for this question, I'm just starting playing with my Arduino UNO R3
I'm using a microphone module (FC-04) and, but Im getting just 2 values:
35 when sound not detected
1023 when sound detected.
What can I do? u_u Im very lost. Thank you!
Very simple code:
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.println(analogRead(A3));
}
That is exactly how that sound module should work.
What do you want to do and what did you expect that module to do?

To see why your module works like this.
Ohhhhh, the sellman told me that it was used to get frequencies and stuff. I will need a microphone to create an speech recognition hardware, but I think I will need another.
Thank you very much for your time! And sorry for the dumb question. Night
Just a note to say you can't do speech recognition on an Arduino anyway, there is not enough memory. You need to do this on another processor which you can attach the the Arduino as a shield.
