Hello,
I buy a Sound sensor for Arduino on dx.
But I have a problem.
I use analog Read and I see my sensor stay at 18-19 even if there is no sound or sound.
I don't understand.
Sorry I'm beginner and sorry for spelling mistake.
Thanks
Code:
int U;
const int sensor = 7;
void setup()
{
Serial.begin(9600);
}
void loop()
{
U = analogRead(sensor);
Serial.println(U);
delay(100);
}
