Sound Detection Sensor Board FC-04 for Arduino

Sound detection sensor FC-04
Condition: brand NEW
Size: approx. 32mm x 16mm
Working voltage: DC 4-6V
Signal output indication
Single channel signal output
Main chip: LM393
Can be used for Acoustic control light


Code:
/*
This is the code to make a LED blink with the music.
You have to set the threshold so it' sensible enough to make the led blink.
You connect an LED to PIN13 and the Sound Sensor to Analog Pin 0
*/
int led = 13;
int threshold = 500; //Change This
int volume;

void setup() {
Serial.begin(9600); // For debugging
pinMode(led, OUTPUT);
}

void loop() {
volume = analogRead(A0); // Reads the value from the Analog PIN A0
/*
//Debug mode
Serial.println(volume);
delay(100);
*/
if(volume>=threshold){
digitalWrite(led, HIGH); //Turn ON Led
}
else{
digitalWrite(led, LOW); // Turn OFF Led
}
