Source codes

Connect S port of electronic brick of microphone to A0 port of Arduino, and we will use the following program to read the analog value. When the value exceeds the threshold, the LED indicator will flash.

const int ledPin =  13;      // šviesos diodo prievadas
const int thresholdvalue=400; //reikšmė kurią viršijus bus įjungiamas LED
void setup() {
     pinMode(ledPin, OUTPUT);
}
void loop() {
  int sensorValue = analogRead(A0); //nuskaitomas A0 prievadas (garso reikšmė)
  if(sensorValue>thresholdvalue)   //Jei garso reikšmė viršija thresholdvalue reikšmę
  digitalWrite(ledPin,HIGH); //įjungiamas šviesos diodas
  delay(200);
  digitalWrite(ledPin,LOW);
}
