Example Code
This example toggles an LED ON/OFF when sound is detected.
const int soundPin = A2;
const int LED = 2;
void setup() {
pinMode(LED, OUTPUT);
pinMode(soundPin, INPUT);
digitalWrite(LED, LOW);
}
void loop() {
if (digitalRead(soundPin) == HIGH) {
digitalWrite(LED, !(digitalRead(LED)));
delay(100);
}
}
