just add a mosfet as switch setup instead of led, watch the video for more info

Code

Untitled file

C/C++
its a pretty basic sketch which triggers the gate of MOSFET when Arduino receive a signal from microphone module
int soundSensor = A0;
int LED = 2;

void setup()
{
  pinMode(soundSensor,INPUT);
  pinMode(LED,OUTPUT);
}
void loop()
{
  int statusSensor = digitalRead (soundSensor);

  if (statusSensor == 1)
  {
    digitalWrite(LED,HIGH);
   }
   else
   {
    digitalWrite(LED,LOW);
   }
}
