Arduino Music Reactive LED Strip

In this article, you will learn how to make an Arduino Music Reactive LED Strip. It is very much similar to VU Meter, but it is made with an LED strip. It will give an awesome effect of music in dark.

//Music Reactive Led Strip
int soundSensor = 12;  //define Sound Sensor Pin
int LED = 11;          //define LED Strip Pin

void setup() 
{
  pinMode (soundSensor, INPUT); //define Sound Sensor as input
  pinMode (LED, OUTPUT);        //define LED Strip as output
}

void loop()
{
  int statusSensor = digitalRead (soundSensor);   //define variable of the Sound Sensor status
                                                  //and read value of the Sensor's
  
  if (statusSensor == 1)        //When the Sensor detects a signal
  {
    digitalWrite(LED, HIGH);    //LED Strip will be active
  }
  
  else                          //If no signal is detected
  {
    digitalWrite(LED, LOW);     //The status of the LED strip is deactivated
  }
  
}
