Arduino Program

Part One - Setup

#include <FastLED.h> /// must have the FastLED library installed

#define LED_PIN 2       /// pin that the strip is connected to

#define NUM_LEDS 20     /// this number changes depending on how many leds are on each strip

CRGB leds[NUM_LEDS];

int soundSensor = 4;    /// pin that the sound sensor is connected to

int red = 0;            

int green = 0;

int blue = 0;

/// The three variables above will be used to generate a random number and create a different color everytime that the strip lightens up.

/// If you want only one color to show up, you do not need the three variables, but you will need to insert a number as an argument where the variables do show up in the void loop.

void setup() {

  // put your setup code here, to run once:

  pinMode(soundSensor, INPUT);

  FastLED.addLeds<WS2812B, LED_PIN, GRB>(leds, NUM_LEDS);

}

Part Two - Void Loop

void loop() {

  // put your main code here, to run repeatedly:

  int statusSensor = digitalRead(soundSensor);

  if (statusSensor >= 1){

    /// if you do not want the random color lights, do not write the next line

    red = random(1, 255); green = random(1, 255); blue = random(1, 255);   

   for (int i = 0; i < 19; i++){

    /// if you want only the single color, in the next line insert a number for each variable.

    /// for example, to get the color white

    /// leds[i] = CRGB(255, 255, 255); FastLED.show(); 

    leds[i] = CRGB(red, green, blue); FastLED.show();             

  }                                      

  delay(100);

  }

  else if (statusSensor <= 2)

  {

    for (int i = 0; i < 19; i++){

    leds[i] = CRGB(0, 0, 0); FastLED.show();

  }

  }
