Story

We are from Malden high school and this is are second time coming to Metro hacks. We have always been doing software for a long and this year we wanted to try out the hardware side. we did not get a win last time but we hope to get one this year we are new skills.

Code

// Initialize LEDS and Sound and button
int ledPins[] = {7,6,5,4};
const int soundPin = 0;
const int buttonPin = 3;

int sound;
int scale;
int num_limit = 0;

//Setup 
void setup()
{
  Serial.begin(9600);
  int index;

  for(index = 0; index <= 3; index++)
  {
    pinMode(ledPins[index],OUTPUT);
  }
  pinMode(buttonPin, INPUT);
}
// Constantly looping 
void loop()
{
 int buttonState;
 buttonState = digitalRead(buttonPin);
 // When the button pressed then print out "button PRESSED"
 if (buttonState == LOW) {
    Serial.println("button PRESSED"); 
    delay(200);
 }

 // Main program
 sound = analogRead(soundPin);
 int flag = 0;
 
 if (sound < 30) {
    flag = 0;
    digitalWrite(ledPins[0], HIGH);
    digitalWrite(ledPins[1], LOW);
