// Array of LED PINS. Makes it easy for our binary counter to decide which LEDS to blink.
//
int const PINS[] = {13, 12, 11, 10, 9};
int const PINS_SIZE = (sizeof(PINS)/sizeof(int));
int delayms = 0;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize digital pins as outputs.
  for(int led = 8; led < 14; led++){
    pinMode(led, OUTPUT);
  }
  //Serial.begin(9600);
}

//Blinks LEDS in binary
void blink_binary_number(int number, boolean vol=HIGH){
  for(int led = 0; led < PINS_SIZE; led++){
    if (bitRead(number, led) == 1){
      digitalWrite(PINS[led], vol); //Here we use our PINS array to decide which LED to blink. Since I wanted 13 to be bit 0, 12 bit 1, etc...
    }
  }
}

// the loop routine runs over and over again forever:
void loop() {
 for(int x = 0; x < 32; x++){
   delayms = analogRead(0) * 10;
   
   if (x == 31){
     analogWrite(8, 254);
   }
   
   blink_binary_number(x);
   delay(delayms);
      
   if (x == 31){
     analogWrite(8, 0); 
   }
   
   blink_binary_number(x, LOW);
   delay(delayms);
 }
