Light Catching Game

This is a game where you want to push the button when the middle LED lights up. Just a little more advanced while loop than the last one.




int button = 2;      // declares pushbutton
int pin= 4;          // declares LEDs
int pin1= 6;
int pin2= 8;
int pin3= 10;
int pin4= 12;
int wait= 100;      // this will be used for delays
int score = 0;      // this will tell you how many times you got it
int wrong = 0;      // if your wrong too many times the game starts over

void setup ()
{
  pinMode(pin, OUTPUT);       // sets as output
  pinMode(pin1, OUTPUT);
  pinMode(pin2, OUTPUT);
  pinMode(pin3, OUTPUT);
  pinMode(pin4, OUTPUT);
  pinMode(button, INPUT);      // sets as input
  Serial.begin(9600);
}
void loop ()
{
   while (digitalRead(button) == LOW)      // when the button is low, do the following
      {
       for (int x = 4; x<=12; x=x+2)       // sets loop to cycle through lighting up LEDs
        {
         digitalWrite(x, HIGH);
         delay(wait);
         if (digitalRead(button) == HIGH)   // if the button is press
           {
             if (x == 8)                    // and the LED 8 is on
             {
              delay(1500);                  // wait 1.5 seconds
              score= score+1;               // add one to the score
              Serial.println(score);        // relay score back to computer
              wait = wait*.9;               // decrease delay between LEDs
             }
             else
             {
               digitalWrite(x, LOW);        // if button is pressed and its not the right LED
               x = 2;                       // loop starts over
               wrong= wrong+1;              // the wrong count increases
               if (wrong == 5)              // if you get 5 wrong
               {
                 for (int x = 4; x<=12; x=x+2)
                 {
                   digitalWrite(x, HIGH);    // all lights will come on
                   delay(1000);
                   wrong = 0;                // resets wrong count
                   score = 0;                // resests score
                   wait = 100;               // resets delay time
                 }
               }
             }
           }
         digitalWrite(x, LOW);
        }
     }
}
