### 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 pushbuttonint pin= 4;          // declares LEDsint pin1= 6;int pin2= 8;int pin3= 10;int pin4= 12;int wait= 100;      // this will be used for delaysint score = 0;      // this will tell you how many times you got itint wrong = 0;      // if your wrong too many times the game starts overvoid 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);        }      }}
