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);
}
}
}
