// put your setup code here, to run once:

}

}

// put your main code here, to run repeatedly:

// digitalRead(button) == LOW is pushed somehow..

//Starting Position

digitalWrite(greenLED, HIGH);

digitalWrite(stoppLED, HIGH);

//When button is pushed

if (digitalRead(button)==LOW){

//Transition from green traffic light to green pedestrian light

digitalWrite(yellowLED, HIGH);

delay(lightDelay);

digitalWrite(yellowLED, LOW);

digitalWrite(stoppLED, LOW);

digitalWrite(redLED, HIGH);

digitalWrite(goLED, HIGH);

delay(stopTime);

//Transition back to green traffic light and red pedestrian light

//Function for blinking since i didnt feel like writing it a bunch

//of times and now you can customize the blink i guess
