[Arduino Blink] Nile Dwyer





 

Code:

int button = 13;


int redLED = 12;

int yellowLED = 11;

int greenLED = 10;


int redPedLED = 9; //Ped = pedestrian

int greenPedLED = 8;


int buttonDelay = 1000; //Delay between pushing the button and light changing

int lightDelay = 800; //Delay between switches

int stopTime = 3000; //How long the stop light stays red


void setup() {

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

pinMode(button, INPUT);


for (int i = 12; i > 7; i--){

pinMode(i, OUTPUT); //setting up board ports 8-12

}

}


void loop() {

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

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

//Starting Position

digitalWrite(greenLED, HIGH);

digitalWrite(redPedLED, HIGH);


//When button is pushed

if (digitalRead(button)==LOW){

//Transition from green traffic light to green pedestrian light

delay(buttonDelay);

digitalWrite(greenLED, LOW);

digitalWrite(yellowLED, HIGH);

delay(lightDelay);

digitalWrite(yellowLED, LOW);

digitalWrite(redPedLED, LOW);

digitalWrite(redLED, HIGH);

digitalWrite(greenPedLED, HIGH);

delay(stopTime);

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

blinker(greenPedLED, 500, 3);

digitalWrite(greenPedLED, LOW);

digitalWrite(redLED, LOW);

digitalWrite(redPedLED, HIGH);

digitalWrite(greenLED, HIGH);

}

}

//Function for blinking since i didn't feel like writing it a bunch

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

void blinker(int led, int interval, int blinks) {

for (int i = 0; i < blinks; i++){

digitalWrite(led, LOW);

delay(interval);

digitalWrite(led, HIGH);

delay(interval);

}

}
