Arduino Light Project

To make an Arduino Light Project, you will need:

1 Arduino board

1 breadboard

15 wires

7 220 ohm resistors

7 Light Emitting Diodes

Connect them all where the lights are side-by-side. Then, use the following code:

void setup() {
pinMode(1, OUTPUT);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
pinMode(5, OUTPUT);
pinMode(6, OUTPUT);
pinMode(7, OUTPUT);
}

void loop() {
  for (int i = 0; i < 2; i++){
    digitalWrite(1, HIGH);
    delay(50);
    digitalWrite(1, LOW);
    delay(50);
    digitalWrite(2, HIGH);
    delay(50);
    digitalWrite(2, LOW);
    delay(50);
    digitalWrite(3, HIGH);
    delay(50);
    digitalWrite(3, LOW);
    delay(50);
    digitalWrite(4, HIGH);
    delay(50);
    digitalWrite(4, LOW);
    delay(50);
    digitalWrite(5, HIGH);
    delay(50);
    digitalWrite(5, LOW);
    delay(50);
    digitalWrite(6, HIGH);
    delay(50);
    digitalWrite(6, LOW);
    delay(50);
    digitalWrite(7, HIGH);
    delay(50);
    digitalWrite(7, LOW);
    delay(50);
  }
  for (int i = 0; i < 3; i++){
    digitalWrite(1, HIGH);
    delay(50);
    digitalWrite(2, HIGH);
    delay(50);
    digitalWrite(3, HIGH);
    delay(50);
    digitalWrite(4, HIGH);
    delay(50);
    digitalWrite(5, HIGH);
    delay(50);
    digitalWrite(6, HIGH);
    delay(50);
    digitalWrite(7, HIGH);
    delay(50);
    digitalWrite(1, LOW);
    delay(50);
    digitalWrite(2, LOW);
    delay(50);
    digitalWrite(3, LOW);
    delay(50);
    digitalWrite(4, LOW);
    delay(50);
    digitalWrite(5, LOW);
    delay(50);
    digitalWrite(6, LOW);
    delay(50);
    digitalWrite(7, LOW);
    delay(50);
  }
  for (int i = 0; i < 3; i++){
    digitalWrite(1, HIGH);
    delay(50);
    digitalWrite(2, HIGH);
    delay(50);
    digitalWrite(3, HIGH);
    delay(50);
    digitalWrite(4, HIGH);
    delay(50);
    digitalWrite(5, HIGH);
    delay(50);
    digitalWrite(6, HIGH);
    delay(50);
    digitalWrite(7, HIGH);
    delay(50);
    digitalWrite(7, LOW);
    delay(50);
    digitalWrite(6, LOW);
    delay(50);
    digitalWrite(5, LOW);
    delay(50);
    digitalWrite(4, LOW);
    delay(50);
    digitalWrite(3, LOW);
    delay(50);
    digitalWrite(2, LOW);
    delay(50);
    digitalWrite(1, LOW);
    delay(50);
  }
}

This should create a lot of flashing lights.
