- An arduino
- a DC power supply
- a bread board
- 4 led's
- 9 jumper cables

Step 2: Step 1

Picture of Step 1
Plug 4 jumper cables in the input / output  ports
plug them into pins 8-11

Step 3: Step 2

Picture of Step 2
plug 4 leds into your bread board make sure that you have them all the same way
ex. all the positive leads on the right and all the negative leads on the left

tip- the shorter lead on the led is the negative lead

Step 4: Step 3

Picture of Step 3
plug one  jumper cable into ground and plug the other end of the cable into the negative rail on your breadboard

plug all the input / output pins 8-11 into the same rail as the positive leads of your leds

Step 5: Step 4

Picture of Step 4
take 4 jumper cables and plug one end into the negative rail on your bread board and the other end into the negative lead on your leds

Step 6: Step 5

you will need to copy the sketch below and paste it into your arduino software and upload it to your arduino



void setup(){
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
}
void loop(){
  digitalWrite(8, HIGH);
  delay(100);
  digitalWrite(8, LOW);
  delay(3);
  digitalWrite(9, HIGH);
  delay(100);
  digitalWrite(9, LOW);
  delay(3);
  digitalWrite(10, HIGH);
  delay(100);
  digitalWrite(10, LOW);
  delay(3);
  digitalWrite(11, HIGH);
  delay(100);
  digitalWrite(11, LOW);
  delay(3);
    digitalWrite(10, HIGH);
  delay(100);
  digitalWrite(10, LOW);
  delay(3);
    digitalWrite(9, HIGH);
  delay(100);
  digitalWrite(9, LOW);
  delay(3);
    digitalWrite(8, HIGH);
  delay(100);
  digitalWrite(8, LOW);
  delay(3);
}

Step 7: Finished

now you have a cool little light show

i'm not sure if it is formatted correctly
If you upload that to YouTube, you can embed it in your project.
