This will get you a very nice set of flashing LEDs just connect the LEDs (I used a breadboard) and turn it on. 

Step 1: Program the Arduino.

Insert the following Code:
int led1Pin=1;
int led2Pin=2;
int led3Pin=3;
int led4Pin=4;
int led5Pin=5;
int led6Pin=6;
int led7Pin=7;
int led8Pin=8;
int led9Pin=9;


voidsetup() {
  pinMode(led1Pin, OUTPUT);
  pinMode(led2Pin, OUTPUT);
  pinMode(led3Pin, OUTPUT);
  pinMode(led4Pin, OUTPUT);
  pinMode(led5Pin, OUTPUT);
  pinMode(led6Pin, OUTPUT);
  pinMode(led7Pin, OUTPUT);
  pinMode(led8Pin, OUTPUT);
  pinMode(led9Pin, OUTPUT);
}


voidloop() {
  digitalWrite(led1Pin, HIGH);
  delay(100);
  digitalWrite(led1Pin, LOW);
  digitalWrite(led2Pin, HIGH);
  delay(100);
  digitalWrite(led2Pin, LOW);
  digitalWrite(led3Pin, HIGH);
  delay(100);
  digitalWrite(led3Pin, LOW);
  digitalWrite(led4Pin, HIGH);
  delay(100);
  digitalWrite(led4Pin, LOW);
  digitalWrite(led5Pin, HIGH);
  delay(100);
  digitalWrite(led5Pin, LOW);
  digitalWrite(led6Pin, HIGH);
  delay(100);
  digitalWrite(led6Pin, LOW);
  digitalWrite(led7Pin, HIGH);
  delay(100);
  digitalWrite(led7Pin, LOW);
  digitalWrite(led8Pin, HIGH);
  delay(100);
  digitalWrite(led8Pin, LOW);
  digitalWrite(led9Pin, HIGH);
  delay(100);
  digitalWrite(led9Pin, LOW);
}


You can edit the delays for different speeds.
I don't see any video period.
Go blame google-. It's affected youtube negatively, so it should be called Google-
In the video you didnt show it working.
Really? It works. Sorry for that.
