This is a quick arduino project that is great for beginners. Enjoy! There is a video on the last step!

Step 1: What You Need

To build this project you will need:

10 LEDs, any color will do.

Some wire, I used a ribbon cable I had

Most importantly, an Arduino

Perhaps some electrical tape

Prototyping board

Step 2: Build It!

Start off by arranging your LEDs on the proto board however you choose, I chose to place them in an oval shape.

After that, solder them to the board. After they are soldered, solder all the cathodes (shorter leads, - or the lead that has the flat side) together. Then, solder a wire to each anode (other lead of the LEDs) to a wire.

Step 3: Connect It to the Arduino and Program It!

Wire it up like schematic shows!

After you are done wiring it, you can start programming the arduino. I understand that there are many ways of bumming the code but since this example is for beginners, I made it as simple and understandable as possible.

void setup() {
pinMode(1,OUTPUT);
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
pinMode(5,OUTPUT);
pinMode(6,OUTPUT);
pinMode(7,OUTPUT);
pinMode(8,OUTPUT);
pinMode(9,OUTPUT);
pinMode(10,OUTPUT);
}
void loop() {
digitalWrite(1,HIGH);
delay(100);
digitalWrite(1,LOW);
digitalWrite(2,HIGH);
delay(100);
digitalWrite(2,LOW);
digitalWrite(3,HIGH);
delay(100);
digitalWrite(3,LOW);
digitalWrite(4,HIGH);
delay(100);
digitalWrite(4,LOW);
digitalWrite(5,HIGH);
delay(100);
digitalWrite(5,LOW);
digitalWrite(6,HIGH);
delay(100);
digitalWrite(6,LOW);
digitalWrite(7,HIGH);
delay(100);
digitalWrite(7,LOW);
digitalWrite(8,HIGH);
delay(100);
digitalWrite(8,LOW);
digitalWrite(9,HIGH);
delay(100);
digitalWrite(9,LOW);
digitalWrite(10,HIGH);
delay(100);
digitalWrite(10,LOW);
}

Step 4: You Are Done!

power up your duino' and watch the lights!
