Circular Led Light Chaser using Arduino

This a Project for Arduino beginners,The led’s formed as circle glows one by one with some time delay will be interesting to see in action.

circular led chaser arduino

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

Connect the Leds with arduino as shown in below figure.Connect all cathode(short pin) and connect it with ground and Each anode(other pin) to arduino digital output pin as shown i figure.instead of breadboard you can solder it in PCB in circular or oval arrangement.

Breadboard view

Start your Arduino Programmer and enter the below program

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);
}

That is now give power to your arduino board and watch your masterpiece.
