LED- Cheaser Festival Light With Arduino

 

LED- Chaser Festival Light With Arduino

To make this project you all need some simple components. 

Component-

• Arduino UNO
• 220-ohm resistor
• LED x8
• Jumper wires
• Breadboard

1st, put all LEDs on the breadboard and set the (-) terminal common. then connect every led with pin 2 to pin 9 of the Arduino board using jumper wires.

After complete all setup lets connect the ground wire via a 220ohm resistor. according to this diagram. 

Now connect your arduino board with your computer or mobile via USB cable, and upload the following code. 

--------------------------------------------------------------------------------------------------------

Here Is the Code -

int ledPins[] = {2, 3, 4, 5, 6, 7, 8, 9};  // Pins for the LEDs

int numbers = 8;

void setup() {

  // Initialize each LED pin as output

  for (int i = 0; i < numLeds; i++) {

    pinMode(ledPins[i], OUTPUT);

  }

}

void loop() {

  // Forward sequence (left to right)

  for (int i = 0; i < numLeds; i++) {

    digitalWrite(ledPins[i], HIGH);  // Turn on the current LED

    delay(100);                      // Delay to create the running effect

    digitalWrite(ledPins[i], LOW);   // Turn off the current LED

  }

  // Backward sequence (right to left)

  for (int i = numLeds - 1; i >= 0; i--) {

    digitalWrite(ledPins[i], HIGH);  // Turn on the current LED

    delay(100);                      // Delay to create the running effect

    digitalWrite(ledPins[i], LOW);   // Turn off the current LED

  }

}

After uploading this code your project will start working.
