LED Chaser with Arduino Nano

The LED chaser project, also known as a "Knight Rider" effect, creates a chasing pattern with a series of LEDs. In this project, an Arduino Nano is used to control the LEDs, making them turn on and off sequentially in a chasing pattern.

Components Needed

• Arduino Nano
• 6 LEDs
• Resistors(220Ω)
• Breadboard and Jumper Wires

Circuit Diagram

Circuit Setup

1.LED Connections:

Connect each LED to digital pins 2 to 7 on the Arduino Nano.

Use 220Ω resistors to limit the current to each LED.

Instructions

1.Circuit Setup:

Connect the LEDs and resistors to the Arduino Nano as described above and shown in the circuit diagram.

2.Code Upload:

Copy and paste the provided code into the Arduino IDE.

Select the appropriate board (Arduino Nano) and port from the Tools menu.

Upload the code to the Arduino Nano.

3.Testing:

Once the code is uploaded, observe the LEDs creating a chasing pattern, where they turn on and off sequentially in both directions.

Applications

decoration: Use the LED chaser effect for decorative lighting in various projects.

signage: Implement LED chaser patterns for attention-grabbing signs or displays.

Notes

Adjust the delay value to change the speed of the chasing pattern.

Experiment with different LED configurations and patterns to create unique effects.
