LED Chaser

The LED Chaser project creates a dynamic LED sequence using an Arduino Mega. LEDs are turned on and off in a sequence, simulating a chaser or "Knight Rider" effect. This project is excellent for learning about controlling multiple LEDs with Arduino and can be extended for various visual effects.

Components Needed

• Arduino Mega
• 8 LEDs
• 8 Resistors (220Ω recommended)
• Jumper Wires
• Breadboard
• Power Supply

Block Diagram

Circuit Setup

Connect the LEDs to Arduino Mega:

Example connections:

LED 1: Anode to pin 2, Cathode to GND

LED 2: Anode to pin 3, Cathode to GND

Continue similarly for all 8 LEDs.

Instructions

Circuit Setup:

Assemble the circuit on the breadboard as described.

Ensure each LED is connected to the respective Arduino pin through a resistor to limit current.

Code Upload:

Copy and paste the provided code into a new sketch in the Arduino IDE.

Upload the code to the Arduino Mega.

Testing:

Upload the code to the Arduino Mega.

Observe the LEDs turn on and off in sequence, creating a chaser effect.
