External LED Using with Arduino Mega

The External LED project demonstrates how to control an External LED connected to an Arduino Mega. LEDs are fundamental components in electronics and are widely used for visual indications. This project utilizes the Arduino to turn the External LED on and off at specified intervals, showcasing basic digital output control.

Hardware Requirements

• Arduino Mega
• LED (any color)
• Resistor (appropriate value for the LED, typically 220 ohms)
• Jumper Wires
• Breadboard
• Power Supply

Block Diagram

Circuit Setup

Connect the External LED to Arduino Mega:

Instructions

Circuit Setup:

Wire the External LED and resistor as per the connection diagram provided.

Ensure the resistor limits the current to the External LED to prevent damage.

Code Upload:

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Testing:

Upload the code to the Arduino Mega.

The External LED should turn on for 1 second and then turn off, repeating this cycle indefinitely.
