This project demonstrates how to blink an external LED using a user-defined digital pin on an Arduino board (e.g., pin 11). It is a beginner-friendly example to understand digital output and basic hardware interfacing.
- Uses a user-defined digital pin (Pin 11)
- External LED interfacing
- Simple and easy-to-understand code
- Ideal for beginners in embedded systems
- Arduino board (Uno/Nano/etc.)
- LED
- 220Ξ© resistor
- Jumper wires
- Breadboard (optional)
