# Ethernet Controlled LED

> A starter project for those with Ethernet shields.

Original author: tylerpeppy (source: https://www.hackster.io/tylerpeppy/ethernet-controlled-led-4c2586)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))
- **Arduino UNO** x 1 ([docs](https://www.farnell.com/datasheets/1682209.pdf))

## Article

The project "Ethernet Controlled LED" showcases how to control an LED remotely using an Arduino board with Ethernet Shield. The Arduino board is programmed to set up a server, which waits for incoming client requests. Once a client sends a request, the server sends a response back to turn the LED on or off. The code implements the use of Ethernet library to establish a network connection and the use of RESTful API to exchange data between the client and the server. The project demonstrates a basic application of Internet of Things (IoT) and can be a starting point for further exploration in this field.
