In this part of the tutorial the arduino and ethernet shield serves up a web page that allows an led to be switched on and off.
Arduino ethernet led on off.
It also shows how to write a simple web page in html.
Arduino ethernet remote control of led from mobile phone.
This example shows how to make an app that controls an arduino board by communicating over the tcp networking protocol.
This arduino breadboard project uses an arduino uno and arduino ethernet shield with sd card as a web server.

The purpose of this instructable to show some practical coding including how to modify a standard arduino sketch to do something extra in this case controlling a led from a mobile phone.
To begin make code for control led we must add spi and ethernet library.
To make an led can be controlled from pc we will program the arduino as a server.
The arduino server will wait for the connection from cilent.
For this project i used the arduino uno r3 and arduino ethernet shield.
I wanted to investigate controlling the digital outputs on a arduino from a webpage so i decided to build a simple setup to turn a led on and off from a webpage.
Communication with the arduino is made using a wifi shield or an ethernet shield.
Arduino webserver controlled led.
An led is switched on and off using a web page checkbox control.
When using a wifi shield you communicate directly from your mobile device to the arduino.
Arduino led on off tcp.
This video shows the led being controlled from the web page.
This is a simple routine to turn an led on or off with a single pushbutton.
Two push button switches and two leds are connected to the arduino.
The client will send commands to the arduino via port 23 of tcp port numbers.
The led is connected to one of the arduino pins this simple circuit can be built on a breadboard.
