In this project using only an Arduino with an Ethernet shield.
I’ll be controlling one LED and a servo, but you can apply this method to control a DC motors, buzzers, relays, stepper motors, etc..

Overview:

When you upload the the code provided in this tutorials. it creates a webserver in your LAN and you simply use the IP to access that webserver through your browser. After that it shows a webpage similar to that one below. When you press the button “Turn On LED” your url will change to: “http://192.168.1.178/?button1on” the arduino will read that information and It turns the LED On.

By default the IP is “192.168.1.178″. That also can be found on the Arduino code provided.
The Webpage will look like the image on the attachments.

Check this Video tutorial below ! (Includes demonstration)

Hello
I have an important question, thank you if anyone can help me.
What to do for converter stations by Ethernet (How does for example station number 1 find out that station number one is over and continue working now?)
Thankful

Hi,
Just create a DynDNS name, set it in your router, and create a NAT to your web server.
from your 4G device simply type the dyndns name.

Question 1 year ago

What if that IP is already in use on some network? Is there any method to assign a dynamic IP and then detect that IP on through android/java/js(through any other language, on another machine)?

Dear Sir
many thanks for your valuable site
is there any simple project for one led web control using meag2560+enc28c60 Ethernet module knowing that i ha succeed to run two leds using arduino uno with the same Ethernet module but regarding mega2560 i was unable to find any simple project on the web unless using an ethernet module equipped with an SD card which i don't have for now.

thanks

Super helpful, thank you!! I've always wondered how to control the MKR1000 from the web, this seems like a great way! Is it possible to put a login on Port 80 for security? Is that somewhere in my router settings?
