Arduino Webserver Control Lights, Relays, Servos, Etc...





Introduction: Arduino Webserver Control Lights, Relays, Servos, Etc...

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..


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: “” the arduino will read that information and It turns the LED On.

By default the IP is “″. 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)

Step 1: Parts Required

  • 1x Arduino Uno
  • 1x Ethernet Shield (with Wiznet W5100 chip)
  • 1x 220 Ohm Resistor
  • 1x LED
  • 1x Micro Servo Motor
  • 1x Breadboard
  • Jumper Cables

Step 2: Schematics

Simply follow the schematics.

Step 3: Upload This Arduino Code Below:

Step 4: Final Step

It's done! If you didn't watch the youtube video yet, make sure you watch now. Not only to see the video demonstration, but you can also find more information that might help you finish this Instructable.

Now you can create your own webserver! 
And control any electronic device you desire.

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.


hello sir
i connected to nudemcu and control it with routor network
but i want control it with 4g...
how i can do it?
thank you for nice code and nice guide:)

Great job, I just wondering once Arduino programed, is USB connection still needed or it can be controlled just by network cable over web?, thanks

Why It's not working???

i didn't work. I m using an ethernet module is it the same as ethernet shield?

Yeah, I made it.

Is it possible to add the LED light status on the website?

Many thanks!

can u send me this project code to my mail

What the program does not need this project? The program will please anyone.

hey, very nice project !

can i do this with ENC28J60?

its basically has the same eternet function but i dont know which line code i should change to make this works, thanks in advance
