So I could not resist and bought it, fully well knowing that it might not work. It took a little bit of figuring out, but I finally got it to work. The code discussed in this article will probably work for all of them. The only thing that can be tricky is finding the right pins for the right library. The connectors however are geared towards mounting an Arduino Nano of course. Including the Arduino Nano clone the setup would be app 6. You can choose the top connectors or bottom pins breadboard while experimenting, but you could consider cutting off the bottom pins for your final product.
They all work great! Below a table, based on a Arduino UnoArduino Nano and my eBay Ethernet modulewith the needed pins for the three libraries I tested. As you can see, all of them use the standard SPI pins 10, 11, 12 and SS stands for S lave S elect, used to enable or disable the slave device the Ethernet module in this case. Hence the extra column for those who buy the same Ethernet Module, showing the pin number.
Just a heads-up that you may run into issues with this library. The developer stopped maintaining it.
This is the first library I found, which works great for basic purposes, but I quickly ran into the limitations of the build-in print function. Another problem is that after some digging I found that the development either has stopped development or has been very slow in the past year, which is too bad, because of the initial simplicity of this library. Note that you will need both libraries to make this work!
The library is also very compact, so it will save memory on your Arduino, compared to the other two libraries.
As always: I recommend getting the latest version from Github, although I have little hope that there will be a newer version in the near future. This library seems a very well respected in the Arduino community and with good reason. It seems one of the most complete implementations out there. Definitely a big plus for this library is that complex tasks like DHCP and such are easy to use, and offers easy accessible advanced features. Definitely excellent for the pro Arduino users.
Again: I recommend getting the latest and greatest version from Github. After testing the previous two libraries, I ran into UIPEthernet, at this moment my absolute favorite. You might see the example code below as more complicated, but that is mainly me to blame. This library is a fully compatible drop-in replacement for the standard Ethernet Library found in your Arduino IDE, which makes it easy to adapt existing examples for use with either the Arduino Ethernet shield for use with the ENC28J60 Ethernet shield.
I recommend getting the latest version from Github. Donations are very much appreciated, but not required.So you have a neat Arduino project going on. Wouldn't it be nice to add Internet connectivity and do it on the cheap as well? Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. In addition, you need to have a bit of electrical wire, a soldering iron and some soldering 'tin'.
Now it's time to wire up the module. Either use a connector to put on the Ethernet module header or solder straight onto the pins like I did. You will need just six wires, I used about inches length, but this is not critical as long as it's not a foot long.
The result should look similar to the picture. If you done this rigt, the LEDs on the module will light up when the Arduino is powered.
Last step is to upload Arduino code to connect to the Internet. I was expecting to see a level converter between the 5v arduino and 3v Ethernet enc28 board on the data lines. I've seen other DIY arduino Ethernet boards that use it. But yours indicates that is not necessary? Reply 2 years ago. The CS pin can be made to be 8 if you wish: ether.
Great tutorial tho. Reply 3 years ago. Since the ethernet module itself has some programmability I can see it being an invaluable tool for a network technician Maybe someone could write a snippet of code to blink the LEDs on a network switch in a user defined pattern just in case several were in use at once Picture a building with 4 jacks per cubicle, cubicles per floor, and 18 floors Yes, a consistent wiring pattern can find the patch panel, but then there is the tangle of patch cords.
Not working for me, I guess wiring is correct because it works with Ethercard library. The flashlight is blinking, but I cannot ping it. Any idea? Reply 4 years ago.The library allows an Arduino board to connect to the Internet. The board can serve as either a server accepting incoming connections or a client making outgoing ones.
The Arduino board communicates with the shield using the SPI bus. This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega.
On both boards, pin 10 is used as SS. On the Mega, the hardware SS pin, 53, is not used to select the Ethernet controller chip, but it must be kept as an output or the SPI interface won't work. The Server class creates servers which can send data to and receive data from connected clients programs running on other computers or devices. Corrections, suggestions, and new documentation should be posted to the Forum.

We will make a project using Ethernet and Arduino.
We will communicate over Ethernet for controlling the real life objects. You may also like to check how to interface esp wifi module with arduino. Traditional Ethernet supports data transfers at the rate of 10 megabits per second. As the needs evolved with time additional new Ethernet specifications have been developed by industry for Fast Ethernet and Gigabit Ethernet.
Interfacing Ethernet Shield with Arduino: How to send data to server
Fast internet has speed up to Mbps and Gigabit Ethernet has speed of Mbps. Ethernet cables are also prepared for specific standards. CAT 5 is the most popular cable which support both traditional and Fast Ethernet. Some devices without Ethernet supports can also support Ethernet connections through USB to Ethernet Adapters which are called dongles. Working of Ethernet is a stepwise process. Following are the steps involved in the working of internet.
Ethernet Shield comes with different pins, provided for connections. We place this shield on Arduino board properly and connect the Ethernet Port with the router providing the internet service. Note that The Ethernet shield is attached to pins 10, 11, 12, 13 so those cannot be used as general purpose input output pins. Note: In program use the ip address of your connection and if your default port is blocked by internet service provider i.#74 Web Enable your Arduino (ENC28J60 or W5100 Ethernet Controller)
Most of the times 80 works fine. After uploading program copy ip address from Arduino serial monitor and paste it in browser. You will see a html page which give you provision of controlling LED. Notify me of follow-up comments by email. Notify me of new posts by email.

The Arduino Ethernet shield connects your Arduino to the internet in a simple way. A relay is an electrically operated switch. It means that it can be turned on or off, letting the current going through or not.
The relay module is the one in the figure below. Read this tutorial to learn more about using a relay module with the Arduino board. You can use the preceding links or go directly to MakerAdvisor. View raw code. Many thanks for putting this together. Hopefully the code adapts without too much trouble.
Hello, Mr Santos I very much like your tutorials. Do you have a paperback book that includes registers,timers,direct port addressing for Arduino Uno, Nano atmel Any hint? I do understand it is thoroughly an Ethernet library issue, but please see if you can help. Yes; it does work and it did work.
Arduino Ethernet Web Server with Relay
Just for clarification so that other readers are helped; I used a cross cable between by Laptop and Arduino Ethernet Shield. I had a Dlink wifi router and possibly it does not work as switch. Yes, this project should work with a 8 board relay. You simply have to declare more outputs and add more buttons to the HTML web page. Hi Rui, Thank you for this awesome tutorial. I have a question, can I control the relay just by putting its state in the browser.
Yes, you can do that. Any thoughts? Great job! Hi Chris. Thank you for following your work. I think this question describes what you want to do: forum. I tried exact code with just change in IP address. But Server does not connect.A separate power-over-Ethernet PoE module can be soldered to the board to provide power from a conventional twisted pair Category 5 Ethernet cable.

It supports up to four simultaneous socket connections. The ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top. Arduino Ethernet Shield is open-source hardware! You can build your own board using the following files:.
There is an onboard micro-SD card slot, which can be used to store files for serving over the network. When working with this library, SS is on Pin 4. The original revision of the shield contained a full-size SD card slot; this is not supported. The shield also includes a reset controller, to ensure that the W Ethernet module is properly reset on power-up.
Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up. The current shield has a Power over Ethernet PoE module designed to extract power from a conventional twisted pair Category 5 Ethernet cable:.
NB: the Power over Ethernet module is proprietary hardware not made by Arduino, it is a third party accessory. This is on digital pins 10, 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used to select the W and pin 4 for the SD card. If you are using both peripherals in your program, this should be taken care of by the corresponding libraries. If you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it.
To do this with the SD card, set pin 4 as an output and write a high to it. For the W, set digital pin 10 as a high output. LINK: indicates the presence of a network link and flashes when the shield transmits or receives data. The solder jumper marked "INT" can be connected to allow the Arduino board to receive interrupt-driven notification of events from the W, but this is not supported by the Ethernet library.
