Ethernet Switching - With Arduino
Intro: Ethernet Switching - With Arduino
Aim:
Switch relays from the ethernet or the internet, using your mobile, tablet or computer with a nice graphical user interface.
Update V4.06
Please read the below steps to Step 2 if you are viewing this article for the first time.
Please go to step 3 for the latest revision which is V4.06
A user modified version with logon option is placed in step 5 for easy download.
Material:
* Arduino MEGA 2560
* Arduino Ethernet Shield
* Relay board
* RJ45 cable
Tools:
* Arduino Software version 1.0.1 (downloadable from Arduino Website )
* A / B USB cable
Infrastructure:
* Internet access with fixed IP for Arduino
* Access to your router to share the port for internet access
* Testing devices - your pc, mobile etc
Disclaimer:
* This project was tested with iPhone 3GS, iPad 2 and MacBook Pro running Safari and PC running Safari, Firefox, Opera and IE.
* This project was created on October 2012 with the mentioned material.
* Binary sketch size: 22,322 bytes (of a 258,048 byte maximum).
* This sketch does not offer any sort of authentification, therefore if required to be used from outside the network or from the internet, I suggest to configure your network to connect trough VPN. Nowadays many routers and smartphones support VPN.

STEP 1: Ethernet Switching - With Arduino - Description
Description:
* With this project, I had not included any images, or links to images from the internet. It only make use of CSS3 and HTML5.
* The simulated LEDs are created from CSS3 code.
* Some browsers does not make full use of CSS3 and HTML5. Thus I suggest using Safari.

STEP 2: Ethernet Switching - With Arduino - Program
//Ethernet Switch
//
//Intro:
//This will swich on and off outputs trough your mobile device.
//No images or links to images. CSS3 and HTML5 use.
//Though it work with other web browser, we suggest Safari for best experiance.

STEP 3: Ethernet Switching Version 4.06
Update V4.06
The Ethernet Switching has been revised and updated to include some more features.
This release is Version 4.06
There has been interest from all over the world (Brazil, Croatia, US, UK), some contacting me on these pages and some privately. Many had suggestions, on how can I improve and add some more features, in which, some of them I did.
I would like to thank everyone for the comments and the reviews this article got.
I welcome anyone for comments and suggestions for future features and options.
Below are the features I had added.
Features
1. To invert the outputs. - Done on V3.06
2. A possibility to rename the buttons - Done on V4.06
3. To be password protected. - Not yet done
4. Refresh page settable. - Done on V3.06
5 Switch On or Off the outputs on startup - Done on V3.06
6. Enable/Disable the All on/off buttons - Done on V4.01
7. Read Temperature - Done on V4.03
8. Save/Load statuses from eeprom to keep latest status after powercut - Done on V4.06
9. Option to choose which output to retain the value after power cut. - Done on V4.06

STEP 4: Images of the Hardware From Others
Here are some images of the arduino hardware from instructable user sokre666 from Croatia.
Many thanks to this user for the images and the suggestions he had made.
Many thanks to this user for the images and the suggestions he had made.
STEP 5: Other Versions by Users
User drewpalmer04 has updated the latest Ethernet Switching program and added some temperature
sensors as well the user logon option.
To compile you need to download some libraries.

1.A question.
What happens if I want to control my PC?
I need you to press, the relay activates for two seconds and then goes off. The same when I want to turn off the PC ... to enable the relay two seconds off.
Can you think of something?

I'm a beginner in arduino.......I was able to install the code for arduino uno.....
My question: How should the line / lines be written...to control (reset) a router for 10-20 seconds ...
Thank you very much for your help
DucN33 6 years ago
Do any one know why we are limit at 10 outputs ?
how do I add more output ? can not add "case 10" to the code ???
Please help
dgdimickimick 6 years ago
it is hardware limited, the Ethernet shield is using 4 pins. You could add a multiplexing chip into the mix and get upto 64 outputs.

How connect thermistor??
// Connecting a 10K3 Thermistor to the Arduino Input
// +5V �—————————[10Kohms]—————————[Thermistor]——� 0V
// To Arduino IP �———————————|
I do not understand this scheme :(

Hope that in the meantime you had found how to connect. . The lines above got a bit messed up with the text wrapping and formatting. Here is a link of what I meant.

I used without thermistor. Today I will try.
