Hello All

Need help in a small project. I have Arduino Uno R3 + Ethernet W5100 + 8 Channel Relay now I want to make a web page where I can get relay off/on or reboot botton like this

Relay 1  =   Off    On     Reboot
Relay 2 =   Off    On     Reboot
Relay 3 =   Off    On     Reboot
Relay 4 =   Off    On     Reboot
Relay 5 =   Off    On     Reboot
Relay 6 =   Off    On     Reboot
Relay 7 =   Off    On     Reboot
Relay 8 =   Off    On     Reboot

If some one press "on" relay will be switch on and "off" to switch off and "reboot"  will off  the relay for 5 second and turn it on.

I don't have any coding knowledge so please help me.

Then, why did you take on this project? If the aim is to learn, "do my work for me" is a cop-out.

There are examples in the Ethernet library that show how to display the analog values to the client. It isn't hard to see how to substitute that part of the code for code that shows a form with buttons on it. Some time at a site learning html and forms and submit buttons, etc. would be useful.

How do you reboot a relay?
The art of getting good answers lies in asking good questions.

some web page control test code that might be adapted to do what you want.

Code: [Select]

//zoomkat 8-04-12
//simple button GET server code to control arduino pins
//for use with IDE 1.0 or later
//open serial monitor to see what the arduino receives
//use ' instead of " in the html
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields

How do you reboot a relay?


I know basic of HTML, PHP but don't know arduino code. reboot mean i want to power off it for 5 second and turn it on again.

So what code have you written so far that doesn't work?

Zoomcat: can you please upload the HTML code that we can put in SD CARD and access the site.



Till now I have done following

Without SD cARD
Accessing and controlling devices through buttons and form submission.

With SD CARD
I can access and control with buttons but not with form submission.

Please help with the form submission part...  Also kindly upload both arduino and HTML code.


Thanks in advance
