I have worked on Arduino uno for doing basic projects. Now i have interface Arduino Uno with ESP 8266 wifi module and 16*2 LCD. Now i want to send text from webpage that is i have a text box in webpage and submit button. When i type text in text box and click submit button,the text should appear on LCD. Any idea about both Html part and arduino part .

Thank you

My Youtube video #33 deals with ESP8266 so it may cover what you're after - see the code too that has some simple html that gives you an idea of what to do. It turns an LED off and on using your browser to do this. URL in the signature of this post.

You say you have an Arduino connected to an ESP8266 - presumably acting as a server (not a client) and which is also connected to your LCD.

Your ESP8266 serves up a web page on your browser (all connected via your home wifi).

Now you want to type something into that box and display that on the Arduino's LCD.

You need to get the webserver / browser link working first (as shown in my video). Adding in extra HTML to accomplish what you want is straightforward but first steps first.

Essentially you need an a textbox (not a link that I have in my demo) that is served up on the webpage. You submit that and extract it from the data being submitted. But get the first bit working first. Or tell us that you actually have that bit working.

I have interfaced Arduino Uno with ESP8266-01 and 16*2 LCD .I want to control LCD from webpage. I am new to server,web side.Now the webpage has two text box and submit button. When i type text on webpage and click on submit button ,text should appear on LCD. I am stuck in web part . How to communicate web part and Arduino. I tried HTML with GET method . But not working .Some suggested saying try Php. Can anyone please help.

Thank you in advance.

But not working

. . . is the phrase most likely here to raise blood pressure.

So did you watch my video that shows some basic html that at least may have moved your project forward?

It shows how you can parse the incoming parameter string from the URL so you can take the correct logical action in your code. If you can get that working then the above question becomes moot as you will realise how to do it (fairly crudely, but, hey, it works!).
