• Description:
In this video I go over the process, step-by-step, of how to write code in the Arduino IDE for getting a web server running. One of the most common tasks when using the ESP8266 is setting it up as a device that connects to a network and responds to traffic on it (i.e., a Webserver). Though several code samples exist already, I wanted to explain what you need from start to finish.

[@jose-azevedo]

After going through at least 30 tutorials on KZbin, yours was the first one that went step by step and made me understand a bit what each of these commands do, thank you very much Cisco!!

[@datasith]

Hey José. I'm so very glad it could help, thanks so much for letting me know. It keeps me motivated knowing that people find this stuff useful!

[@allersvp]

after many other KZbin videos i though i have to ready full books myself to understand .. till i got to your videos (calm and step by step) ... now i understand everything.... you are the EVER BEST ... thanks bro

[@datasith]

No worries, thank you for watching. It makes me happy you found it useful, and it helped you on your projects!

[@timecentral3134]

Very nice video!!! Works with an ESP32 (specifically, I have the ESP-WROOM-32 ESP-32s board) with the only changes being the library names. I had to change ESP8266WiFi.h to WiFi.h and ESP8266WebServer.h to WebServer.h. Thank you so much for the time you take to share this information! The audio is very crisp and clear in this, which makes following along easy. As a bonus, now that I have it working, the family is impressed and excited for it's applications (remote control custom lights / remote cat treat dispenser). Thanks once again!

[@datasith]

Thanks for the compliment, I'm glad you found the content useful! Thanks so much for sharing details about your project, it makes me happy that you got it done as well as gathered interest in your project from the fam. If you ever post projects online, let me know and I'd be happy to take a look!

Can't we directly assign the web server duty to nodemcu, without using an AP? Can't we assign an IP address by ourselves to Esp?

[@SimonSemore]

Great tutorial, thank you so much for your videos. You really explain all of the functions and jargon in the code and make it much easier to learn. I like your esp8266 OTA video very much also. In that video you referred to your next video being able to send code via OTA at any time without needing to reset. I'm struggling to figure out how to update code. For example I'd like to add new firmware to update my led controllers to change virtual pin settings etc.

[@CyberCookieMonster]

Thanks for the videos. They are very helpful. The use of 204 response code instead of 200 was very useful. The logic in your script is by far the easiest to understand. What I need now, though, is a way to have a html link or button trigger the toggleLED function instead. I want the page to offer the same functionality, but without typing into the URL or having to build a client side phone app. I only need about 10 buttons and it seems I can reuse whatever logic is needed. Thanks!

[@CyberCookieMonster]

BTW, I am your patron. :)

[@datasith]

Sorry I missed this comment, KZbin finally lets us sort by "Comments I haven't responded to" so I'm going through the list. Have you looked at the Websockets videos? It's by far the easiest way to get data back and forth from a web client and the ESP8266 (kzbin.info/www/bejne/iIDIhWCdrr6NnNk). Let me know if you can adapt the code to your needs, or otherwise I can give you a better example. Feel free to ping me on Patreon any time!

[@a14266]

Thanks for the informative video, May i know why do you have to use Terminal Vi to write the coding ? Why can't just directly type into the Arduino IDE ?

[@datasith]

Heya! Thanks so much for watching and for the kind words. It's a matter of preference. We use Vim for a lot of different tasks (e.g., when working on our remote servers) so we're very familiar with it. Other popular text editors for programmers/developers include Sublime Text. However, the Arduino IDE's built-in editor works great too! Note that as your programs become more complex, the external editors have functionality that makes life a lot easier.

[@petermatthiesen8288]

Exatcly. Why? I also would like to know . . .

[@datasith]

Hey, Mikko. Using a full-feature editor can be useful when writing longer programs, but it's only a matter of preference. I like *Vim* because all editing operations can be done using keystroke combinations, and I've been using it for a looooong time. These days, a popular one to try is *Sublime Text* if you'd like. Thanks for watching!

[@datasith]

Hey, Peter. Mostly a matter of preference and habit as you can see in the previous response. Thanks for watching!

[@datasith]

Hmm that's strange. In your computer is connected to the same Wi-Fi network, you should be able to navigate to esp8266.ip.address/ using the ip address you're seeing and the browser should display the "Hello World" message. If you try the /toggle path, then nothing occurs on the browser, but the LED should toggle on and off. Hope that helps!

[@TheKatandFriends]

Hello, I've been having some trouble getting things working on my ESP. I have a version 1 board connected to an arduino that is connected to the USB port. Is there anyway around this? Will I need to get some other form of USB connection to the ESP Module so that I can upload this to it directly? and if I do will I be able to control my arduino with the functions in the same way? The reason I'm using an arduino uno is because I have a motor shield attached and my final goal will be to control a stepper motor from a remote location. Thank you, awesome video... one of the clearest I've found on explaining the ESP Module and the Wifi library.

[@datasith]

Thanks for the kind words! The ESP-01 doesn't have a built-in USB-to-Serial chip so you'll always need either an Arduino or a dedicated board for this functionality. Alternatively you could use Over-The-Air (OTA) programming for loading your sketches to the ESP-01 without a wired connection. If instead of using an Arduino Motor Shield you switch to a standard Motor Controller breakout board you can wire it to the ESP8266 and eliminate the need for the Arduino altogether. There's nothing wrong with your current setup, but our suggestion will simplify things a bit, having to worry only about a single microcontroller!

Thank you for this very nice and clear video. When I tested the WiFi connection, on the serial monitor, i could see the dot point endlessly showing up but no IP adress appearing, could it mean a problem with the WiFi on my nodeMCU?

[@datasith]

Yup, that usually means that there was something wrong with your credentials (ssid/password). That's not the only reason, but definitely the lack of IP address indicates that the ESP8266 hasn't connected to the router yet!

[@rusty_junk]

I know I'm late to the party but why use an external editor? It looks like your just using the equivalent to a Windows command prompt window?

The Arduino IDE allows you to upload your own firmware (the code that you write). You don't need a bootloader or a pre-compiled firmware file. Check out our other videos for how to get started. Thanks for watching!

Hi, I had a small question. I have a larger code running on my ESP8266 module. I'm using a webserver to send a request to toggle an led as well. This seems to work fine when the program contains code for only this. When I integrate it into my bigger program and try to toggle the LED, it doesn't. I believe this is because I don't exactly know how handleClient method works. Can you help me out? It is kinda urgent.

[@datasith]

Can you send us the code over email, there are many possibilities and not enough information to even make an educated guess :-/ Thanks for watching though, we're glad that at least part of the code is working :)

Hey! I'm really sorry about that! I was in the middle of a project submission fiasco and probably wrote the comment in a hurry. I really appreciate their work and think that my project would not have been possible without their help. As for the 'urgent' part, it was by no means said in an authoritative way. It was a humble request to help me out at the earliest, if possible. Anyway, hope that clears things out. Thanks again for your work and great tutorials.

[@francescofabbro3543]

Hi, first of all congratulations for the videos, very complete. I have only one question... I cannot make it to install the library ESP8266Wifi...

[@datasith]

The library is automatically installed when you add support for the ESP8266 board in the Arduino IDE. Make sure you select one of the ESP8266 boards from the menu before compiling/uploading the code. When you do this, the Arduino IDE 'knows' where to find the library. Thanks for watching!
