• 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.

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!

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.

Just change the String(analogRead(A0)) to a pin input for status of your garage door limit switch. Function below is the response of the ESP8266 as server to the client. String prepareHtmlPage() { String htmlPage = String("HTTP/1.1 200 OK ") + "Content-Type: text/html " + "Connection: close " + // the connection will be closed after completion of the response "Refresh: 5 " + // refresh the page automatically every 5 sec " " + "" + "" + "Analog input: " + String(analogRead(A0)) + "" + " "; return htmlPage; }

@CyberCookieMonster 6 років тому

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!

@datasith 4 роки тому

Sorry I missed this comment, UKposts 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 (ukposts.info/have/v-deo/in-WiGOesI-Lx6s.html). 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!

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 7 років тому

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.

@datasith 7 років тому

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 7 років тому

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 7 років тому

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!

@MikkoPihlajamaki 7 років тому

Excellent tutorial! Just one question; Is there a specific reason why you use external editor with Arduino IDE?

@petermatthiesen8288 7 років тому

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

@datasith 7 років тому

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!

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 7 років тому

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!

@s3bk504 7 років тому

Hey, excellent video, thank you for that! My question: how can I change the format of the value I send. For example you use "text/plain" to send "Hello World", what do I have to use for sending an float type variable? Thanks ;)

@datasith 7 років тому

Hi Sebastian, thanks for watching! The "text/plain" is a directive for the client to know what type of data is being sent, the options don't specify whether it's a number or a string. This logic is implemented on the client side, that is when you read the data being sent by the server you can typically specify whether it's a string, number, json object, etc. If you wanted to specify from the server side what type of data it is, you can send it as a json object with two fields: {"value": 2.03, "type": "float"}

@aar_ash 6 років тому

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

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!
