In reply to Sara Santos. Hi Sara. I have a VPN, but I was trying to connect via the service provider modem. The issue may be a caching issue. I will look into that. Thanks.

I’m sorry but I didn’t understand. Are you using a VPN?
I don’t think you can use VPN to access the ESP web server.
Disable the VPN an try again.

Sara

Hi Sara. Sorry that I miss-spelt your name earlier. I have used Chrome, DuckDuckGo, Edge and Firefox for exactly the same result of Express VPN looking to get me connected.

Hi Sarah/Rui. Once again, great work, thanks. I have loaded this programme into an ESP-32S and all is well when I connect something other than an Android device. I was just wondering if you had received any feedback from anyone else along similar lines? I believe that my Samsung underwent a software upgrade the other day and I am sure that I tried this previously and it worked. Thanks again, Colin.

Hello
I want to follow this tutorial but power a 12v led strip. Would I damage the ESP32 board if I connect the Vin input in with the 12v power supply that came with the led strip? Would I need a step down voltage suppliers?
Thanks
I’m enjoying the tutorial on this site so far.

Hi.
You can use any of the libraries.
For a slider using the AsyncWebSever, you can take a look at this tutorial: https://randomnerdtutorials.com/esp32-web-server-slider-pwm/

If you prefer to use the other library, the following tutorial can be a good starting point: https://randomnerdtutorials.com/esp32-servo-motor-web-server-arduino-ide/

We have several web server examples with multiple different elements. You can check all our web sever tutorials here: https://randomnerdtutorials.com/?s=web+server

Sara

Hi, in this tutorial, https://randomnerdtutorials.com/esp32-esp8266-rgb-led-strip-web-server/, you use:
#include

In the web server tutorial, https://randomnerdtutorials.com/esp8266-web-server/, and the slider tutorial, https://randomnerdtutorials.com/esp8266-nodemcu-web-server-slider-pwm/, you use
#include

What’s the difference between these wifi libraries and why choose one over the other?

The slider tutorial, also uses async libraries:
#include
#include

Are there any examples with multiple elements, a slider, input buttons, input text box, all on one page? Would they necessarily have to have the async libraries if they include a slider?

Thanks!

Thank you for the wonderful tutorial!! Absolutely fascinating.

I’m super new to the world of ardiuno but was wondering what additions to the url/code to add an ability to simple turn a specific LED on or off?

Use case is a shelf to light up for a specific LED placed at a particular position – one at at time.

EX. on a 15 LED strip, to turn on or off LED # 4 to Red, or LED #6 to Green, etc.
