Hi.
If you open the Javascript console on your web browser, do you get any errors?
Is the ESP8266 board close enough to your router to get a good Wi-Fi signal for a good communication between the browser and the ESP8266 server?

Sara

Hello, I’ve been following this project with great interest, and after following all the steps, I’m getting the following message on the serial port:

Connecting to WiFi…
….192.168.1.37
LittleFS mounted successfully
WebSocket client #1 connected from 192.168.1.38
WebSocket client #1 disconnected

However, when I connect to the website, it takes a very long time to load, displays without CSS formatting, and then disconnects.

The serial port should display the following:

steps = message.substring(0, message.indexOf(“&”));

direction = message.substring(message.indexOf(“&”)+1, message.length());

Serial.print(“steps”);

Serial.println(steps);

Serial.print(“direction”);

Serial.println(direction);

notifyClients(direction);

notifyStop = true;

if (direction == “CW”) {
Serial.print(“CW”);
stepper.move(steps.toInt());

else {
Serial.print(“CCW”);
stepper.move(-steps.toInt());

but nothing is displayed.

I’ve tried many things, but I don’t know how to continue. I would appreciate any suggestions.

Thanks for the tutorial. A little tip: It is important that the coils of the motor are switched off when there is no action. That’s why I still have the function “stepper.disableOutputs();” in line 141. Regards, Miralem

Hello!!!
Can I use a NEMA 17 stepper motor instead of this motor and a WeMos D1 WiFi UNO ESP8266 instead of a NodeMCU?

Hi.
If you want to pass the parameters on the URL, use the following tutorial instead: https://randomnerdtutorials.com/stepper-motor-esp32-web-server/
We’re not selling that course anymore because some of the chapters are outdated-
We’re currently working on a similar eBook, with new content, and with updated subjects. It will be available in September or October.
So, stay tuned.
Thank you for supporting our work.
Regards,
Sara

Hi,
I want to thank you for this great tutorial. I’m totally newbie in this, but the steps in this tutorial are very clear so I can build this project successfully. I also learned how to upload files to the ESP8266, but how to delete unnecessary files already uploaded to the chip?
Regards,
Wawan

Hi, thanks very much for this tutorial.
Can you advise how the entry box for number of steps can already contain a predefined value for whenever the page is loaded?
Most the time I’m always using the same number so it would useful if it was already there.
Kind regards,
Will.
