#ESP8266 ARDUINO PWM UPDATE#

The web server with the ESP8266 NodeMCU board that displays a web page with multiple sliders works internally:.

#ESP8266 ARDUINO PWM UPDATE#

When you set a new position for the slider, it updates all clients (if you have multiple web browser tabs opened (or multiple devices), they update almost simultaneously whenever there’s a change).Move the sliders to adjust the values of the potentiometers connected to the NodeMCU board.

In each card, another paragraph displays the current LED brightness.There’s a range slider in each card that you can move to set the brightness of the corresponding LED.Each card has a paragraph to display the card title ( Fader 1, Fader 2, Fader 3).If the multiple client connected with server at a time, the PWM values of slider will updated to every client simultaneously on change. You should see the webpage with multiple sliders.Test the Project: Open a web browser on a device connected to the same WiFi network as the NodeMCU board and enter the IP address of the NodeMCU board.Upload the Code: Upload the code to the NodeMCU board using the Arduino IDE.You can use HTML, CSS, and JavaScript to create the webpage. Create a web server using the ESP8266 NodeMCU board that will display multiple sliders on a webpage.We will connect three LEDs with ESP8266 board which act as an server for controlling the brightness Using PWM signal.The following point describe the web page we’ll build for this project: The server will update all the connected clients (smartphones, tablets, computers, laptops, etc.) instantaneously when the state of the onboard LED will change Therefore, in this guide, our objective is to show you the responsiveness of a web server created with WebSocket.

It offers extremely fast response rate by using two-way communication between the client-server as compared to the simple HTTP protocol.
