In this tutorial, we will learn how to display images (format .png or .jpg) in ESP32 and ESP8266 web servers using Arduino IDE. For demonstration, we will build a web server with a simple HTTP protocol as well as an asynchronous library. We will see three different ways to embed images into a web page … Read more
In this tutorial, we will create an ESP8266 NodeMCU web server by using a WebSocket communication protocol and Arduino IDE that will control the onboard LED of ESP8266 NodeMCU. Through WebSocket communication protocol, several clients can be connected to the server concurrently without blocking each other. We will see that unlike HTTP, a websocket server … Read more
In this tutorial, we will learn to create a web server with ESP8266 NodeMCU using LittleFS and Arduino IDE. Firstly, we will learn how to store CSS and HTML files in the LittleFS flash file system of ESP8266 and build a web server through those files. Instead of hard coding the HTML as string literals … Read more
In this tutorial, we will show you how to install a file system uploader plugin in Arduino IDE to upload files to ESP8266 NodeMCU flash (LittleFS). By default, there is no support in Arduino IDE to upload files to ESP8266 flash filesystem. But we can install a plugin to add a file uploading feature in … Read more
