In previous articles, we connected the ESP8266 to a pre-existing WIFI network. It is the commonly used method in projects, especially when there is interest in internet access.
For these cases, the ESP8266 operates as a “station” on the network. But we can find scenarios where there is no WIFI network to connect. Can we still use the ESP8266 in these cases? Yes, we can!
ESP8266 Operational Modes
The ESP8266 WiFi module can operate in 2 different modes:
STA (the module operates as a station and is available to connect to an Access Point).
AP (the module creates a network with customizable SSID and Password. We will discuss how each mode works, its limitations, and how to use
STA Mode
We use the STA mode to connect the ESP8266 to a pre-exist ...

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create Web Server with ESP8266 using SPIFFS.
We've already seen how to create a web server and how to provide an HTML page on our ESP8266. We use the PROGMEM command to store an HTML code in FLASH memory. For a simple page, this works fine, but what if we have a more complex webpage? With a better style? What if we want to include images?
Today we will learn how to use SPIFFS with ESP8266 to store files (regardless of type) in FLASH memory.
What is SPIFFS?
SPIFFS (SPI Flash File System) is a system designed for managing SPI flash memory in embedded devices. Its main goal is to use minimal RAM to access files. It's very useful when using pen drives ...
Hello friends, I hope you all are doing great. Today, we will create a web server with ESP8266 microcontroller to control the activation of an LED. The goal is to understand how the ESP8266 connects to a WiFi network, how it sets up a web server, and how it is possible to exchange information between the browser and the esp8266.
Components Required
1x Computer/notebook with Arduino
1x Mini-USB cable.
1x NodeMCU (ESP8266 Breakout Board)
Internet Browser (Chrome, Firefox, IE…)
ESP8266 Libraries for Arduino IDE
For this project, we will use two libraries:
ESP8266WiFi: This library carries all the functions necessary for the ESP8266 to connect to a wifi network.
ESPAsyncWebServer: This library carries the functions needed to create an ...
Designing homes and landscapes is a dream job for many individuals, but the challenges of becoming a licensed architect often stand in the way of this dream.

If you’re hosting a website, eCommerce business, or even just the latest online game with your friends, you know that performance, reliability, and security matter. To take your web hosting to the next level, consider what a dedicated server could do for you. With full access to your own web server, you’ll have more control and better performance from your hosting service. What’s not to love about that?
But how do you know when you really need a dedicated server? Many smaller websites can perform just fine without one, but for larger sites and businesses, the benefits quickly become apparent. Here, we’re taking a closer look at dedicated servers and what they can offer for your online experience. We provide some key information about dedicated ser ...
