Building a Simple ESP32 LED Webserver: Step-by-Step TutorialWhat is an ESP32 Web Server?
In the Internet, all the websites are hosted on a computer and this computer is called a server. Since this particular server is used to serve web pages and web requests, we call it a web server. Instead of using a computer, we can also use an ESP32 to respond to web requests, thanks to the ESP32’s built-… |
