Ethernet is the leading wired standard for networking as it enables to connect a very large number of computers, microcontrollers and other computer-based equipment to one another. In this project we are going to learn how to control any device like an LED, a relay, a light bulb, a motor and so on connected to a PIC Microcontroller from a remote location using just a web browser. An operator can use a computer, tablet or even a cellphone to control a device at a remote location. With the help of a router connected to the internet, this device can be controlled anywhere from the world in real time. Connecting to a Microcontroller using a web browser is the easiest and reliable method of establishing connectivity and above all there is no need to develop a special Graphical User Interface software on the PC or cellphone for that matter as all PCs' operating systems already have a built-in web browser or one can download one of the free other web browsers like Google chrome or Mozilla firefox for example.
WWW or the World Wide Web is a system used to find and access different resources on the internet. There are millions of websites on the internet. To access these websites, you start with "www" followed by the website domain name. These websites uses hypertext to cross-reference or link related resources anywhere on the Internet. HTML (Hypertext Markup Language) is the language used to code web pages. These pages can contain text or multimedia contents. HTML files are ASCII text files that contain the text to be displayed and the markup tags that tell how to display them. These markup tags allow the content of the page to be formatted, to insert multimedia contents etc. In this article we are going to learn the basics of creating a website from scratch using Notepad.
A graphical user interface (GUI) is one of the ways to interface between your microcontroller and a personal computer (PC) operated by a human with a mouse or a keyboard. It is always easy and require less skills to operate a device from a visual representations of the workspace (GUI) by simply clicking a mouse or using a keyboard rather than a command line. GUI can also be used to interface with other external devices located in different places. There are a lot of kinds software which can be use to design a GUI platform, the choice will usually depend on personnel preferences, software capabilities and the operating systems (Windows, Linux, Mac...). Among the popular ones we have Microsoft Visual Basic, Microsoft C#, Labview, Matlab etc.
