A Graphical User Interface (GUI) is a type of user interface that allows users to interact with a computer system through graphical elements such as icons, menus, and buttons.

Graphical User Interfaces are an essential part of modern software applications. They provide a visual way for users to interact with the software, making it more intuitive and user-friendly.

GUI has changed how we all interact personally and professionally. It's fair to say, that without the graphical user interface, computing wouldn't be what it is today.

But a web-based graphical user interface (GUI) for administration and reporting for your microcontroller device can look very professional and be super useful.
