The LED controller project leverages Web Serial to allow users to control LEDs directly from a web browser. This setup provides an intuitive and interactive way to manage LED states via a user-friendly web interface. By setting up a webpage with controls for the LEDs, the Web Serial API facilitates communication between the web application and the IndusBoard via a USB connection.

Here’s how it works:

1. Web Page Interface: A webpage is created with a user interface that includes controls like buttons, sliders, or color pickers for the LEDs.
2. Web Serial API Communication: When a user interacts with the controls on the webpage, the Web Serial API sends serial commands from the browser to the IndusBoard.
3. IndusBoard and Arduino Sketch: The IndusBoard, running an Arduino sketch, receives these serial commands. The sketch interprets the commands and adjusts the LED states accordingly, such as turning LEDs on or off, changing their brightness, or altering their color.

This approach creates a seamless and responsive way to control LED hardware directly from a web application, making it highly suitable for a variety of projects requiring remote or user-friendly control interfaces.

Applications of LED Controllers Using Web Serial:

1. Remote Home Lighting Control:

• Use a web browser to remotely manage and control home lighting systems, enabling users to adjust lights from anywhere with internet access.

1. Dynamic LED Displays for Art Projects:

• Create real-time, dynamic visual effects in art installations by managing and changing LED displays through a web interface. Artists can easily alter lighting patterns, colors, and intensities to suit their creative needs.

1. Prototyping and Testing LED Projects:

• Quickly prototype and test LED-based projects using an easy-to-use web interface, allowing for rapid iteration and adjustment without needing to reprogram the hardware each time.

1. DIY Electronics Projects:

• Enhance DIY electronics projects by adding web-controlled lighting features, making them more interactive and accessible. Hobbyists can control and experiment with LED setups from any device with a web browser, adding a modern twist to traditional electronics projects.

This LED controller setup not only simplifies the process of managing LEDs but also opens up new possibilities for interactive and remote-controlled projects, blending web technologies with physical hardware.
