IoTLED

The aim of this Project is to create, setup and program an Internet of Things device capable of controlling adressable LED-Strips. This is achieved over an ESP32-driven webapp, in which users can select between different lighting setups and also a Music-Visualizer mode using an AUX input.

The webapp used to control the LEDs is made with Flutter/Dart, which makes the app very user-friendly.

In my particular setup i use 2x WS2813 LED-strips, although it should work with any amount or any FastLED supported chipset, given some tweaking.

Built with

• arduino-esp32 - Arduino Core for ESP32
• ESPAsyncWebServer - Asynchronous Webserver Library with Websocket integration
• FastLED - Library for controlling LEDs
• SparkFun Spectrum Shield - Arduino Shield with MSGEQ7 Audio Band ICs
• Flutter - Google's Toolkit for building natively compiled applications for mobile, web, and desktop from a single codebase
• iro.js color picker - An HSV color picker widget for JavaScript, with a modern SVG-based user interface

Goals

• Getting LEDs to work with basic hardware setup
• Setup webserver
• Configure webserver to control LEDs
• Get users to transfer data with the controller
• 1st webapp/webserver-backend iteration
• Design basic webapp frontend
• Learn how to use Flutter and rewrite the entire webapp from scratch because fuck you thats why
• Integrate music visualizer
• Finalize webapp-design and LED effects
• Finalize Hardware setup, draw Circuit Diagram for installation of the Strips
• Integrate Google Assistant (?)
