Sparkled

Under active development

Sparkled is in a pre-alpha state. You are more than welcome to experiment with Sparkled, but it's not yet ready for production use.

Sparkled is a web-based LED sequencer that aims to reduce the barrier to entry for lighting projects.

Features

With Sparkled, you get an integrated solution containing:

• A rich web interface for staging, sequencing, previewing and scheduling music-backed LED animations
• A fast UDP service to stream rendered pixel data to Sparkled clients, which use the data to drive LED strips (or whatever you want!)

Clients

Sparkled clients are responsible for rendered pixel data from the Sparkled server and displaying it on the LED strips. The official Sparkled clients are listed below:

• sparkled-client-esp (ESP32 and ESP8266)

Roadmap

• Add more effect types
• Multithreaded rendering
• Support sequences without music (currently requires a mute MP3 file to be uploaded)
• Ability to replace MP3 files for existing sequences (even with different lengths)

Getting Started

Sparkled is currently in pre-alpha, so significant chunks of core functionality are still missing or incomplete.

These instructions will get you a copy of the project up and running on your local machine.

Prerequisites

The following software and hardware requirements must be met before installing the Sparkled server:

• Java 11 or later
• Gradle 7 or later (or use gradlew)
• A modern web browser

Installing

Fork and clone the repository

SSH:
git clone [email protected]:<your_username>/sparkled.git

HTTPS:
git clone https://github.com/<your_username>/sparkled.git

##Build the project

Note: the initial build will take quite a while, as the dependencies need to be downloaded.

cd sparkled
./gradlew clean buildWebUi copyWebUi build

Run Sparkled

cd build/libs
java -jar sparkled-all.jar

Wait for the application to start, then connect to the UI in Chrome via the following URL:

http://localhost

Running the tests

Use gradle to run the backend unit tests:

cd sparkled
./gradlew test

Use npm to run the frontend unit tests:

cd sparkled/webui
npm run test
