The project features an Arduino Uno housed in a frame I built out of a few K'Nex pieces. Connected to the Arduino is an HC-06 Bluetooth module and five WS2812B RGB LED panels. These panels are arranged into a cube shape around the K'Nex frame. I've then written some Arduino code to be able to interact via Bluetooth with the Android application that I've also built. Most of this project's functionality and user interaction occurs with the app and its features are:

• • Simple and intuitive UI for building or editing an effects list

  • Instant effect previewing with the built-in 3D preview (with its own set of touch controls)

  • Save and load the customized effects lists (called profiles) from system storage

  • Quick Bluetooth connectivity between application and Arduino

  • Upload a profile to the Arduino with the click of a button

  • Customizable application preferences

  • Help section with both written and video instructions on how to perform any in-app task

  • About page with list of all external libraries used to create the application

The source code can be viewed on GitHub.

An installable APK can be downloaded from GitHub Releases.

⭐ Featured on the official Processing for Android gallery.

• Android/Java for application development (supports Android 9.0+)

• Processing for application's 3D sketch

• Arduino Uno for hardware support

• Bluetooth for application/Arduino communication

Please see the project's GitHub repository README for a complete list of external libraries used.
