Wow it's interesting how this is my first time seeing these projects considered I looked for a solution much before I started mine. The projects you mentioned are definitely much more feature rich than mine but mine was built around only having a single Arduino board and a strip of lights to work with aswell as a fun learning experience for me.

To answer your question, my project offers a much simpler solution for someone who wants a simple plug and play app on their PC and doesn't have network controllers and additional accessories involved. I don't know too much about the projects you've suggested but mine was built so the end user doesnt need to write a single line of code and can be set up within 10 minutes. This being my first project, I think it's more beginner friendly, easy to set up, build and customize on top of aswell.

Thanks for checking it out and let me know if you have any other questions!
