This was a full-stack application with a built-in music player, the output of which controlled the colour of a couple of RGB LED strips through a Raspberry Pi and some MOSFETs.

It was my first non-trivial project that got finished. Obviously, it was rather far from perfect, but I am still proud that I was able to build it on my own.

The backend logic was written in Python, and the FFT implementation was provided by NumPy. I also built a simple frontend for accessing the music player and changing the settings using vanilla web development technologies.
