💡Nature-Inspired LED Matrix Uses Fourier Transform for Audio Analysis
This LED art uses Fourier transforms to light up to music
TL;DR
A nature-inspired LED matrix uses Fourier transforms to analyze audio and light up in response. The project uses an STM32 blackpill board and CadQuery for 3D printing, with a second version featuring 5-fold symmetry and ESP32 control.
A nature-inspired LED matrix uses Fourier transforms to analyze audio and light up in response. The project, which uses an STM32 blackpill board and CadQuery for 3D printing, is a testament to the intersection of art and technology. The matrix's second version features 5-fold symmetry and is controlled by an ESP32 and Rust firmware, making it a unique installation at the Recurse Center. If you're into DIY electronics and want to see how Fourier transforms can be applied to audio analysis, this project is a must-watch. It uses an STM32 blackpill board with ARM DSP instructions, a digital I2S mic (INMP441), and ARM CMSIS library for audio processing.
