From the project
This project contains a complete design for a **sound-reactive light organ** with 3 channels (bass, mid, treble), using a PCB designed in KiCad and a custom 3D-printed case modeled in FreeCAD.
The circuit detects three different frequency bands from an audio signal (low, mid, and high), and lights up a dedicated LED for each band accordingly.
- Low frequencies (bass) → LED 1 - Mid frequencies → LED 2 - High frequencies (treble) → LED 3
The PCB is designed to fit perfectly into the custom enclosure, with holes for LEDs and power input.
- KiCad – for PCB design - FreeCAD – for designing the case - 3D Printer – to fabricate the enclosure - (Optional) Audio signal source – via jack, aux, or microphone
