Christmas Tree enclosure for sound activated light

thingiverse

I'm still fine-tuning this design but I thought I'd share it online for anyone looking for a unique gift idea for Christmas. The top section is designed to accommodate lighting components, with the circuitry neatly contained within the box at the bottom. The decorative grill up front serves as a protective cover for the microphone in my project, which responds dynamically to variations in noise levels and silences by altering its patterns. There's ample space inside for an Arduino Nano board and additional circuitry, such as an audio amplifier that I've incorporated specifically for the electret mic.
