JOIN THE GIVEAWAY OF SOUND REACTIVE CUBEIntroduction
Today we are going to make a sound reactive wooden cube, which changes color in perfect sync to the surrounding sounds or vibration.
Things required
- Arduino: I'm using a Nano because of its small size
- Addressable LED: I'm using UCS1903B, 5V
- Mic module
Working
- The sounds will be picked by the microphone module and fed to the Arduino analog input.
- Then using the received analog values we will change the colors of the LEDs randomly.

Acoustic Spectral Illumination Hub
A beautiful and fun aesthetic project that transforms any room by pulsing a translucent cube with colors that react to the surrounding music.
- Envelope-Follower Analog Analysis: Uses a high-gain microphone module. The Arduino captures the audio signal and perform a "Peak-to-Peak" amplitude calculation every 20ms to identify the music's "Beat."
- Hue-to-Amplitude Linear Mapping: As the music gets louder, the Arduino transitions the color of an internal RGB LED or WS2812B pixel. Low volumes might be a deep Blue, while louder peaks trigger a vibrant Red strobe.
Aesthetics
- Soft-Fade Transition Filter: Includes a software low-pass filter on the color data. Instead of "Jumping" between colors, the cube "Breathes" and fades smoothly, creating a much more premium and relaxing visual effect.
