Microphone, Arduino, and LED strip to express the sound with light, together with hardware developer who likes to make physical computing, new media art, and IoT. An Arduino ws2812 8 band led spectrum analyzer was produced.

ws2812 LED strip (144 LED / 1M), Arduino pro mini 5V 16MHz, Breadboard, Microphone, 1 Capacitor 16V 2200uF, 2 0.1uF, 2 Resistance 10KΩ, 1 100KΩ, NPN Transistor 2N2222 , 5V 4A Adapter 5.5pi / 2.0mm, hc-06 bluetooth module, jumper wire, DC jack, header pin, hardboard

Arduino Fourier transform: Decomposes a waveform, such as a voice, into a fundamental frequency (basic sound) and each frequency of its regular multiple (each harmonic). A method of calculating how much of a wave contains which frequency component.

In this workshop, the micro-input sound is decomposed into frequencies using FFT (fast fourier transform), and the sound of each frequency from low to high is represented by LED.

Arduino 8 Bande de Neopixel Bande Led Circuit Analyseur de Spectre
Microphone, Arduino et bande LED pour exprimer le son avec la lumière, en collaboration avec un développeur matériel qui aime faire de l’informatique physique, de nouveaux arts médiatiques et de l’IoT. Un analyseur de spectre à 8 bandes Arduino ws2812 a été produit.
ws2812 Bande LED (144 LED / 1M), Arduino pro mini 5V 16MHz, Breadboard, Microphone, 1 Condensateur 16V 2200uF, 2 0.1uF, 2 Résistance 10KΩ, 1 100KΩ, Transistor NPN 2N2222, Adaptateur 5V 4A 5.5pi / 2.0mm, hc -06 module Bluetooth, cavalier, prise DC, broche d’en-tête, panneau dur
Transformée de Fourier Arduino: décompose une forme d’onde, telle qu’une voix, en une fréquence fondamentale (son de base) et chaque fréquence de son multiple régulier (chaque harmonique). Une méthode de calcul de la quantité d’une onde qui contient quelle composante de fréquence.
Dans cet atelier, le micro-son d’entrée est décomposé en fréquences à l’aide de la FFT (transformée de Fourier rapide), et le son de chaque fréquence de bas en haut est représenté par des LED.
