INTRODUCTION:
soundBug is a series of interactive lighting devices that respond dynamically to the volume and frequency of incoming sound. An embedded Arduino system utilizes FFT (Fast Fourier Transform) to analyze the sound spectrum, translating it into varying intensities and patterns across multi-channel light bulbs. Initially developed with single-channel AC bulbs, the latest versions (v2 and v3) incorporate multi-channel DC bulbs, which can be chained to other devices, enabling expanded multi-channel lighting reactions. Since its development, this series has been utilized by various musicians, enhancing live performances with reactive lighting.

HOW TO USE:
The soundBug 2R is designed to accept both mono and stereo audio signals through its 3.5mm input jack. For optimal performance, it is recommended to use an audio mixer or audio interface to route the sound. This setup enables you to send the audio output through both the 'phones' (recommended to connect to the soundBug) and stereo speakers, ensuring a clean, controlled signal and accurate sound output for the best results.

soundBug 3.0 utilizes a form of electronics on canvas, enabling interactive technology to be presented not only as sound-reactive lights but also as paintings on a canvas. It features a 12-channel frequency spectrum, automatic LED mapping, and expandability through chained audio signals.

soundBug 2.0 features four digital (12VDC) output channels and supports six different frequency modes. soundBug 2R is a simplified version of 2.0 that automatically maps sounds to the bulbs, dynamically shifting between different frequencies at random intervals (from 200 milliseconds to 10 seconds), eliminating the need for manual button control.

HOW IT WORKS:
The Arduino system utilizes two main shields: the SparkFun Spectrum Shield and the Adafruit Motor Shield. The SparkFun Spectrum Shield allows the system to split a stereo audio input into seven frequency bands per channel and measure the amplitude of each using the Arduino's ADC. The Adafruit Motor Shield enables control of up to four DC loads, such as motors or bulbs, using TB6612 MOSFET drivers, which provide 1.2A per channel with a peak capacity of up to 3A. The frequency bands of the input sound are mapped to individual bulbs, with the mapping dynamically changing to different frequencies at random time intervals ranging from 200 milliseconds to 10 seconds.

Materials:
Sparkfun Spectrum Shield, Adafruit Motor Shield, DC 12V Dimmable Bulb, Arduino UNO R4 Minima, Power Supply 12v 3a, 3.5mm stero cable, Audio Adapter 6.35mm (1/4 inch) Male to 3.5mm, lamp base...

TECHNICAL DETAIL:
soundBug 2R requires a power supply of 12V and at least 2A. This device also utilizes a 12V DC dimmable Edison-style A60 (A19) bulb.

soundBug 1.0 uses AC voltage and analog filament Edison bulbs (120VAC, zero-cross) with a single-channel output. This version is often preferred by some musicians for its analog feel - offering smoother, warmer transitions compared to digital - along with its stronger intensity (up to 1000W) and simplicity.
