An interactive artwork that translates light into living memory. Using an Arduino photoresistor, the system continuously measures ambient light levels (0-1023 range). When darkness is detected (sensor covered), colorful particle systems spawn and generate corresponding musical notes from a pentatonic scale.

Technical Stack:

• Frontend: p5.js (visual rendering + p5.sound for synthesis)

• Hardware: Arduino Uno + photoresistor voltage divider circuit

• Communication: Web Serial API for real-time sensor data

• Audio: 12 independent sine wave oscillators mapped to color/frequency pairs

Behavior: Particles exhibit emergent flocking behavior, connecting via proximity-based lines. Each of 12 pastel colors corresponds to a unique frequency, creating generative harmonies. Extended darkness (>1.5s) "preserves" memories, making them glow brighter and resist light-induced decay.
