Innovative Music Synthesizer with Multi-Mode Sound Production and RGB Lighting

The Matrix Music Box is an advanced synthesizer that utilizes an 8x8 grid of 64 buttons as its user interface for sound production and RGB lighting effects. It features three distinct music playing modes: Sweep, Gravity, and Memory, along with sound effects mimicking guitar, piano, and drum beats. The synthesizer incorporates a 12-bit DAC for audio output, a 3-axis accelerometer for interactive controls, and utilizes an LCD display for user feedback. This project highlights complex integration of various components to create a versatile musical instrument.
