4x4x4 NeoPixel LED Cube

64 WS2812B LEDs controlled by Arduino Uno with modular C++ firmware

Overview

Built a fully functional LED cube featuring 64 individually addressable WS2812B LEDs arranged in a 4x4x4 matrix. The firmware implements a non-blocking state machine using millis(), debounced button inputs, buzzer feedback, serial diagnostics, LDR adaptive brightness control, and multiple animation patterns.

Key highlights

·Non-blocking state machine architecture using millis()
·Debounced button inputs with buzzer feedback
·LDR adaptive brightness control
·Multiple programmable animation patterns
·Serial diagnostic interface
