8×8×8 LED Cube
8×8×8 LED Cube
A 512-LED cube driven by an Arduino Nano using 74HC595 shift registers. I designed the PCB in KiCad, wrote the multiplexing firmware in embedded C, and programmed several 3D animations plus a sound-reactive mode.
What I learned:
- PCB layout and soldering at scale
- Multiplexing theory
- Timer interrupts and PWM
