Some work with Arduino Nanos and a Raspberry Pi later, and he had a very acceptable LED matrix table. An attractive hack, you might say, and leave it at that. But he wasn’t satisfied enough to ...

the Arduino Nano and Micro share some similar pinout configurations. They both have two GND pins, two reset pins, one AREF pin, and three power pins (3.3V, 5V, and VIN). Their onboard LEDs are ...

The build is open-source, and designed to work with strings of 60, 120, or 180 WS2812B LEDs. An Arduino Nano is charged with running the show, capturing audio via its analog-to-digital converter.
