Dance Floor Lighting Controller as a tribute to vintage units from LiteLab and Diversitronics. Operates 64 lights in an 8x8 matrix, just like the originals. The project “core” is an Arduino Pro Mini.
A MCP23S17 & MOSFET driver board to power LEDs with the system is located here:

If you really want to build one of these, find me online and I’ll share the code. My username isn’t hard to track down.

Uses the MCP23S17’s 16 I/O lines to address a matrix of 64 LEDs. Connectors are broken out so that there are 8 busses of 8 LEDs each.

Each PCB contains 8 individual board that you “snap” apart. Each board holds one piranha LED and a current limiting resistor. The 10-pin dual-row header uses two pins for ground (return) and the 8 remaining are each used on one board. This allows one to use a ribbon cable to access 8 LEDs in “parallel”. Originally created to build an 8x8 matrix of LEDs with 16 I/O lines.
A MCP23S17 and MOSFET driver board intended to be used with these boards is located here:
