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:

A MCP23S17 and SSR driver board for controlling AC light bulbs 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.

Piranha LED carrier boards for use with this board are located here:

Adapter for the 96Boards.com low speed (LS) header to 40-pin IDC socket, to permit connection to a ribbon cable (usually to a breadboard). This “Alpha 1” version is pretty tight to the connector, occludes one of the 96boards mounting points, and has wonky routing (blame the autorouter) but works for me (tested on a HiKey, should work on other boards). Note that the IDC header can be placed on the same side or the opposite side of the board from the LS header; placing it on the same side keeps pin 1 as pin 1, where placing it on the opposite side swaps the even and odd pins (1<->2, 3<->4). I’m working on a smaller board with a better connector placement.
