An interactive LED floor to get the dance party started

Arduino TeamMarch 27th, 2017

If you want a light-up dance floor for your next wedding or other special event, you can rent one; however, that can be quite expensive. On the other hand, you and your hacker friends can always build one. How hard can that be?

Turns out, very hard. While it may be simple to get one translucent panel to illuminate with LEDs, this 17′ x 17′ interactive dance floor used 64 panels with four lighting cells in each, for a total of 256 lighting arrays and 7,680 RGBs arranged as 2,560 addressable pixels.

Even with some advanced tools like a pick-and-place machine for PCB manufacturing, as well as a laser cutter, it still took volunteers many hours over the course of 11 months to get it working. LED control is accomplished via a Teensy 3.1, while 256 pressure switches under the surface are read by an Arduino Mega.

You can see more details of the impressive project in the video below (including a round of multi-player Dance Dance Revolution) and a few more technical details in AvBrand’s write-up here.
