Get Groovy With An LED Arduino Disco Floor

Get groovy in the new year with an LED disco floor. via instrucatbles

This project is inspired by the Pixel Drop Ceiling by hockeyman271 and would not be possible without referencing that instructable.

This LED Disco Floor uses WS2801 36mm RGB LEDs that are computer controlled via an Arduino. I chose the 36mm WS2801 due to their lower profile (5mm deep). This allowed me to place them alongside my floor tiles.

Arduino Uno R3
Arduino Proto Board
USB 2.0 A to B Cable

Mini Breadboard

UK Plug and Cable (maybe use and old kettle lead)

36mm WS2801 LED’s ( I found these cheap on Ebay from China)

12V 5A Power Switch

Lexan MARGARD Clear Plastic Polycarbonate Sheet 5mm (Offcuts on Ebay)
9mm Thick, 21mm Wide wood strips
Translucent White Self Adhesive Vinyl
A Windows PC/Laptop to run Jinx!
LED Wire
The material used for the grid is entirely up to your preference, I have minimal woodworking skills but the grid structure holds up well. I was advised to try the Lexan Margard due to it’s high strength and “abrasion resistance” and it has done a good job so far. The translucent vinyl was a bit of a last minute choice and I struggled to source exactly what I wanted. I was ideally after a frosted look but struggled to find one that was translucent not opaque. The amount of diffusion achieved was satisfying even with how close the LEDs are to the vinyl.
