This interactive LED coffee table reacts to whatever’s on top

Arduino TeamOctober 16th, 2020

The YouTube team “Ty and Gig Builds” recently decided to make their coffee table a little more interesting, adding a chain of 96 addressable LEDs underneath its clear surface. This would have been neat enough by itself, but their project doesn’t just stop there and instead embeds 154 IR emitters and 154 IR receivers, allowing it to react to what’s on top.

The setup, as you might imagine, required a lot of wiring along with custom shift register and multiplexer boards to accommodate its vast I/O needs. These discrete I/O are eventually funneled down to an Arduino Mega for control, creating a one-of-a-kind table that should make for a great conversation piece while holding coffee and other knickknacks.
