Reactive LED Coffee Table - Arduino 2

Completion of a project. Two 24" x 26" boards (pegboard) filled with 818 blue LEDs, 160 IR emitters, and 190 IR receivers. All organized into 190 "nodes" and powered by two Arduino micro-controllers. I built the coffee table and sized the inner cabinet to accommodate these pegboard reactive surfaces. The array of white lights that you see when there are no blue LEDs on are the infrared (IR) emitters. This portion of the light spectrum is invisible to the naked eye, but digital cameras can pick them up. Simply: in person, you would not see any light until you interact with the table.

The two pieces of pegboard (as well as a good view of the wire "nest" beneath them) can be seen during testing here:    • Arduino IR Reactive LED table / board x2

IR-LED "node" power requirements determined with (led.linear1.org/led.wiz) - Good helper tool!
