What does one do with over 1,000 LEDs, white acrylic, and 288 IR sensors? If you’re Redditor “jordy_essen,” you create an interactive light panel.

In one mode, the user pull a reflective tool across the sensors to draw a paths, with potentiometers implemented to select the color. It can also be set up to play a sort of whack-a-mole game, where one has to activate the sensor in the same area where it illuminates.

For this amazing device, jordy_essen uses not one, or even two, but six Arduino Mega boards to drive the LEDs directly — in turn controlled by a webpage running on a Raspberry Pi. If that wasn’t enough hardware, an Uno is tasked with taking inputs from the color potentiometers. 

It’s a brilliant project in any sense of the word!

If you need another idea for how to creatively diffuse LED lighting, then look no further than the “Light Me Up!” project by Hyewon Shin, Eunjeong Ko, and Junsung Yi. 

Their setup uses 312 3D-printed and laser-cut light triangles, each of which contains a trio of RGB LEDs. Users select the desired light by pressing the triangles themselves, via buttons concealed beneath the main assembly. Several Arduino boards are used to control the massive structure.

With such an involved triangular display, a number of interesting 3D-like shapes and even words can be created by users. Alternatively, smaller triangle arrangements can also be constructed using the same build concepts. 

This project has several triangles that form a hexagonal shape. So you can create stereoscopic patterns according to how you design light! Just press each piece and various colors will be gradated, and when the color you want comes out, just hit the hand you pressed and it will continue to shine beautifully with the color you wanted!

Check out its triangular luminescence in the videos below!
