LED cubes are true 3D displays that work by lighting up points in a 3D lattice of LEDs.

On the 3D display you can produce some truly mesmerizing animations. This tutorial will walk you through creating an LED cube for yourself that is completely self-contained and…

Well, someone had to do it. And first prize goes to Heineken with their new Heineken Ignite Bottle, featuring LED lights and sound/motion activation sensors. Heineken hosted a VIP party to unveil the new interactive beer bottles, which light up in time to beats of the music and also on motion when people drink from the bottle… And when I say someone had…

Researchers from the University of Illinois and University of Washington have developed a wireless implant that uses LEDs thinner than a human hair to produce light, stimulating their test subjects to create dopamine, a chemical released in the brain during pleasant experiences. By…

In this tutorial you will see how to make display a scrolling text message in a led 8x8 matrix with basic components and Arduino. The message can be altered changing the sketch.

Materials List: 

1 x Arduino Uno R3

This pocket watch was made with an ATmega645P to control the array of LEDs, an RTC, two buttons to activate and alternate operation modes, a vibration motor, a buzzer  and a rechargeable lithium coin cell battery charged by an USB connector. The biggest challenge of the design was driving…

This tutorial will show a simple way to control an RGB LED with the Arduino. An RGB is a LED which reproduces three colors: red, green and blue. It has four terminals, one for each color and the GND. It is possible to illuminate each one of the colors with different…

Ch00f created this cool LED canvas, where you can draw with laser. The device works reading LED as a light sensor between screen refreshes. So, the microcontroller can detect the laser and the turn the corresponding LED on.

William McShane from PumpStationOne created a clever LED display with conductive ink on top a magnetic ink board. With this, he could place LEDs anywhere, making a display.

I'm a little out of my league here - I'm an artist who works with electronics. This was a project I did in 2010. Caged is an 8x8x8 cube using a boarduino and some custom boards we made to house the LED drivers and microphones. Caged responds to anger (decibel level) using Conway's game of life programming.

There is a lot of information on the project…
