Global warming caused acidification of the sea, bleaching the corals. What was once a thriving habitat for thousands of species, now bare.

An easy to construct RGB cube with a fantastic light show in software.

This cube is easy to build with no circuit board and minimum external components; and it comes with a lot of animations and effects.

An easy to build LED cube with great animations that makes it worth the effort to build.

In this project I will show you how to build a simpler version of a 5x5x5 LED Cube. It means commanding 125 LEDs using one Arduino board

A cool 30 x 10 ft light show which includes 2 Arduino Mega boards, a hundred single-color LED strips and some SMPS full of AMPERES.

This project will show you how to fade lights, add a button to it.

This project will show you how to make a DIY flashing LED cube.

Arduino-controlled Christmas Tree lit by 150 digital RGB LED pixels. The RTC chip switches on and off the tree at the planned hours!

So, every time a make a project, it ends up looking like a plutonium based device. And this is one of them.

This project is light show made by powering 168 LEDs with an Arduino Mega and an Arduino Mini along with a Serial MP3 Player.

A simple project to show a clock on a wall with just one small laser and a rotating mirror.

This is part one of the music visualizer series. In the following tutorial, we are going to make a music visualizer.

Measure humidity and temperature levels in your home to avoid unhealthy air quality with this fun project.

This project will show you how to make a unique DIY Christmas Tree for this year’s Christmas.

Christmas is coming and you know we had to build something that would put the entire neighborhood into the Christmas spirit!

Smooth real time Fade & Dimm up to 20 LEDS with normal digital IO's This is done by an ISR routine swithing the LEDS between 1.5 and 2 Khz
