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

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.

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.

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

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
