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.

Control 8 x 8 (64) LEDs using two 74HC595 shift registers as fast as possible using SPI and PORT access. (Updated 19 Jan, 2019)

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
