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

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

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

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

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

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

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.

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
