Set up an RGB LED to phase through the colors of the rainbow, or use twist knobs to make a custom color.

Let's create a light gate using Arduino.

Binary Clock using LED Matrix module (8x8) and presenting many features: time, date, day of week, week of year and also the Moon phase!

This is my project about an Analog Clock on a LED matrix and Arduino.

Extremely simple project, my first even. Four buttons. Three to choose RGB values, one to choose whether to subtract or to add.

Built with recycled elements, high brightness color LEDs and an RGB LED. Arduino Mega 2560

By controlling the LED strip from a computer, you can do almost anything! I used it to create a dancing light show for music.

This example demonstrates how to use LDR as a switch; each time you cover the LDR, the LED is turned on (if it's off), and off (if it's on).

Got a 3D printer and a spare Arduino Uno or Mega? Make a working lighthouse for your home.

Driving a dot matrix display with Arduino using data from a Winamp plugin.

Lights that turn on when they receive an infrared signal from an old TV remote.

Cool Origami Lamp Using Arduino Uno, LED Strip, IR Sensor Module.

A lamp which changes color according to the tweets of people.

Pedestrian walk cycle will only occur when both lights are red AND button has been pressed.

Learn to flash Red and Blue LED's to resemble police Lights.

This is an original ternary digital clock running with Arduino! It's very simple and unlike anything you've ever seen!

Receive the signal and control an LED.

In this project, we will print out Morse Code of a sentence typed in Serial Monitor by flashing LED for each word and space between them.

Lightstick with various effects, "Song Programming Mode" and a smartphone compatible user interface.

Show important notifications from your smartphone using a NeoPixel ring and Arduino.

New sound and light for an old retro desktop jukebox.

Create digital dice in 15 minutes!

LED cube 4x4x4, 64 LED diode, 16 forms of work.

Automating traffic road crossing signal, will turn red only when there is some presence of pedestrians waiting to cross.
