Let's create a light gate using Arduino.

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

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

New sound and light for an old retro desktop jukebox.

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

Can a wooden block, wrapped in LED strips be turned into Rubik's cube?

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

An Ardiuno project using NeoPixels to create slowly changing christmas light pictures and new years countdown + fireworks in my window.

This is a wooden Christmas tree I made, using LEDs for the star at the top and the garland on the tree.

A very easy project with my library.

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

Traffic lights system for a two-street crossing with pedestrian lights, controlled by Arduino.

In this project I made a Morse code transmitter using Arduino and Winform application.

Using one byte to hold all the color data for a single RGB LED.

It's not a light bulb, it's three LEDs attached to what (sort of) looks like a light bulb. All controlled by a mini-touch kit.

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

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

A cool way to build an Arduino warm/ cool white lamp, based on the Octowide Digital Light.

Receive the signal and control an LED.

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

A simple Ping Pong game played on a NeoPixel Ring with Arduino.

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

Compass lamp that changes color by rotating.

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).
