It has some LEDs inside something that refracts.

Christmas is near!

Arduino controlled auxiliary saddle bag lights for a motorcycle.

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

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

A freeform circuit sculpture of a snowflake. Driven by an Arduino Nano using 18 software PWM pins.

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.

Last year I did an awesome Christmas light show at my school using only a few Arduinos and a program called Vixen Lights.

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

This project shows the integration of hardware with mobile application. The user can control equipment from his phone over the internet.

An Arduino powered Stranger Things light wall costume that can be controlled via Bluetooth serial connection to a cell phone.

A fun, colourful RGB LED matrix with a twist!

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

It's a Morse code receiver base on processing the light signals.

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).

An Arduino logo engraved in acrylic with a touch sensitive aluminum LED stand.

Three LED and a switch equals railroad crossing lights.

IKEA PS 2014 Pendant Lamp Modification

A quilted fabric clock with NeoPixels, that tells time using an Arduino Uno!

LED display with DC motor rotations.

A simple demonstration of charlieplexing: 12 LEDs are individually lit over 4 wires.

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

Receive the signal and control an LED.

Everybody here loves binary clocks. So do I, so I made one for myself.
