Simulate a traffic light using an Arduino and LEDs! This project is super cool to watch and easy to make!

Yet another useless Arduino clock, but i love it.

Uses a photo resistor to determine whether a room is bright, average or dark. It shows this using 3 LEDs and/or the serial monitor.

Use Arduino to run a spectacular Christmas light show. (Both in English and Spanish, en Ingles y Español.)

Frustrated with the prices for high quality grow light systems? Let's design a fully controllable, easy to adjust, open-source LED panel.

Because LED are fun - but addressable rocks. :)

RGB LED backlight with audio signal visualization for room/desk backlightning...

Set up your Arduino and Raspberry Pi to control lighting and animation on an RGB LED strip from your smartphone or PC.

The device displays animated GIF pictures on a rotating cylinder. The GIF pictures can be downloaded from a PC via Bluetooth.

Arduino based 3D LED Cube (3x3x3) which can produce any light pattern with 27 LEDs.

Build a beautiful “infinity mirror” Illusion that you can control by changing this mirrors' orientation. Rotate for changing colors!

A nice looking analog style LED POV clock.

An animated cube made with 512 RGB LEDs driven by an ATmega328.

Using the power of motion, swipe in 4 directions to change the color of an LED!

This project will let you have some fun playing with colors using Arduino analog input / output. Change colors with just a twist.

A fun, interactive project for makers new to Arduino. Control the brightness of an RGB LED with Potentiometers, with on/off switch built in.

I made two NeoPixel sabers controlled by Arduino, with plumbing part hilts that look nice, and animated party modes.

This project allows the user to create their own light animations! Can modify each frame, the speed, and loop count.

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

An interesting light display using 64 glue sticks and 128 WS2812B RGB LED strips.

Ten LEDs connected to an Arduino Uno and a potentiometer.

Low-cost outdoor lights with DMX control.

An 8x8x8 LED cube is a visual treat with 3D effects and patterns.

Just a basic sound sensor activated LEDs with an optional LCD for sound level data. ***STROBE LIGHT EFFECT AT AROUND 8:45 MINUTE MARK!***
