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.

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

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.

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

Now, you can control your light system in your home using your voice , by talking to your systems which to turn on and which to turn off

Because LED are fun - but addressable rocks. :)

Portable LED panels let you dress us like your favorite 8-bit video game characters.

You just bought a RGB LED strip kit and you would like to get rid of that cheap hand-held IR remote and to have REAL control.

Using the microphone of your mobile phone to control the led cube according to the loudness (decibels).

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

Control RGB or RGBW single-wire addressable WS2811, WS2812 or SK6812 LED strands up to the limits of your power or Micro-Controller memory.

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

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

Build a convincing artificial fire effect for the holiday season using NeoPixel LEDs, an Arduino UNO, and a cool mist module.

I taught a class on Communication Systems using programming, machines and Morse code.

Control an RGB LED strip with an Arduino Nano.

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!

Learn to use Bluetooth wireless to control all kinds of AC devices from your smartphone.

How to make a 7x7x7 LED cube with Arduino.

In this project, we'll combine a gyroscope and NeoPixels to build a device that lights LEDs corresponding to the angle of inclination.

A nice looking analog style LED POV clock.

The classic whack-a-mole game using LED lights and a joystick.
