Sending Bytes to an 8x8 LED Matrix.

You’ll learn about IR protocol and how to use the IR receiver module.

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

Light up your world with these programmable fountains of photons!

Simple device to control and initialize DALI lamps.

Yet another useless Arduino clock, but i love it.

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).

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

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.

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.

Build a simple LED throwie, then make it smart with an Arduino.

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

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

A little tidbit on how to make smooth, step based colour transitions for RGB LEDs in Johnny-Five!

Receive the signal and control an LED.

IKEA PS 2014 Pendant Lamp Modification

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

Control your LED on Arduino UNO using Blynk App.

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