A simple gesture-controlled interactive table light, which can encourage kids towards making.

In this project text is transmitted between two arduinos by using a LED and a LDR.

DIY light based transmission between two Arduinos using LED and LDR with custom communication protocol.

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

LED indicators to show Dark or Light Level

let's build a vu meter using arduino

Turn on and off the lamp using IR sensor, change lamp color and brightness with button and potentiometer.

Control a Neopixel band with an HC-05 Bluetooth module.

A cool timer gadget to teach your kids about washing hands for twenty seconds.

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

Because LED are fun - but addressable rocks. :)

Its a RGB led controlling using a Processing IDE visualizer. As we move the cursor from visualizer the color of RGB led will change.

Use an Android device to control the color of a NeoPixel via a Bluetooth connection.

The short project for beginners to get some practice in using LED lighting with the sound sensor.

Got a KY-016? Stick it straight onto your UNO and start attracting unicorns! No soldering. No schematics. No freaking Fritzing.

A cheap DIY version of Nanoleaf RGB LIGHT with ATtiny85 and WS2812 RGB strip.

Using Teensy (small Arduino) to power NeoPixels off of an electric skateboard battery.

An alarm that triggers a siren sound an police lights when the beam of light is interrupted.

Translate music to a dazzling light show with this customizable light controller project. Great for DJs, parties, and 1:1 shows!

Why you can blank, void setup()

This project will show you how to use an RGB LED.

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

Learn how to make a 3D-printed RGB lamp using a WS2812 LED strip.

I soldered SMD LED directly to wire and made them into THT LED, then used an Arduino to fade them.
