Sending Bytes to an 8x8 LED Matrix.

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!

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).

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.

Because LED are fun - but addressable rocks. :)

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

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.

A simple Arduino assembly that checks temperature and sets an RGB LED from blue to red.

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

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

Everyone loved Knight Rider. I want to see more KITT scanners in the world.

Christmas is near!

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

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

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

Extremely simple project, my first even. Four buttons. Three to choose RGB values, one to choose whether to subtract or to add.

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.

LED emergency lights for use on model / toy vehicles and other projects. Uses Arduino UNO and GY-WS2812B-8 RGB LED Module from DIYmall.
