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!

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. :)

Receive the signal and control an LED.

IKEA PS 2014 Pendant Lamp Modification

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.

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.

This is my project about an Analog Clock on a LED matrix and Arduino.

In this project, I am going to demonstrate how to use a potentiometer to dim LEDs.

This project shows the integration of hardware with mobile application. The user can control equipment from his phone over the internet.

Persistence of vision is an optical illusion, it works on a simple phenomenon how our day to day television works.

Ten LEDs connected to an Arduino Uno and a potentiometer.

NeoPixel's are awesome you can control hundreds, thousands, millions of lights with 3 wires (pwr, signal, gnd). Let's learn how to use them!
