Sending Bytes to an 8x8 LED Matrix.

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).

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

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

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

This project will let you have some fun playing with colors using Arduino analog input / output. Change colors with just a twist.

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

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

Use your HTML and javascript skills to create your own, genuine smartphone remote app for Arduino (and all its compatibles).

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

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

The TrafficLight is a project that has Arduino-powered LEDs Blinking like a traffic light.

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

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

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

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

Use a normal LED to sense light.

Control your LED on Arduino UNO using Blynk App.

Ten LEDs connected to an Arduino Uno and a potentiometer.

Binary Clock using LED Matrix module (8x8) and presenting many features: time, date, day of week, week of year and also the Moon phase!

Receive the signal and control an LED.

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

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!
