Sending Bytes to an 8x8 LED Matrix.

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

Ten LEDs connected to an Arduino Uno and a potentiometer.

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

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

The LED sequencer is an easy project for beginners to learn how LEDs work.

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

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

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

Use a normal LED to sense light.

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

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

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

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

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

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

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

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

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

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!

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.

Just a basic sound sensor activated LEDs with an optional LCD for sound level data. ***STROBE LIGHT EFFECT AT AROUND 8:45 MINUTE MARK!***

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).

Three LED and a switch equals railroad crossing lights.
