In this project, we will print out Morse Code of a sentence typed in Serial Monitor by flashing LED for each word and space between them.

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

Set up an RGB LED to phase through the colors of the rainbow, or use twist knobs to make a custom color.

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

Receive the signal and control an LED.

Pedestrian walk cycle will only occur when both lights are red AND button has been pressed.

Driving a dot matrix display with Arduino using data from a Winamp plugin.

Got a 3D printer and a spare Arduino Uno or Mega? Make a working lighthouse for your home.

Show important notifications from your smartphone using a NeoPixel ring and Arduino.

New sound and light for an old retro desktop jukebox.

Learn to flash Red and Blue LED's to resemble police Lights.

Create digital dice in 15 minutes!

LED cube 4x4x4, 64 LED diode, 16 forms of work.

Automating traffic road crossing signal, will turn red only when there is some presence of pedestrians waiting to cross.

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

An Ardiuno project using NeoPixels to create slowly changing christmas light pictures and new years countdown + fireworks in my window.

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

Last year I did an awesome Christmas light show at my school using only a few Arduinos and a program called Vixen Lights.

A "Magic Cauldron" that detects spell casting and responds with dynamic lighting effects.

A very easy project with my library.

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).

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

A simple demonstration of charlieplexing: 12 LEDs are individually lit over 4 wires.

A fun project where you get colorful blinks depending on the RFID ID.
