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.

Receive the signal and control an LED.

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

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

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).

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

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

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

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

Three LED and a switch equals railroad crossing lights.

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

A lamp which changes color according to the tweets of people.

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.

Can a wooden block, wrapped in LED strips be turned into Rubik's cube?

This an automatic morse code which can be used in different situations and projects like ( ROV, Drones ..etc )

Lights that turn on when they receive an infrared signal from an old TV remote.

Create digital dice in 15 minutes!

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

This is a wooden Christmas tree I made, using LEDs for the star at the top and the garland on the tree.

An Ardiuno project using NeoPixels to create slowly changing christmas light pictures in my window.

By controlling the LED strip from a computer, you can do almost anything! I used it to create a dancing light show for music.

LED display with DC motor rotations.
