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

Using 10K Potentiometers + 16x2 LCD w/ I2C backpack (optional)

An interesting light display using 64 glue sticks and 128 WS2812B RGB LED strips.

Build a simple LED throwie, then make it smart with an Arduino.

You can add LEDs to your cross-stitch project using an Arduino LilyPad and conductive thread.

Sending Bytes to an 8x8 LED Matrix.

Lightshow created from a cylinder of 288 RGB LEDs.

Use the Arduino Due to control a large LED flat panel display. And the software to create and solve mazes on it.

This project combines the WS2812B RGB LED matrix and PIR motion sensor to greet visitors with a text.

This project allows the user to create their own light animations! Can modify each frame, the speed, and loop count.

Come and design a traffic light system on your own!!

This project uses the Arduino Nano 33 IoT, the Arduino IoT Cloud, E1.31 (streaming DMX) and Alexa to control 12 volt WS2811 LEDs.

Great Scott! It's a Flux Capacitor powered by an ATtiny85.

You’ll learn about IR protocol and how to use the IR receiver module.

How to make a 7x7x7 LED cube with Arduino.

An 8x8x8 LED cube is a visual treat with 3D effects and patterns.

An animated cube made with 512 RGB LEDs driven by an ATmega328.

Using LED and phototransistor to transmit sentences between two pc

Hello guys in this article, I am going to tell you about the making an easy Arduino POV Clock. I have made a mini POV display using Arduino

You'll learn how to create a display led to print message through Bluetooth.

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

Built with recycled elements, high brightness color LEDs and an RGB LED. Arduino Mega 2560

So far I was controling those matrixes with multiplexing. In this video I would use MAX7219 chip to do it

Last year I did my first version of my Automatic musical (Christmas) Lights which worked super great but It came with some drawbacks.
