29 led matrix projects

You’ll learn how to use an 8×8 dot matrix LED module with IC MAX7219. You will also learn its cascade connection & how to display shapes.

UltrasonicEyes is a fun and quirky project you can place somewhere and watch as it looks at things moving around in front of it. Freaky!

One year ago I built a simple Arduino dice with my son. We have learned a lot in the meantime and it's time for an update...

Orientation-aware 8x8 LED matrix clock

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

48x8 Programmable Scrolling LED Matrix using Arduino and Shift Registers.

A 16x32 LED matrix displaying an evolving RGB countdown 'til the new year. A surefire way to bring a New Year's Eve party to the next level!

A fun, colourful RGB LED matrix with a twist!

Get close and the Arduino is happy; go away and he gets sad.

I love swimming, but I tend to lose count of the laps, so I made this lap counter with an Arduino.

You will be able to create a small aquarium assistant which will switch on/off the light and control water parameters automatically.

A Tetris game built with a homemade 16x8 matrix.

A very basic intro into some very cool LEDs!

A funny looking robot in the form of a plant, that interacts with some sensors inputs, talks, plays music and detects human movement.

My very own binary clock based on Arduino and an 8x8 LED Matrix backpack.

Make a cheap and good looking LED matrix.

Simple but meaningful project to ask a girl to be your girlfriend using an LED matrix & Arduino. (We aren't responsible for broken hearts.)

The circuit was printed with the Electrifi conductive filament in 15 min. All 64 WS2812b SMD LEDs were attached to the circuits in 20 min.

This project connects the ADLX345 3-Axis accelerometer to display a location on an 8x8 LED matrix using the MAX7219 LED driver chip.

Get into the fantastic world of effects by making a simple design that can move with your hand by using a phone & other simple components.

Do you have a pen stand that just sits there and does nothing? Can we make it play a game/flash LEDs every time you use it? Let's find out!
