Make Your Own 10x10 LED Matrix





Introduction: Make Your Own 10x10 LED Matrix

In this project I will show you how to combine commonly available WS2812B RGB LEDs with an Arduino Nano in order to create a colorful 10x10 LED Matrix. Let's get started!

Step 1: Watch the Video!

The video gives you all the basic information you need to create your own LED Matrix. In the next steps however I will provide some additional information to make the recreation of this project even easier.

Step 2: Get Your Parts!

Here you can find a parts list with example sellers:

WS2812B LEDs:

5V 4A Power Supply:

DC Jack:

Arduino Nano:


WS2812B LEDs:

5V 4A Power Supply:

DC Jack:

Arduino Nano:

WS2812B LEDs:

5V 4A Power Supply:

DC Jack:

Foam Board:

Arduino Nano:

Home Improvement Store:

4mm beech plywood

2.5mm opal acrylic glass

stiff 1.5mm^2 wire

flexible 0.75mm^2 wire

Step 3: Build the Matrix Case/ Do the Wiring!

First off you need to create the foam board grid (see the attached pictures). Then you need two 24.5x24.5 cm squares out of beech plywood and one made from acrylic glass. The last part of the case are the sides. I chose dimensions of 4.8x25.5 cm. I used the extra centimeter to create rectangle patterns on both ends of each side in order to lock them together. The rest of the case build and the wiring is explained in the video.

Step 4: Upload Your Code!

Here you can download an awesome collection of different animations. But don't forget to copy the FastLED library ( in your Arduino folder before uploading the code. Feel free to create your own code as well and share it in the comment section.

Step 5: Success!

You did it! You just created your own 10x10 LED Matrix!

Bruh...we don't have the LED you have used in our part.
What can be the simplest alternative to the LED you've used?


Nice Project! I tried to build ist, but something went wrong. The LEDs do not light up. Could you send me the full schematics with the Matrix please?

How can I determine the current requirements for a 23 x 23 grid?

Hi, what is that black material which is used to make the fields for LEDs?

1.aun no entiendo como hacerlo

Needs to at least 5v 13.5A 67.5Watts to power all 225 LEDS

(Well for the ws2812B anyways)

Hello Scott,

whats is the light transmittance of the acrylic glass? 40% ?

If i use normal RGB leds what it will change?(sorry for bad english)

Yes, they need to be individually addressable, like the ws2812B, or 2812, 2811..
