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!

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 (http://fastled.io/) 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!
