Make Your Own 15x10 RGB LED Matrix





Introduction: Make Your Own 15x10 RGB LED Matrix

In this video series I will present you how to build a 15x10 RGB LED Matrix. This Matrix has a width of 1.5m and a height of 1m. It consists of PL9823 RGB LEDs which are a cheap alternative to common WS2812 LEDs. I will talk about the challenges that such a project offers and how I solved mostly every problem during the build. At the end of this instructables you should be able to build such a monstrosity and also be able to control it with the Glediator software through a Raspberry Pi 2. And trust me, it looks amazing! Let's get started!

And if you are curious how I built the wood construction around the Matrix itself, then check out my previous Instructables about my LED Bar:

Step 1: Watch Part 1 of the Video Series!

Part 1 is all about how I started the project,.......with many problems. It is only an introduction and does not show my final design. You can skip it if you really don't have the time.

Step 2: Watch Part 2 of the Video Series!

This video gives you all the information you need to build your own Matrix. And you can already control the PL9823 LEDs with an Arduino Nano to produce a great light show.

Step 3: Order Your Parts!

Here is a small parts list with example sellers:

150x PL9823 RGB LED 8mm:

150x 100nF Capacitor:

1x 5V 12A Power Supply:

1x Arduino Nano :

1x150Ω Resistor:

150x PL9823 RGB LED 8mm : -

150x 100nF Capacitor:

1x 5V 12A Power Supply:

1x Arduino Nano :

1x150Ω Resistor:

150x PL9823 RGB LED 8mm :

150x 100nF Capacitor:

1x 5V 12A Power Supply:

1x Arduino Nano :

1x150Ω Resistor:

You also need:
15m 3x1.5 qmm NYM

15m 0.75 qmm solid wire

2m 5x2.5 qmm flexible wire


Step 4: Animations for the Arduino Nano!

Here are the codes that I used during this video part. This way you don't need a Raspberry Pi 2 to control your LED Matrix, just an Arduino Nano. And it already looks awesome!

Mediafire Link:

Step 5: Watch Part 3 of the Video Series!

In this final part I show you how to use the Glediator Matrix animation software with a Raspberry Pi 2/ Banana Pro/ Banana Pi/ Orange Pi.

Step 6: Order Your Favorite Single Board Computer!

Here is a list of boards that should work without a problem:


Raspberry Pi 2:

Banana Pi:

Banana Pro:

Orange Pi:

Step 7: GLEDIATOR PL9823 Arduino Sketch!

Here you can download the code which you need to upload to the Arduino Nano before using the Glediator software.

Step 8: Useful Links to Sites!

Here are some of the sites that I mentioned during video part 3:

Raspberry Pi 2 Raspian Download: Glediator Download:

LeMaker Raspian Download:

WinSCP Download:

Step 9: Commands That I Used!

Here is a list of commands that I used during the final part of the video series:

sudo passwd root (Change the password for the root user)

cd glediator/dist/ (Change directory)

java -jar Glediator.jar (Execute Glediator.jar)

sudo apt-get install librxtx-java (Install the RXTX library for Java)

export CLASSPATH=/usr/share/java/RXTXcomm.jar (Change CLASSPATH)

export LD_LIBRARY_PATH=/usr/lib/jni (Change LD_LIBRARY_PATH)

Step 10: Success

You did it! Now sit back and enjoy the light show.

hi, i made a 16*8 panel and got it to work on the arduino sketches provided with your instructions but cant seem to work with the glediator software. I connected arduino to my pc and tried sending data signals from pc to arduino with glediator, the RX shows activity but nothing happens on the board!! does anyone have any suggestions!!!!!!!!!

Does it also work with only the PC and the Arduino (without of the Rasberry PI 2)


Do you think this will work with a Pine64 board instead of a raspberry PI?

Hi!I like the project so much!!!

I have Arduino Uno,Can i uset for the project

Hi everybody!

I would love to do this project as well and I
would like to ask you something. I didn't find the PL9823 RGB LED but I
found RGB PTH LED. Will they work like the PL9823? Another question is
if there is a way to replace each led with another matrix but control it
as one led. I want to replace each led in each box with another led
matrix but control that entire matrix as one led. Is it possible? Thank
you very much!


Hi Mr Scott!! I have reproduced your awesome project! But when I powered up It lights and down in a seconds... I have added 3 wiring in ground and vdd. But it still doing it. Could you please tell me why?

I built this LED Matrix with 204 LEDs (17x12). Everything works fine but the Data signal doesn't seems to be correct.

I started with the LED on the bottom right and connected them like a snake to the top.

The upper lines sometimes do what they want.

If i test LED for LED and let a white dot run through the matrix, sometimes the LED before or after the current one lights up blue or yellow. The first LED blinks always white in this case. I tested different LEDs to be the first one, always the same.

What could be the reason?

It is a common problem that I was facing as well. Make sure your power wiring is thick and connects every LED with all the one around them (extreme case). You can also try adding a small value resistor at the beginning of each new line ( around 10ohm). And the new FastLED library also supports the pl9823 protocol. Make sure to use this one.

hola amigo, nos podría regalar una imagen de la conecxion de los led, muchas gracias

Ich sag's mal auf deutsch.

Ich habe 3 reihen mit Stromkabeln miteinander verbunden und speise den Strom ebenfalls an 3 Stellen in die Matrix ein. Also mache ich am besten noch mehr Verbindungen und schaue dann mal weiter?

Werde das auf jeden Fall mal so probieren, danke!

Mit der Abschirmung vom Datenkabel sollte/kann das also eher nicht zusammenhängen?
