There's a lot to love about the MAX7219 LED matrix module. Each module is a 4 unit 8x8 dot matrix running on it's own MAX7219 IC. This display works great as a marquee, a clock, a temperature display, as info signage, and more! If this module is no large enough for you then just daisy chain more module together. I'm no sure of the max number of modules you can chain together but I know you can add at least 4 of these modules (or 16 8x8 units) together for a larger display. I'm pretty excited about this module and look forward to incorporating it into some future projects.
In this video, you'll see how to make your own led matrix display using the max7219 IC. You'll be able to make your own 8x32 led display and program a LED display for another fun DIY Arduino project.
I purchased these on Amazon but you may want to check Ebay if you're not in a hurry to get them. I purchased mine from Amazon and only 1 worked. Was it user error or was it just a faulty module? - who knows. I will purchase a couple more from another vendor because these displays could be used in a variety of projects, they make a great Arduino project for beginners, and they are fun to learn with.
Thanks for watching!

This video helped me out tremendously. Thank you. You just got a new subscriber here.
Awesome, thank you! These matrix modules are a lot of fun.
Thank you! This video helps me a lot.
Awesome! Thanks for the message and good luck with your project
nice!
Thanks Heiko! These LED matrix modules are awesome~ Have a great weekend! 👊👊
My only question is when connecting two displays together, how do I get the VCC, GND, DOUT to DIN, etc. to actually stay together? Is there a female adaptor that would go on the board so I can directly plug the male into the female? I have three 8x8 that I need to connect together to make a 8x24 display. I'm basically just asking how do I connect them when they are directly next to each other?
My favorite was is to use straight pin headers, not the curved ones they give you, and connect them using a pin header jumper cap. They keep everything close and they are easy to remove later if you want. There are other ways but this way is the cleanest look i think.
@@BMonsterLaboratory Alright thanks. really good and helpful vid btw.
@@henrytheg-shep5635 thank you!
@@BMonsterLaboratory So I have my matrix boards. My only concern is are you sure the jumper pin caps aren't going to prevent the led matrix from coming down all the way? The pins seem to be a bit long too
@@henrytheg-shep5635 I'll post a picture to the facebook page this evening if it would be helpful
sir, how to display two different text SIMULTANEOUSLY, in two DIFFERENT 8 by 32 max 7219, using SINGLE ARDUINO BOARD. please. in 1st 7219 i want to display name of organization. and in 2nd board i want to display date and time.
hi there! Download MD_Parola library. Define Max_Devices as 8. There are many examples to get you started. You can upload the display example or any of the others to your Arduino - they're a huge help!
sir i need to add the library. unfortunately i cannot find a libraries for my led matrix. please send me. thank you.
Hi there! If you're using Arduino IDE 2.0, go to the library tab on the left and search MAX7219. You can download it here. That's the easiest way
How would I go about replacing the text with a variable like "points" this library doesn't play well with variables
Hey there! Do you just want "Points" to scroll? Do you want anything else? How many 8x8 matrix modules are you using?
Are you using these libraries?:
#include
#include
#include
in a 8x32 matrix module make sure to include this:
#define MAX_DEVICES 4
and:
myDisplay.displayScroll("POINTS", PA_CENTER, PA_SCROLL_LEFT, 100);
I hope that's helpful - happy to help if you still need it. good luck! 💪
If you want a bigger display, also check out Teensy 4.1 - this board works great with LED sings if you have them powered correctly. th-cam.com/video/oMlgBs5TzYA/w-d-xo.html
@@BMonsterLaboratory In that format, yes but I need a variable(Points) that displays a value that is constantly changing via other code, I just need it to display, for example, id have: int Points = 1; I need 1 (or stored value) to display. there's not much information out there on this topic unfortunately.
When i connect my board with my pc matrix display's led doesn't even on why???
Pls rply...
hey there! It sounds like you may need to run MD_MAX72XX_Test.ino to help figure out which hardware type to use in code. go to the example code in the MD_MAX72xx library and run the test. open the serial monitor and follow the directions. It will ask questions about what you see on the matrix. After you answer questions it will tell you what to put for the hardware type - it could be PAROLA_HW, ICSTATION_HW, GENERIC_HW, or FC16_HW. for me it's usually FC16_HW. I hope this helps. It can be frustrating at first but once you get it, it's pretty cool. sorry about the late reply....big trip coming up soon. Best of luck to you 👍
Hello can you tell the components which is used i am unable to understand it in video
hey there! For this, all you need is arduino, jumper wires, breadboard, breadboard power supply, and the MAX7219 LED Module. 👍
@@BMonsterLaboratory thankyou so much
@@user-ow3no5lx1f you're welcom. Good luck with your projects
man i want the copyright cause u use my name :) but ty now i can do my school homework
Hi ShaSh! Which name are you referring to? I Hope the video was helpful and you're enjoying Arduino. Keep up the good work!
What is pin 13 called
Hi there. In the video I used the LED module clock pin at pin 13. Pin 13 is a digital pin on your Arduino. It is also connected to your onboard led.
Can we display image on that
Sure! What do you have in mind?
@@BMonsterLaboratory to view image or video
Check out led matrix studio. Also check out MD_MAX72XX library. There are some good examples there. If you get stuck, let me know
Hi, Wondering if there is any chance of getting the full Script for this, please
Hey there! The code I used is posted on Facebook. go there and search #8x32max7219 - check the comment section. I have 2 different sketches posted there. A lot of the time it's too long to post here. hope that helps! 👍
@@BMonsterLaboratory Hi, from someone is just starting with ARDUINOs and stuff, I am looking at JUST ONE, SINGLE 8x8 Matrix to show a NUMBER, as in 1 or 2 or 3 and so on to 0, in total 10, I believe there will a number of the same code with this, so I am willing to except just ONE TO START and I may be able to ADD THE REST. THANKS
@@graemewilson4126 sounds good! Try this. #include

#define CS_PIN 10
#define MAX_DEVICES 1
MD_MAX72XX mx = MD_MAX72XX(HARDWARE_TYPE, CS_PIN, MAX_DEVICES);
// Define the bitmap for the number 1
const uint8_t num1[] PROGMEM = { B00000000, B00000001, B00000001, B00000001, B00000001, B00000001, B00000001, B00000000 };
void setup() {
mx.begin();
mx.control(MD_MAX72XX::INTENSITY, 2); // Set intensity (brightness) level

@@BMonsterLaboratory sorry have copied and pasted this but what I believe is it format, I have it wrong as trying to VERIFY came back a error, so I need to have the actual code, with just the one number - please
