- Do you have any idea what projects we could make with this LED matrix? leave your comment below and let's make it in the next video.
In this video, we learn how to use the MAX7219 LED matrix with Arduino. And we learn how to make running text, display sensor data to this LED matrix, and how to add more modules so the display becomes longer.

Nice simple setup. Excellent circuit. Gives me joy when something works, first time !!
My words are going backwards on using one board, how do I change direction? like being behind the words.
This video did help me out big time, now hard to get the displays.
Great and detail as always. Thanks
What model of arduino you use?
I would like to see 2 ESP32 using ESP Now. One transmitting temperature and the other displaying the temperature on a scrolling display and showing when the transmitter fails.
thanks for the sharing. great work on the tutorial
Thanks!
Please help. I'm using only 1 device (8x8).
Scrolling text is working but it has mirror image problem. Each individual letter is mirrored.
How to fix?
Please make clock with that running text :)
Thanks! I will
Nice brothers👍🔔🙏 13:03
Fc16_HW is not a member of md_max72xx error, how do I fix it?
You have to look for the correct Parola library that has this function. From what I saw, it's calling FC16_HW instead of Fc16_HW (capital C).
Hi, Is there limitation to words?
can you help me i am using MPU6050 with this display and uno
Thanks! Can the data be live driven? Looking for live update for support tickets counter.
Sure
how about adding a bluetooth module so we can send the text from our phones
Yeah, that's possible. Maybe in next video. Don't forget to subscribe so you won't miss it
Great tutorial thank you sir...Hello sir, I'm working on a project called wireless notice board, using aurdino, two Xbee series 2c, 8*8 dot matrix board (4 in 1) for the display. The aim of the project is to wirelessly update the message scrolling on the dot matrix board using the Xbee. One Xbee is connected to the Arduino, the matrix board is also connected to the Arduino (I don't know if my connection is Correct) then the Arduino is connected to the laptop through USB, the second xbee is connected to another USB port. I use the XCTU software to check if the connections between the two Xbee is okay, I can send a message wirelessly to the other Xbee and vice versa... to command it to update the matrix board is my problem here please help me guys. I want to summit the project in school next week

baguss juga sih
Is good friends.....👍👍👍
Opone sing good mas?
@@miliohm jowo ta.......pemula om...lagi belajar...
@@paijokampret4433 siap mas, podo lagi sinau juga
The link for the code is broken
Sorry, we have problem in server. You can try again in some minutes.
can i combine three of those 4x1 led module then use just one arduino nano?
Sure, just solder the end of module to another module. Then define your led size in sketch
Very nice but what happens if you disconnect from power and then reconnect to power? Will it remember everything and continue displaying your last scrolling message? Or will you lose it and have to go back and reenter the message every time?
It would be awesome if you could show how you did that Pacman eating the text. I would like to have a real time clock and Pacman eating the clock time. That is my goal, any help much appreciated! Thank you
Would like to see tutorial on:
How to turn this to program via your iphone, so no need for data cable.
And a way to save different statements, that can be recalled via different input switches.
Hello sir i have problem my led matrix and geekcreit uno 3 board tell me please how can i download the in my geekcriet uno board
How can this properly working i have matric dot 2 module 8×32 2 module
I didn't see any schematic for those. Please tell me about them, what is the UI_swicth?
Just what I was looking for - thanks for your clear video
Thanks!
thank you .. good tutorial. could please make tutorial ( feeding message from SD card module )
what is the budget for the material you used..each?
May I know how to write bus top led text?
Bang,klo pake modul LED matrix p10 bisa??
Hi, Realy nice totorial (explained very well) but i'm having a problem uploading code (Error message below) anyone have any idea why im getting this error ? Thanks
Arduino: 1.8.19 (Windows 10), Board: "Arduino Nano, ATmega328P"
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x21
Try uplug the USB and try again.
If you are using a blue Chinese clone of the Nano, you need to choose ATmega328P (Old Bootloader) under Tools/Processor.. HTH.
Excellent, I used it.
sir, i want to ask when we connect this led matrix to arduino and then we connect them both with PC to upload program, does the matrix LED turns on automatically or not. In my case, when I'm connecting both the module with PC, some part of the LED turns on and some are off. This is my first project and i have very basic knowledge about electronic and nil about coding.
yes.
i am using parola_scrolling but when i try to upload it to the Arduino it comes up with error messages saying the sketch cannot upload
.
What does exactly it said?
Do you know how many of these I can daisychain together? I’d like string together like 15, like one long line
It's already told in video. Watch carefully
🆒 Thank you so much for uploading this video.
👍👍👍👍👍
Sharing with community 🇵🇰
Thanks!
Next project related to this could be parola clock
How many of these 8x8 could be connect to an Arduino? I was planning to get 16 8x8 led matrix
Not sure, but I think 16 Pieces still work
Hi, hey I have to say the first seconds I was so close to change the video, but then, I undestand every word you said and I could make my own running text for my channel, I will Use it in my next video, thanks for the usefull information!!! I speak spanish man!
Thank you! That means a lot!
@@miliohm I've just upload it, check it!
@@alonelyowl3709 that's beautiful 👍🏻
Numpang tanya bang, saya kan bikin external / extra display buat timbangan digital via serial communication, ic pakai max7219 dan LED 7segment, sewaktu mulai hidup, angka di timbangan 0, di display juga 0, sewaktu ada beban di timbangan misalnya 1000 di display juga menunjukkan 1000, sewaktu beban kembali ke 0,angka di display tidak mau kembali ke 0 kenapa ya bang?
Kalo saya coba kode yang sama dengan ic TM1637 tidak ada kendala bang padahal.
Mohon pencerahan nya.
Programnya bagaimana? Coba dishare programnya biar saya cek
@@miliohm , ini sketch nya bang...
#include "DigitLedDisplay.h"
//LedControl lc=LedControl(12,11,10,1);
DigitLedDisplay ld = DigitLedDisplay(12, 10, 11);
String dataIn;
String dt[10];
int i;
boolean parsing=false;
void setup() {
Serial.begin(9600);
dataIn="";
// led 7segment max7219
ld.setBright(10);
ld.setDigitLimit(8);
}
void loop() {
if (Serial.available() > 0) // tampilkan data ketika menerima data dari serial monitor:
{
char inChar = (char)Serial.read();
dataIn += inChar;
if (inChar == '
') {parsing = true;
}
}
if(parsing)
{
parsingData();
parsing=false;
dataIn="";
}
}
void parsingData()
{
int j=0;
//inisialisasi variabel, (reset isi variabel)
dt[j]="";
//proses parsing data
for(i=1;i
Very cool but, the control of the Matrix could be through Bluetooth or Remote Control; what do you think?
yes, we can do that in next video.
@@miliohm Thank you, I'll be waiting! I will subscribe.
Thank you for your sharing!
Thank you!
How can i add random and scroll animation at the same time?
random animation?
@@miliohm yes PA_RANDOM with PA_SCROLL
this was useful
Thank you!
hello, i want to see in your tutorials if it's possible to make a digital clock with gps syncronization with dates and temperature , power up by a photovoltaic panel....clock, dates and temperatune need to change between some interval, and the led light need to dim out if is night time...
