How to use MAX7219 LED matrix (running text, display sensor data, add more LED matrix with Arduino) 

Nice simple setup. Excellent circuit. Gives me joy when something works, first time !!

Just what I was looking for - thanks for your clear video

Great and detail as always. Thanks

Excellent, I used it.

thanks for the sharing. great work on the tutorial

Thank you for your sharing!

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 .. good tutorial. could please make tutorial ( feeding message from SD card module )

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...

this was useful

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.

I didn't see any schematic for those. Please tell me about them, what is the UI_swicth?

baguss juga sih

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

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?

Bang,klo pake modul LED matrix p10 bisa??

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

How can this properly working i have matric dot 2 module 8×32 2 module

what is the budget for the material you used..each?

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?

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.

Nice brothers👍🔔🙏 13:03

can you help me i am using MPU6050 with this display and uno

🆒 Thank you so much for uploading this video. 👍👍👍👍👍 Sharing with community 🇵🇰

Thanks! Can the data be live driven? Looking for live update for support tickets counter.

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

Please make clock with that running text :)

What model of arduino you use?

Hi, Is there limitation to words?

Do you know how many of these I can daisychain together? I’d like string together like 15, like one long line

May I know how to write bus top led text?

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.

How many of these 8x8 could be connect to an Arduino? I was planning to get 16 8x8 led matrix

Is good friends.....👍👍👍

Very cool but, the control of the Matrix could be through Bluetooth or Remote Control; what do you think?

Fc16_HW is not a member of md_max72xx error, how do I fix it?

how about adding a bluetooth module so we can send the text from our phones

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 .

How can i add random and scroll animation at the same time?

can i combine three of those 4x1 led module then use just one arduino nano?

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.

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

The link for the code is broken
