Controlling Max7219 8x8 Led matrix by Phone with Nodemcu WiFi

In this tutorial i demonstrate how to control the max7219 led matrix display by phone over WiFi network with the help of Esp8266 nodemcu.

Made with Amica nodemcu and working fine.....
🆒 Thank you so much for uploading this video.

Thank you for your project video. I did run into an issue with timing, perhaps variation in the MAX7219 displays cause this.
My test worked on Arduino for a baseline, but not on the ESP8266 (D1 Mini), and same with NodeMCU.
After troubleshooting, the timing seemed to be the issue, as the ESP chips are way faster than the Arduinos.
The fix was to add: SPI.setClockDivider(SPI_CLOCK_DIV4);
Then it worked like a champ.

Awesome dude. Very nice

Does your SSID and Password need to have quotes around them?

[@am1manTravel]

I'm a newbie, just learning. I did not see the SPI.h in the Arduino Library. Is it built into the hardware core for the Nodemcu board, meaning it is already there?

How do you add password protection to it so only you can change the text? Also how do you show the text in other language?
Do you have video teaching how to solder that esp8266 to circuit board? I'm new to soldering.

Well done man , how about wifi clock esp8266 and 8x32 led matrix (max7219) -( just a clock no weather and no marquee) , I tried from others but no luck (differnt types of led matrix I guess and my lack of experience ) . Thanks

So I tried this code but it seems to have an issue with the Define D8, Are you using a specific version of any of the library? I have been trying to see why this is throwing the error from your code but having troubles. Can you assist in this?

[@MrBlanket011]

Hello. Maybe you already solved the issue. I had the same problem. I used nodemcu, but for the board I selected ESP-8266 general in first place. After selecting "nodemcu esp-12e" it worked.

[@alfankosh1]

i have same problem

[@wolflariosa4414]

Thanks! 😁

perfect thank you

Hi, thanks for a great guide. Any idea on how I can add a image/logo at the top above headline, I tried using but that did not compile in Arduino. Any thoughts on how to solve that? And also, do you see any risks of exposing this to the internet via a dynamic DNS and port-forwarding? Any easy way to put a password on the page?

how to set the font size to be a little bigger

[@TeguhItp]

why my code eror "s_idle"?

[@arughana]

web page is not available error, i have written my IP address which is showing in display

[@MrJayjayromero14]

Hello sir, may i ask what to change if i want the nodemcu to run in AP mode instead of STA mode? I'm new to this thank you so much

[@heikosoeder]

You find a solution?

[@anisharahajeng7811]

can i complied this script on arduino wmos r1 dmini ?
