I still seem to have the old libraries… How would I archive to build this
?
You would use the library manager to update the libraries in ide 
i recently updates some libraries, my bad…@vbh
Now i see a bunch of errors on compile, can you tell me what versions of libraries your running to compile them?
Fantastic, it works out of the box.
I have also updated my code to work with the newest versions (3.0.1 for both currently) of the MAX72xx and MD_Parola libraries you can install from within the Arduino editor.
Here’s the updated version: https://pastebin.com/qaaQbfdq

Amazing 
thanks
Hey @vbh
I’m getting around to building your project - what version of the PubSubClient library did you use? I’m having issues building your sketch with the latest PubSubClient from the Arduino library.
Edit: I got this working - you need to use the old version of the PubSubClient library which is attached by the OP of this thread. The newer version use a different command structure and that messes up the code. Got it up and running now with that change.
Hey @keithh666
I have your project up and running. The text being displayed is unreadable though. I think I need to change the pins for my hardware? But I am not sure. I am very new with the esp and matrix boards.
Any help would be greatly appreciated.
Got it working. I had to change the HW type in the MDmax72xx.h
I think it is either 2.4 or 2.6. 2.4 seems to be what was included in the original download of the topic starter.
By the way; my matrix sign is still running strong. It works reliably, the only problem i have is when i make the brightness of the led’s too high, then parts of the led’s will stop working until i reconnect the power. I think this has to do with the power supply through usb being unsufficient. But otherwise no problems at all and the combination with Node RED supplying the content has proven to be very flexible.
I think it’s time for a clean writeup? Do u want to make it ? With all necessary files and so on?
mine as well, thanks to you 
Hi …I have this error…anyone can help me please
Thanks

no matching function for call to 'PubSubClient::PubSubClient(WiFiClient&, const char [12], int)'You are probably using the wrong libs for the pubsubclient use Nick O’Leary’s 2.4.0, I think that’s the version that works.
Sorry to bother you, but can you help?
What am I doing wrong?

As stated by keith666 you’re using the wrong version of the PubSubClient library. Replace the version you’re using with the older version linked.
A side question, does anyone have any suggestions on how to best join the LED matrix boards connections? I haven’t come up with anything that I have been able to make work easily.
I just soldered mine directly together rather than using wires, it works well enough if you have it in a 3D Printed enclosure since it is supported.
