In this guide, we will learn how to use the 8×32 MAX7219 Dot Matrix LED Display with Arduino. The 8×32 LED matrix module with MAX7129 LED driver is compatible with Arduino Board & other microcontrollers. An 8×32 LED matrix has 256 LEDs (Light Emitting Diodes) which are arranged in the form of a matrix with 8 rows and 32 columns. Hence it is named an 8×32 Dot Matrix LED.
Using the Parola and MAX72xx libraries we can generate different rolling LED patterns such as numbers, alphabets, scrolling text, symbols, emojis, etc. Apart from this, we can also display some sensor data like DHT11/DHT22 on this display. Let’s see some examples in this video.

thanks for this amazing tutorial.
Just a tip. If you want to loop temperature and humidity, instead to be stuck in humidity animation, just reset the display counter adding these lines:
....
P.displayReset(0); // Rest zone zero
}
if (display >= 3) {
display = 0;
}
}

Wow nice sir

I'm getting NAN 'c output. where did I go wrong?

[@YouKnowMyName-jt3ql]

Simple question, how we can display static text without flashing of bespoke bitmaps?

Awesome 👍

Very nice❤

[@ilovegoatsecks]

by copying your code on the website (and as shown on this video several times) the code gets stuck on the last sensor reading of humidity - by which i see you are constantly hitting the reset button. i have tried many many different fixes but it still gets stuck. what is up with that? how to get the loop started again?
