It's not hard but took me two days to find a useful tutorial. Thank you for your clear explanation. This project adds a little more flavor to this Christmas.

Thanks for the tutorial! This got me up and running with an Arduino Mega2560 and a WESIRI 8x32 LED Matrix 256 Pixels WS2812B. I had to configure my matrix flags a bit differently than what was shown -- just kept NEO_MATRIX_COLUMNS in place -- but that was it.

Great tutorial, very helpful, a joy to watch, please keep it up, many many thanks...Steve H (UK)

Many thanks to you for this very clear explained tutorial! Now it works and I can put any text to scroll via Arduino on the LED matrix. 😊👍

Hi, great, just what i was looking for. I would like the scrolling to stop when thr letter H reach the left led collum, erase the entire text and star a new scrool from the right, do you think it is possible

How to use it as a LCD? I want to display "temperature and humidity" variables on it as on usual LCD1602. Can you recommend any libraries for doing it easy?

Great thing done sir, can you please provide the link for code you made for your project

Hi If I have an array of 16 x 192. How do I physically connect the WS2812 8 x 32 boards? =) i mean the line diagram....

Hi please the arduino neo matrix library could support 3 of 32x8 matrix on serial ?

Do I need a resistor to stop it from shorting? I see you connected 5v to something other than the one on the Arduino, is it possible to use the 5v on the Arduino with the resistor? Or will I need a battery pack or something.

Hi! I am new on this and a little help would be good. I heard you said that 15A is needed for all the led to display but 2A is okay for a Text display? What Adapter are you recommending? thanks

it's possible to stop the scrolling and print variable values?

Do you know how to get other fonts working with this code? Thanks

Does anyone know how can I set the text to be static not scrolling?

Can u make a video how to make arduino clock using this 32x8 rgb matrix? I didnt find any video like this in youtube

Great Video! Is it possible to flip the matrix so the text is scrolling in the other direction? (Up to down instead of right to left) How in that case?

Hi there, this is pretty cool. But I was looking for a way to have the letters static instead of scrolling. I want to learn how to scroll writing left to right, right to left, as well as top and bottom. But more importantly, how to get letters and numbers to fade in/out of each other. For example, a countdown from 10 to 1 fade out and in over each other. Is there a way to do this? Thanks.

Just curious, would you be able to cut it up to a smaller size and it would still work?

@ReidProjects

Unfortunately not. That said, there is smaller matrixes (8x8, 8x16) and if you need a different format, you can always take a ws2812b LED strip and wire your own matrix. Hope it helps !

if(--x x = matrix.width(); if(++pass >= 3) pass = 0; matrix.setTextColor(colors[pass]); } when I changed the number in the first line I was able to get a longer line to print, but I don't know why. anybody know why?

Can I import the matrix library and use it for a 32x8 neopixel setup?

I like your project and I would like to make a similar one to use it for our Senior Center Dances. To display "LET"S KEEP DANCING" or any other similar message. The LED matrix you used is not available and I wonder if I could one for sale at Amazon made by BTF-LIGHTNING> "BTF-LIGHTING WS2812B RGB 5050SMD Individually Addressable Digital 8x32 256 Pixels LED Matrix Panel Flexible FPCB Full Color Works with K-1000C,SP107E,etc Controllers Image Video Text Display DC5V" Do you think it will work? I have an Arduino Duemilanove. It is like an Arduino UNO. I hope it works. I might like to attach two matrices later. But I think I will need to buy a power supply with more watts. Thank you.

I am so frustrated because I bought one of these, no instructions manual whatsoever... I don't know why do I have a main 2-wire pair for power at the center, and 2 more + and ground cables near the data in and the data out wires... your video is the only thing I could find as a reliable reference... *But the way you connect the wires... there's something weird about it...* you use the "3-wire data in wire group"... 5V to the outer power source... it makes sense... but why the GND to the arduino then? Can the Arduino's GND PIN actually handle up to 15A?? I have literally wasted an entire hour trying to figure out all the technical details I need about the wires available in this matrix

This font is rubbish. Is there a way to change it?

My matrix is only lighting up the top two lines, not the whole matrix.

I tried to do this but I can't load the sketch on arduino. The ide gives me an error, but It's not about the sketch. Can you help me please?
