HOW TO Make Your Own Scrolling Text LED Sign (arduino+ws2812b LED's)

[@kckunkun]

Thank you so much for the "monitor resolution not fully filling up the screen! RESOLVED! (27" samsung curved) " video! Had no idea how to fix my mon and your solution was perfect

Any idea how to get this to work with more than 7 rows? I have a 10-row matrix but the text only dispalys on the top 7. There is no physical issue with my wiring etc.

[@cchivers1983]

Go to 5:40, he’s set his to 7 as he has 7 rows (strips). Hope this helps

[@DRCE777]

Hey I followed your tutorial and it works great. Thank you very much! I want to show a heart symbol, but it turns out as garbled text, can anyone help me? 😊

[@kld9968]

Hi there, it's wonderful, works perfectly..is it possible to increase frame rate..thanks for all.

[@Systematic_Sean]

How can I make the text larger? I'm on a 16x16 matrix, the text is scrolling but only takes up 7 pixels in height

[@cchivers1983]

Go to 5:40 the answer is there, he sets his row to 7 as he has 7 strips.

[@DRCE777]

I want WiFi support for this, Using NodeMCU esp8266, where you can change the text and colors on the fly. Is that Possible? I've already done the wiring but instead of using Arduino nano, I useed esp8266. Now all I need is to find out how to do the WiFi support.

[@danman32]

I'm looking for that too. WLED supports a matrix now with ESP32, but from what I can tell, only for 2D effects. It has an API that could be leveraged to feed text, graphics and other items. Dave Plummer of Dave's Garage has Night Driver that is powerful but complex.

Hello you could make a video of how to record the message on an SD card and then extract the message with an Arduino from the card and take it to the matrix

Can we make a clock?

[@lulam.5844]

has anybody tried with redboard and find any differences? i am hoping to use what i have and just wanted to see if anybody had tried

[@VE3DAL]

Awesome vid bro! thank you.

[@denn450]

could I connect to 5volt phone usb and keep it that way to show my display and leave it like that for couple hours

[@MoVoltageMoPower]

although these chips require 5v, you have to also make sure you can supply it with enough current... a phone 5v adapter usually only spplies 1 amp... which most likely will not keep more than 10-20 led's on at the same time

[@ernestorivero9909]

Hola podría hacer usted un vídeo de como grabar el mensaje en una tarjeta SD y después extraer el mensaje con un Arduino de la tarjeta y llevarlo a la matrix

how to change text color to rainbow sir?

try random()

bingung saya itu gimana bisa disebut aqualizer...decirasi lampu cocoknya...

[@alfonsocino5434]

Hello, beautiful project! I followed your tutorial step by step and everything works perfectly. I have only one question: is it possible to increase the number of characters? Currently I only see 17, if I write a longer text, it is truncated. Thank you

[@vaughnscott511]

In the line of code where the loop says if --x is < -70 , is where the matrix controls the ending of the scroll. The length of the message, and the width of your matrix need to be taken in account during the scrolling. You need to imagine all the text leaving the screen as passing a duplicate screen, of the same width to return to the screen again. You could set a variable for 'scroll length', that is the size of the length of text, spaces included; and 2x the size of the width of your matrix. this will give your loop enough time to complete scrolling, before it starts again.

Awesome video - thanks - Is there a setting to allow 48 leds across x 16 down.using uno I’m only getting 32 x 16 but showing only 32 x 8

[@SaleemMukhtiar32]

can I use arduino uno instead nano

[@DaDom07]

Sure, why not?

Hi bro, can i get coding

now inteface wit HC05 to edit display with smartphone

[@vaughnscott511]

Here's a little something I threw together for bluetooth using and esp32. Its easy to change for an hc05, you just have to identify your tx and rx pins and add them into the define area on top.

[@vaughnscott511]

forgot this: matrix.show(); right above delay

[@fredmunyao787]

@@vaughnscott511 thanks for the reply, can I get your contact please

Pixels, not bits. Each letter is 5 pixels wide plus one pixel column between letters. Each pixels is 24 bits so each letter is 120 bits wide, plus 24 bits for the space between letters.

[@jstro-hobbytech]

Some zoom when showing the code would've helped

[@Tigs62]

Most definitely. I was thinking the exact same thing.

[@localnews2302]

Hi sir thks for the video can u sent me the code pls

[@ernestorivero9909]

El código está en el ejemplo de la librería neomatrix que dice MATRITEX creo

[@bagaskeco1876]

make a tutorial using 4 dong sis

[@hellboy6558]

Could you make a face mask with this concept? mask shows smile and words like we talk.... And it should be controlled by our phone

[@MoVoltageMoPower]

Hell Boy most def could... requires much more detailed coding which is why I went electrical than computer engineering 😅🤣 sorry
