Arduino WS2812B 32x8 RGB LED flexible matrix test

[@Sir-Dexter]

nice

[@squirralien1863]

Just wondering if that software has a completely random pattern like individual LED's like you might see in a movie for a super computer, random individual LED's with maybe 30-50% on at a time.?? if you understand what I am looking for.

[@lascoytbg]

All individual LEDs are accesible in a seqential or random fashion by their index number. You don’t even need special software to address them, but I can recommend Adafruit’s excellent NeoPixel Arduino library /very easy to use/ or the more sofisticated one as FastLED.

is it possible to make a custom matrix shape? like a triangle?

[@lascoytbg]

Well, I didn't try it but probably yes. The WS2812 addressing in serial, so I guess you can arrange them in whatewer shape you like. You can by indivdual chips for under 20 cents and with some soldering skills it should be possible!

Where do you get your glediator software Sir? 🙂

[@lascoytbg]

You can download it, for example from here: ledpixeltm.blogspot.com/2021/04/glediator-led-software.html

Blog already deleted, u have any replacement link?🙏

[@laurengraham2698]

whar are the wires called? Ive been searching for them everywhere..

[@lascoytbg]

These are called ‘bread-board jumper wires’. In this project I used 3 male-male ones. You can find them everywhere, here’s a link to some cheap ones: uk.banggood.com/65pcs-Male-To-Male-Breadboard-Wires-Jumper-Cable-Dupont-Wire-Bread-Board-Wires-p-91799.html

can you flash a video or a picture on it?

[@lascoytbg]

In the video I'm using Glediator software as a frontend to drive the matrix. It can load animated GIFs and static pictures and also have a lot of build-in effects. It uses FastLED library to drive the matrix so the performance is dependant on Arduino board used and the speed of serial interface. In theory you shold be able to feed video, in my test the host software achieved 21-25 fps.

[@HassanDigitalLight]

Which Software ???

[@lascoytbg]

The demo utilizes the excellent Glediator software: www.ledpixeltm.com/2021/04/glediator-led-software.html

@@lascoytbg which Controller Use this Software

[@lascoytbg]

@@HassanDigitalLight it uses simple serial communication. In this demo "the controller" is an Arduino UNO connected to USB port with simple sketch uploaded on it.

hello sir can i ask why is my port not detected in gladiator

[@lascoytbg]

It depends! First of all you need to upload to your Arduino the WS2812 pixel converter sketch which communicates with Glediator. Is the Arduino IDE detecting your port? If not you may need an USB driver for your board. The IDE installation should have one out of the box, but if the board is a cheap Chinese clone you may need special one (in most cases they use CH341 chip but you never know). The Arduino software also communicates at very high speed with serial port so it's advised to use USB2.0 at least. Hope that will help!

i have the same leds a as your 8x32 ?????6 Help

What kind of help do you need? :)
