Creating PIXEL ART with WLED!!

In this video I show you how to create a pixel art display powered by Home Assistant. I hope you enjoyed this project! #WLED #pixelart has been one of the more fun projects I've worked on for this channel... It pairs great with #HomeAssistant!

Hey Kid, love seeing people of your age talking like this, and doing things like this ... respect. From a (49yr old Technical IT Director).

[jeffreyhaines]

Wow you make this stuff so approachable for an old fart like me! Really appreciate your reassurance for flashing

Great video, just built my 16 x 16 matrix after finally getting a 3D printer!

Just getting around to this project and when I slice the grid for the LEDs it is putting a solid panel on one side. Am I missing something?

[SnoWakeFPV]

Like Ian below - this project represents an intersection of three hobbies (obsessions): Individually-addressable LEDs, WLED, 3D printing... AND HomeAssistant! I've posted my make on Thingiverse, and may record a short video to show some of the finished results. Thanks for both the design, and the inspiration! Now off to print/build the 32x8... the parts just arrived yesterday.

Bro. Get a decent soldering station, solder and flux. Makes a world of difference

[karolisc]

Did this a while ago using esphome leds as display component and changing image position according to number input. Nice thing was that it's not some obscure numbers array, but real sprite picture with all images you can see and edit visually

[funkycraft]

You can also do this with a wemos d1 mini you can get about 3 for the price of the nodemcu, They already come pinless so you can just solder on, and they are about 2/3 the size.

Aaron love your video style! keep it up! Very beginner friendly

Nice Pixel Art. One question I had, can you not just create presets in WLED using the same JSON pasted into the preset"s API dialog box for each piece of artwork? In Home Assistant, you could just invoke the artwork using the preset name. In WLED, you can select a preset for WLED to go to as a default once power is restored to the NodeMCU. Using this method would allow you to change images using the WLED app or home assistant. Something to think about. Thanks for the video.

If all I have is an iPhone, what’s my best way to power and control 360 pixels of ws2812b with the wled app???

Could this same idea be used to create QR codes. Like create a QR code with the limitations of the LED matrix and then upload that to the service that supports the QR code links or in the reverse?

I wanted to try to recreate this functionality using Google Sheets, since I don't have excel. I think you may have a misconfiguration in your panel, since when the output from your sheet is sent to my panel, it doesn't render properly unless I reset the panel settings. I found out by sending a command to just illuminate the top left 4 pixels, and when misconfigured, it lights up the top right first row, and the top left second row.

Is there any way you would be willing to share a copy of the excel sheet without any macros? I cannot import the grid of examples into Google, so I manually recreated a couple, but you've got some great artwork that I would love to send to my panel!

Finally, the way I built my panel, I used a sheet of white shelf liner vinyl that I bought at a dollar store for the diffuser. I printed some grids to separate the pixels, and the vinyl gives a nice consistent diffuse glow without any lines from a 3d print.

Wow just found this channel today.

Amazing LED videos, looking forward to start playing with my LED's

I got the same matrix you linked. Once I set up the 2D Matrix in WLED, in order for the order to be correct for the effects (like having the scrolling text look correct), I had to set the Panel start (at the bottom of the 2D Matrix setup page) to "Top" and "Right" (default is left) and serpentine. This completely borked the pixel art presets. Have you seen the same thing on your panels? I'm going through the Excel file trying to reverse-engineer how to get the pixels back in the right place.

I had to invert all the odd rows (so they go 15 to 0). But now I'm trying to figure out how to make it build sections of the same color correctly. So like if I have the first pixel in two rows the same color, that's now pixel 15 and 16, not 0 and 16, and that makes the code do weird things. Still chewing on this...

Is it possible to build this somehow battery powered with usb-c loading function? What kind of components would I need? 😀

[jarrod]

I'm not very electrical savy but would it be possible to solder together individual neopixels or something similar to use less power? You said 15A which just seems like a lot of power for LEDs. Or is the high current amount juat because there are so many LEDs?

[Gareth.W]

Great video! I received a 3D printer for Xmas and this is exactly the sort of thing in looking forward to trying out. Thanks for sharing.

[paulcabrelli]

Hi I found your video very interesting and I was following your example for switching on pixels with red and blue (15:41 time on video) Should it be 0, 7, [255, 0, 0] for the red pixels then the two unlit and then 10, 17[0, 0, 255] for the blue pixels?

[MarkGhali]

got my 32x32 matrix going. Looking for the 3d printer files for the grid for the pixels. Thank you Aaron
