Hex values:.There are a couple ways you can go on this project, build everything from scratch or leverage a kit version. I'll cover both methods in this Instructable. See here for a list of supported LED panels.

Making an Arduino animated frame with 256 RGB Leds!
If you have access to a laser cutter, use "super-pixel-svg-files. The panels used in this project are originally meant for large-scale building and scoreboard LED displays.
You'll find several kinds out there from Adafruit, Sparkfun, Ali Express, etc. Unfortunately while they make look the same, there does not seem to be any standard for LED matrix panels and each manufacturer can use a different chipset causing them to behave differently. So be sure and only use the verified and tested LED panels listed here. You'll find mounting holes on the back of the LED panels.
Unfortunately each manufacturer's mounting holes will be different so you'll need to make your own template. The pan head screws you will use will still cover up the larger hole so it won't be noticeable. Once you've got the LED panels mounted to the back piece of acrylic. Then add the hex stand-offs and attach the front panel acrylic pieces. It's up to you what color you go with on the front acrylic panels.
I used a frosted white acrylic front panel on the bottom and a translucent smoke front panel on the topic, this gives the LEDs enough diffusion while hiding the LEDs when the display is off.
Alternatively you can get away with just one front acrylic panel if you sand the translucent smoke acrylic panel with grit sand paper giving it a frosted effect.
If you have access to a laser cutter, use the SVG files from the previous step. So you'll just need to measure the mounting holes on your actual LED panels and then modify the CAD file mounting holes accordingly before you laser cut. To power the panels, you'll need to make your own custom cable. The LED panels take 5V and you'll want a power supply rated at 4A per panel so that's 16A in total so get a 20A to be on the safe side.
The apps for this project are free and come included with some fantastic pixel art that was commissioned just for this project that you see here. You can find some really nice pixel art in 64x64 resolution on sites like pixeljoint. Tumblr has some great pixel art too. Of course, you can also make your own art.
Still images should be in. There are a few nuances to working with the LEDs, the main one being low contrast colors don't look good on the LEDs as the brightness of the LEDs tends to wash everything out. Here's a content guide with some tips for creating art for the LEDs. Apps are available for this project for Android recommended and Raspberry Pi.
The best app experience is Android which offers the most functionality. There are three main Android apps, one for pixel art designs you can add your own tooone for scrolling text including phone text messagesand a pixel art editor to create your own designs. PIXEL has two modes: interactive and stand alone. In stand alone mode, an animation or still image is written to PIXEL's onboard SD card and then the animation will loop with no connected device required.
Long tap from the Android app to write an animation or still image to the local SD card. Raspberry Pi users can connect via USB.Most of the time I just make stuf, because I like it, but this time I taught maybe it can be really functional.
First of all, you can use it as an beautiful decoration piece almost art :secondly, you can use it as an dimmable light source for your vid's. Did you use this instructable in your classroom?

You need some tools, but if you are like me an enthusiastic DIY'er, you will have them arround. You can start out of every corner; as long as you follow the S- patern see picture I started in the upper left corner note; code will be different later on, but still solvable.
After you put the mdf together, you start glueing your leds and start soldering all the components like the schematic. Note: I see that I forgot to draw the resistor in the schematic, this one ohm resistor must be placed between the digital pin on the arduino nano and the input of the first led of the matrix.
I've made some holes for the arduino nano, potentiometer and switch in the upper left corner of the matrix side panels. On the arduino I've used pin D9 for the leds but schematic says 8? First the simpel code always the same, cause we are gonne you the serial connection over usb. Especially for you guy's the one's that read the whole instructable; I upped a file named Spooky. Question 17 days ago. I use Jinx 2. Baudrate in INO und jinx must be the Same.
Answer 17 days ago. What I understand: You did upload the correct Ino file for Jinx to your arduino to work. You made sure that the baudrate is correct. You installed Jinx and got it to run on your pc. You connected the arduino with a usb cable to your pc and found the correct COM port in Jinx. You changed the correct setting ins Jinx meaning you chose the correct pixel layout, size of the latrix and baudrate. You powered your arduino externally and keeped it connected to the pc.
You started the output and chose one of the features to display. This should work. Do the leds show anything at all? Do you find your arduino in Jinx?
Maybe other type of leds?If you feel that my videos are helping and you would like to contribute, you can toss some coins in the Tip Jar via PayPal. I was worried that using Flash memory might be too slow, but it worked just fine.
You also need to create some sort of grid to isolate the LEDs from one another, I used my Laser Cutter to create the grid but you could also find something that works at the hardware store. One example would be to use a suspended ceiling light grid. You can see this in the code when I create the array and when I read from it.
Each character has 2 array or frames to create a simple animation for each one. Of course you can create as many as you want as long as you have Flash memory available. As always for more information about the tutorial and explanation of the code please watch our tutorial video. I thought you might be interested in an app I made for iPad.
It imports pictures and converts them to rgb hex code for use with neomatrix libraries It also works with esp and allows you to send the picture to the esp over WiFi from the app The app is free and called pixel on the app store. Wonderful project looking forward to building one. How hard would it be to store and read the arrays from an sd card? You could have a Mario card, pac-man card etc. Outputs are connected to Outputs and Inputs are connected to Inputs.
So which is it…are the direction arrows wrong or is the wiring wrong. Great Project. What do you think?Arduino 16x16 WS2812B RGB Matrix Animation Picture Frame - Tutorial
Hope this is what you meant by your questions? Hope that helps! One other great hack I discovered while building this: I did not cut up my 5M LED strip into pieces and use connectors.
If you bend it at each turn, it takes up two LEDs wasted on each turn. There are 15 turns, which uses up 30 LEDs. Then there are about 8 or so left over at the end. Then you can plug into both connectors built into the ends of the strip no soldering or cutting wires.
And you do not need those plastic connectors.
I found some connectors that worked fine, but there are many that do not work well. To compensate for the extra LEDs in the strip, I just wrote a quick translation program that takes the incoming sprite and ignores the LEDs in the turns.
It is lightning fast and works great! Had to share because it is MUCH easier than the connectors! Thanks for a great tutorial! Would there be a conceivable way to maybe link the display to say an IR Proximity sensor so that when I am close to it, the character changes to show maybe the date or the time? Thanks in advance. This has been a really fun project and I am definitely learning a lot. I have been making my own graphics and got to the point where I wanted to make a scrolling text.
Sooo I did it the hard way and just put a bunch of single files at faster refresh rate to make an animation of scrolling text. My text is simple and is 64 frames big. I just put the code for each picture after the other in order I wanted them to run, but the code runs from the bottom of my script.Actually, I just wanted to get some practice in coding user-controls.
I started playing with Rectangles and Brushes and Pens in the onPaint method until I got the idea to set up my own dot-matrix control. A dot-matrix is used to display text and signs in dot-matrix style like LC displays do. As a spin-off product of this matrix, I got an editor to build a char-set for the matrix.
The dot-matrix is built by 16 rows, each containing 16 dots. To be more precise, 16x16 rectangles. Each rectangle might be filled completely or just with circle shape.
As I needed at least some properties for each of the dots rectanglesI started with my own rectangle -class. Let's call it RectangleXT. Having this done, I could start building the matrix. Well, there are quite some things done in the onPaint method.
There are some properties of the rectangles we have to deal with. With an array of 16 integer values, we're now able to define all 16 rows of the matrix.
This is done with:. But how about some more letters? OK, take some piece of paper and a pen and start calculating letter " B ". Way too much work, you say? You're right. I wouldn't have it done this way either.
That's why I implemented the ' TeachMode '. In the demo app, you can enable TeachMode with a checkbox.
In TeachModeyou can click on the dots in the Matrix to get them enabled or disabled.Did you use this instructable in your classroom?

Reply 4 years ago. Any chance of adding a "play animation" option that plays all the frames in your browser so that you can check how it looks animated i. Reply 2 years ago.
Reply 4 years ago on Introduction. Great project! But it gives a solution for only one matrix What about a cascade of 16 units? Question 2 months ago on Step 2. My version flags it as missing when I do the code verification. Answer 2 months ago. Reply 2 months ago. Thanks for the link. Too bad it wasn't included in the original article. I am using a Neopixel 8x8 array to display characters for a toy project for a friend, so this will be very helpful in generating the proper code as I create the designs to display.
You are right. I've just added the link. Years ago it was a pretty popular and well-known library, even for beginners. Hello, thanks for sharing this editor - the pupils really like programming their leds! Keep up the good work! An animated view of the frames would also be really useful like in Piskel for instance. Any chance that this will be available at some point? Hi, this weekend's I had a bit of time and I've added ability to animate matrices, and added colors selector.
Thanks my friend, your work on the animation feature is very much appreciated - it's really useful. Hello, I saw that you had proposed a version 8 bits. Is this still planned? This would be compatible with all versions of Arduino. It would be perfect for us. But I do not know if you have the opportunity to do that. In any case thank you to you. If you want, I'll add the option to represent every image as a 8-byte array so the both forms will be available.
By xantorohara Software RnD Follow. There are some ways how to store this kind of matrix in the Arduino code.We used it to illustrate some of the famous emergent structures in Conway's Game of Life as well as to demonstrate the evolution of randomly seeded colonies.
The display now graces our Makerspace as a permanent art installation and we will continue to find creative uses for it as a general purpose large-pixel display. I decided to write it up as an instructable to document the electronics, firmware, and construction process.

Led Matrix 16x16
Unlike many LED matrix displays you might find out there, this one is not multiplexed. Each LED is driven by it's own dedicated control signal.
Sixteen of these boards provide the current sinks needed to drive the display. In summary, for our 16 x 16 display, we used one of these boards per row of LEDs and chained them all together to drive all displays. There are two aspects to the firmware. The first is how to render arbitrary images on the display. The second is how to render the Game of Life on the display. All the Arduino software that we used is up on Git-Hub here. The sketch there shows how to do both aspects monolithically, but it could be broken into an Arduino library with a bit of effort.
Most of the sketch is maintaining the state and applying the rules for Conway's Game of Life. There's some fanciness there associated with bit-packing, pixel-addressing, and sharing the display buffer with the game logic, but actually setting what is displayed is straightforward.
The display is represented in memory as an array of sixteen bit words.
Each element of the array represents one row of LEDs because that's how we wired it! To change the image being displayed the words in the array are shifted out one bit at a time in the statement "sr. This routine clocks in all the bits then toggles the latch pin to enable the desired outputs across all the chips at once to keep things stable. Two things to note that we want to play with. Rendering animations including shading should be possible by interfacing to a computer or by generating frames algorithmically.
We figure 4-bit gray scale at 30 Hz refresh is plausible back-of-the-envelope. The building of the matrix was a labor of love. A flat sheet plywood was cut to 3 feet square to provide the structural support for the display. Holes were drilled with a forstner bit at regular intervals for the LEDs to be mounted.
We chose to recess the ping pong balls slightly to avoid light leakage around the edges and disguise any irregularity to the cut edge. The forstner bit drills a hole for the LED to poke through the plywood while also carving out a round recession. Hundreds of ping pong balls were painstakingly cut in half to be used as translucent diffusion covers for the LEDs.
We found that making an initial slice with a utility knife and finishing the cut around the ping pong ball with scissors was the fastest and safest method.
