- In this video, I build an interactive LED wall display using an Arduino and 3D printed parts!
This project was largely inspired by Nanoleaf tiles. I just wanted something more affordable and interactive.
Here’s a link to the code: github.com/mrme88/Interactive...
Here's a link to the 3D print STLs: www.thingiverse.com/thing:408...

Great vid man! I have no experience with arduino but want to learn it. Is this a good first project? Obviously it would be a smaller simpler version of this.
I don’t want to discourage you but this is an awful first project. I helped my 12 year old brother build a smaller version of this for his science fair and he doesn’t want to touch arduino again lol. I would highly recommend getting an arduino starter kit off amazon and looking up some easy tutorials for the kit first. Once you have a couple easy ones under your belt this project will seem much more manageable. Hope that helps!
This is a fantastic project! But not for beginners. I recommend looking up Paul McWhorter Arduino tutorials (the newer playlist). I've been learning over the past couple weeks and I'm almost to a point where I could control this. Almost.
Keep it up! Hopefully these bigger projects won’t seem that bad soon
@@TheTechRandom it really seems okay!! That's why I showed up here! I'm saving this video for later so when I'm a bit more used to it I can give it a shot :) maybe a bit smaller the first time though.. this is a pretty big job!
You did amazing btw, I love this type of CZcams
I'm so distracted by the Mr clean poster
It’s the GAA Galway flag that got me. Up the Dubs!
lol
Dude Chris congrats on this project! i work on a lot of project myself and I know the feeling of after all the hard work and finally seeing everything function as designed. Good job and keep posting!
Cool led wall tile panel. Love hot you press on the tiles to make them light up and change colors. Awesome.
Thanks for checking out my first video! Let me know if there’s anything you like or want me to change for the next one!
you could make into a really big launchpad (like the sound devices)
I actually used it for something like that for a school project a few months ago lol
Would you do a dance floor like this?
That’s something I have planned! Only problem is cost 🙃
@@TheTechRandom
I here you on that.. well can't wait to see more from you keep up the awesome work 🙂
Great result for a lot of Effort. Looks brilliant.
Great idea and lovely execution, for the button grid stripping an old network cable gives you a lot of small guage cables, it works out cheaper in the long run.
Such a cool video, Chris!! Can't wait to see more!
Thank so much for the support!
The matrix solution for the buttons was really clever, I’m not sure I would have thought of that myself. Really great work man!
Thanks! Problem solving is what makes engineering fun!
Very cool project.I looked at it in one breath!
Thats awesome man! Iv been dabbling in Raspberry pi projects, this has given me a bit more inspiration!
Awesome work!
Can't wait for more videos!
Just a thought for your v2... Mechanical keyboard switches. Easier to press and your panels can mount directly to them like a giant keycaps. Also. You could swap in a .8mm nozle double your line width and print in case mode to save time. You'd have to attach the button stems after, tho.
I'm very impressed. Great projects and great videos.
Amazing idea. Mechanical keyboard buttons are also way more satisfying to press. I’ll definitely try and include this in the next version
Watched from start to finish, great build mate, fav video, nice narration, must have taken you ages in post production, build and video editing. A really great job mate
Thanks for the support! This was my first video so I put more time into it than I probably should have haha. I’m very happy with how everything turned out though
This is the coolest thing I've seen today!!🤯
Great work, keep it up!
I was expecting to be frustrated with another rehash project of the same light panel video Ive seen a dozen times before this - BUT WOW!
This was awesome! It's beautiful, fun and original!
I'm really impressed by this and happy you posted it.
Thank you!
Glad you liked it! Be sure to subscribe if you want to see the bigger LED wall I’m working on right now
@@TheTechRandom NO
TOO POWERFUL
@@TheTechRandom i have never done anything big or 3d printed anything, but i have a couple suggestions for the bigger wall
1. find a way to dissipate the leds more evenly/have more leds per tile
2. round the edges of each tile so that the seams between each tile aren't as obvious
This is AMAZING!
Excellent work.
Congratulations Dude that is a awesome job and that’s coming from a old man wish I knew how to code still trying to learn!Keep on Going!!
I can tell this took a lottt of work, it looks awesome! cool idea & great job!!
Thanks for the support!
Wow! That’s cool!
For the first video is it perfect. It is so much better than my videos right now!
yo dude this is amazing, thanks for sharing!
Glad you liked it. Stay tuned for more!
Really great project! Would love to see an animation kinda like a water droplet expanding outward from a tile when pressed... Maybe a switch to control what mode you're running. Absolutely love the project though!
In the newest version of the wall I added a menu screen. A pond effect would be super cool though, thanks for the idea!
This is awesome!
Good job!
Muy genial! Está excelente
man now i want a 3d printer more than ever. amazing wall display.
Thanks. You can get a good printer pretty cheap these days. Do some research to figure out what you want then look out for sales. I got mine for less than $200 and I use it all the time!
Brilliant, how about playing a sound/note when each button is pressed?
Great idea for a future update. I’m actually working on an electronic music box in my design class and I have plans to connect the two in the future, essentially turning this into a giant MIDI board.
Or have the lights dance to music
This is something I’ve been working on for a while actually
Great first project, not the easiest one, i have to admit. Keep up the good work, liked the timelapse. You got a sub.
Well first video haha. I’ve been working with arduino for a few years
Small suggestion: For interactive editing, you cycle through several colors for each tile. I suggest that after choosing a color on a tile, the first press on another tile will change to the same color (then step forward from that point in the cycle if there are multiple presses). So you can select a given color on any tile, then replicate that color with one press per tile.
I am very happy to see what was behind the Snapchat content. Keep it up.
Nice work!
Thanks, glad you like the project!
Amazing project. Watching this has inspired me to finally buy an Arduino starter kit to try and learn how to make these kind of things. There's a similar type of project to this that I've had on my mind for years that I've been wanting to build but had no idea how to do the technical/electrical side of it, and I think I could use a lot of what you've done here. I'm assuming there's a way, but is it possible to also somehow hook up a speaker and have a sound effect play for each button when they're activated?
So glad I inspired you! Yes it’s possible to connect a speaker. The arduino mega has two Digital analog converters specifically for that. It’s a bit more advanced but there are plenty of tutorials on speakers with arduino. Engineering is pretty much taking a bunch of tutorials for separate things and combining them together. When you approach a problem with that mindset it makes it a lot less overwhelming. Good luck!
OMG Bro It Looks soooo coool
Thanks! New project coming tomorrow 👀
Found on Thingiverse when deciding on some LED projects to print... and I am blown away.
Glad you like the project!
Bro Awesome Video. So help full
You are my favourite tech diy youtuber
Thanks so much for the support
dude thank you for this going to do this forsure
Good luck!!
Nice work! I was curious to see how you aligned each 3D printed square and your technique worked well! I also have built an LED wall which can be controlled via bluetooth and an iPhone App I developed
Glad you enjoyed! Phone control is definitely a feature I want to add in the future.
@@TheTechRandom When I've been doing phone control I've used an app called RemoteXY. It gives you the option to create your own GUI on a web page with as many controls as you want to fill a screen with. The only down side to phone controls I've found with RemoteXY is having to pair your module with your platform. Androids use an HC-05 Bluetooth module and iCrap (yeah, I said that) uses an HM-10 BLE module.
Thanks for the tip!
great job
Great Video your very professional sounding.
I would totally buy one of these.
Maybe you could do a fallow up video with pricing and the pros and cons.
It would be pretty quick to follow the first part of the tutorial and get the stl file and get a cost estimate from shapeways or another print on demand website. This would be the cheapest way if you don’t want to fork out the cash for a 3D printer
Good job. 👍👍👍👍😃😃😃
Hi Chris, awesome video man! Hope your channel is a success. Just wondering if you used a power supply to power the LEDs directly? Seems like a lot of current to be drawing from the Arduino. May have missed it in the video. Cheers
I do have the power going directly to the LEDs at two different points for even current distribution
@@TheTechRandom Ah sweet. Thanks for the quick reply. Nice of you to give your little brother a go haha.
Amazing!
All I was thinking watching this was - "Proximity sensors", good job
Physical buttons are a lot easier to work with lol
A lot more cheaper also.
Thanks for the post, I have planned on making a coffee table in September with a similar issue 64 analog inputs to an arduino, but chose to go a different route and instead of the matrix setup am using a few multiplexers. Haven’t used them before so I’m hoping that works
Good luck! Multiplexers were my original plan but I switched to try and cut costs
I feel like only engineers enjoy the trial and error of long, diligent projects like this 😂 but it looks amazing man! Thanks for the video and for the links as well
No pain, no gain 😂
Nice job. Only thing I could see doing different is adding extrusion panels to diffuse the light more evenly.
The individual lights don’t shine as bright in person as they do on camera. These videos are recorded on my phone so the lights create hot spots. To the human eye the light is diffused very evenly!
hola queria saber donde van conectados los cables verdes y amarillos en arduino porque me ha gustado el proyecto y no encuentro la posicion exacta a ellos gracias y muy buen trabajo ^^
hello absolutely love this project and im working on a similar project. How would you change the code from the group of six relative LED's to two relative LED's (only one on the right and one on the left)? I'm also having problems with which rows and columns go into the relative arduino pins. Many thanks!
Pretty cool but quite an undertaking, good video keep it up. Which 3D printer are you using?
I use the Anycubic i3 Mega. Great printer for the price and I’ve never had a problem with it that wasn’t user error haha. If you’re interested there’s a link to it in the description.
pretty cool.
Love the idea of the haptic input. It's a refreshing difference to all the WiFi solutions. But I wouldn't have left WiFi out (ESP8266 or now in 2021 an ESP32)
Check out my led lamp project using the esp8266. The v2 I’m working on also uses a matrix of these boards for more control!
This is cool, can you imagine a modular version!!
I’ve been trying to work it out for a while. I have some ideas but nothing practical yet. Stay tuned for when I figure it out though!
This is awesome. Much too advanced for me to learn. But was wondering if i did not want the feature to change the color by touching the panels but just want to build the wall panel like you show in the end with the LED in it, is that something we need Audrino for?
You would still need some way to control the LEDs and I believe arduino is the easiest way to do that. Getting the buttons to work was by far the hardest part of the project though so you could easily learn to do the code for just the LEDs by following some beginner tutorials for FastLED.
That's really cool, but i was wondering if on your website you could maybe release the 3d CAD model? thanks.
All the CAD models are on my thingiverse page linked in the description of the video and on my website!
awesome great video
13:00 It looks like you need some smoothing capacitors at each end and a loop to ground.
The difference in shade is actually caused by slight variation in the thickness of each tile from 3D printing. It’s only really noticeable on camera and you can’t even see the individual pixels in person. I record everything with an iPhone which are notorious for being very sensitive to light.
@@TheTechRandom oh okay. Though it still might be helpful to use some caps if you plan on doing a design or pattern with a lot of full brightness white squares.
Thanks for the suggestion!
Chris great video! You have inspired me to make something similar but not exact for my kids. My project is much smaller. I am creating 8 hexagon something like a nanoleaf. I want the rainbow effect and the push button effect. I don’t write code. But I did get a starter kit and have been working on small projects. Is there anyway you would be willing to help me take your code and make it work for my project?
I could try but I’m not sure it would work. Programming is a very iterative process and the hardest part of the code is the algorithm that tells the wall which LEDs to light with each button that’s pressed and it is entirely dependent on the way you build the tiles. I’m always willing to help though so you can email me and I’ll do my best (chparkertech@gmail)
Great job, looks awesome.
Thanks for the support!
Subscribed... this is quite beautiful, it also functions as a fancy chessboard!!
I wonder how much power it draws on full brightness! or when it runs an Arduino program
Full white at max brightness draws about 19.2 amps. I’m only using a 10 amp supply so I have to make sure my programs don’t draw more than that
If you are still monitoring this video I had a quick question. With the way the buttons are wired together are you able to push more than one button at once or would multiple button presses interfere with one another?
The hardware can still detect multiple button presses. I don’t use it in my code at all but I’m sure there are many uses for this feature!
this is amazing! just a quick question. is the code still use able when im not using the buttens?
The rainbow mode will work without buttons but the drawing mode won’t. It would be pretty easy to modify the code on my github to only do the rainbow effect though!
Do you have a timeframe for when the next version will come out? Curious to see what improvements you have in mind.
I’ve been working on a design that’s separate tiles that connect together magnetically. I have a pretty good idea for how I’m going to do it but it’s going to take some time. I have two videos I’m working on now and I’m trying to get one out by tomorrow but once both of these are done I’ll start on the new LED wall. Other features I want to try and include is a web interface that allows me to control the wall with a phone or maybe even my Alexa. Hope that’s enough information to get you excited. You can *probably* expect it to be out by spring but I need to stop making timeline promises while I’m in school 😂
@@TheTechRandom No rush. Always excited to see what you come up with! I plan on working on a similar project in the future, way in the future... I'm just starting out with Arduinos and need to get some experience before I tackle something like this. With the aid of the keypad library, is it possible to make a 16x16 board? I believe this would require 32 i/o pins for 16 rows and 16 columns. This would also require more LEDs than in the 8x8 board. Would probably do 4 LEDs per tile, with a total of 1024 LEDs vs 384 LEDs. Would this be too many for an Arduino to handle?
Totally doable. You’ll just need a power supply big enough to power all those lights. Looks like at max power that would draw about 50 amps so keep that in mind
It looks damn good bro...
One question.. CAN WE USE HAND SWEEP SENSOR INSTEAD OF THE SWITCH TO CHANGE THE COLOUR. IF YES THEN HOW???
I want to make is like neonleaf canvas, touch sensitive please give me a solution...
Sensors like that should work but they might need to be connected differently. The buttons I used work because they short two data pins. Sensors like that usually use analog values to tell when a hand is present so you would need 64 analog pins to make it work on this scale. If there is a touch sensor that works like a button the short two pins then you could use that the same way I built this. Check the data sheets and be ready to write the code for whatever you decide to use!
How many rolls of filament did you use. Hoping to just squeeze by with 1 roll but I don’t want to be cutting it close. Thanks a lot!!!
This took me 2.5 1kg rolls. I don’t think there’s a way to print 64 of these tiles with less than that
That's epic
Welcome to Hardware Unboxed
Does piezoelectric crystals work instead of buttons? It'll be more interesting that way to interact with the individual tiles?
Nobody:"...
Master Redstone:" create a tiles that uses a button"
Awesome video man! Subbed. Do you think you can share/explain a schematic diagram? I am gonna do something similar but without the buttons, every guide online only explains how to power like 50 LEDs but never hundreds like this project... thanks!
If you’re just doing the LEDs app you have to do is connect the 3 pads of each strip together. For your power supply, if you want all the lights to be able to shine at full white you’ll want enough amps to satisfy this equation: amps = #LEDs * 0.05. Just make sure you’re connecting the power at a couple different points on the strip and not just the first strip, otherwise some LEDs won’t be as bright.
@@TheTechRandom That's super helpful thank you!
What a nice project. what is the power consumption of this build?
With all the LEDs at max brightness set to white it’s about 96W. The rainbow mode, which is what I usually have it on, consumes about 50W
Still very cool
nice idea. When it works the arduino is always connected to the computer? instead of 3d printed tiles, what can be used?
The arduino doesn’t have to be connected to the computer after the code is flashed. It can be powered through the USB port or the Vin pin. If you don’t have a 3D printer you could buy large sheets of acrylic to cut squares out of. You’d have to find a new way to attach them to the board but it would look really clean if done right
Chris Parker Tech thanks you. I try in This quarantine days! When or better, if i finish, i show you the result! Many thanks man
Cool!!!
would i need to do all that wiring if i'm just doing the tiles without the buttons? so if i'm just running a programme from github
Nope. If you don’t want the buttons you can just wire up the LEDs and power them with 5V. The LEDs only took me about an hour to get working.
Can you build this for a backlight old LCD replacement? A full array backlight (like the apple display pro xdr)
This is a very cool project!!!
Have you ever thought about playing with the STM32 Blue Pill boards? They have more resources than an UNO at a fraction of the cost. the UNO has 32k flash and 2k RAM. The Blue Pill is 120k flash and 20k RAM. They also have a much smaller footprint, slightly larger than a Nano. You can get the Blue Pills out of China on Ebay for about $3. It is a bit of a learning curve when switching over, but these are great boards once you get used to the differences. There is a FastLED library branch on Github for them. To use FastLED you have to use the Roger Clark definitions for the board in the Arduino IDE.
The one coding improvement that stands out as a must for the project would be the way you select colors. Having several push and release standard colors is great and can be maintained. But if you were to make a push and hold function where the color cycles through a colorwheel function it would open up a range of colors you aren't getting with the push and release.
Honestly I could spinout on variants of your coding. But that is just my mind racing through possibilities! Really though it is a pretty nice piece of work!
Just skimmed through your code and saw you are using FastLED. I use that library regularly!
I’ll have to check these boards out, they sound really useful! The latest version of the code on my github has a better color selection but it’s still limited, I like your idea of a click and hold and I’ll look into that for my next version!
So this is a with a touch sensor for a switch, but pretty much:
void clrSel(){
int continuous = 1;
clrNo = 0;
lampOn = 1;
while(continuous == 1){
if (sensors[0]->read() < 35) {
continuous = 0;
pressed = 60;
}
allColor(Wheel(clrNo));
delay(20);
clrNo++;
}
}
CRGB Wheel(byte WheelPos) {
if(WheelPos < 85) {
return CRGB(WheelPos * 3, 255 - WheelPos * 3, 0);
}
else if(WheelPos < 170) {
WheelPos -= 85;
return CRGB(255 - WheelPos * 3, 0, WheelPos * 3);
}
else {
WheelPos -= 170;
return CRGB(0, WheelPos * 3, 255 - WheelPos * 3);
}
}
Very cool concept. Since you’re working with FastLED you could make this code a lot simpler by using HSV colors instead of RGB. Basically just have a number incrementing up to 85 while held and returning that value * 3. HSV also keeps the colors about the same brightness and gives better yellows
I'll have to look into that. I have so much code built around that that the shift would be immense!
Hey, what should i use to power my arduino when im using it for led strips in my stairs.
I would get a power supply that has a 5V output and supports 0.06A x (Number of LEDs)
How many panels can you print from the filament you have linked? (How much filament did you need for this project)
In total I used about 2.5 kg so I had to buy three rolls
Edit: Actually it may have been 1.5, you can check by dropping the .stl into your slicer and multiplying the estimated weight by 64
@@TheTechRandom I'm looking into buying one, so I'm pricing out how far the supplies go -- thank you for your answer!
Well worth the price of entry. I got my anycubic i3 mega for $250 and it’s served me well for almost two years now. Best printer for the price in my opinion
Very well done, but how did you come up the idea?
I saw a bunch of people making there own versions of nano leaf tiles and decided to try my own. I knew I wanted the tiles to be clickable and that I only wanted one arduino. I decided on the 8x8 grid because it had a lot of potential for games. From there it was just a lot of research and prototyping!
It would be cool to make a checkers game out of this
Dooooodddddd......How to you only have 1K subs......This should be up there!!!! Keep up the good work!!!
Thanks for the support! The channel is growing fast 👀
Is there a reason beyond style why you separate the leds like that? Curious why you don’t squeeze them together tighter.
It was a cost saving measure. I was a broke college student at the time
@@TheTechRandom good to know thanks for answering!
Hi Chris Parker Tech i create a4 col and 3 rows for the button. How can i change the program? 8X15 stripe led. Thanks!!
Check my channel, I have a second video that goes over how I wrote the code. In that video I describe the algorithm I use to light each tile and how it can be changed to work for different sizes
Have you created a Simon memory gas with this board?
I haven’t but that’s a great idea. Currently I have the modes shown in this video, tic tac toe, memory (the color matching one), and the filler game from game pigeon on iPhone.
that was a very nice project. looking forward for more videos from you. can you help me with this. do you know any websites from which i can get electronics for less price. anyway keep doing more projects like this. support from india.
Hi may i know what brand of led strips u used on the ceiling?
Same ones linked in the description. I used the 30 LEDs/meter variant
You should try to use acrylic panels instead of plastic, I think the light wo7ld diffuse better. But i could be wrong. Still looked dope though, I subbed
I’ve used acrylic on more recent projects!
Nice work brother,keep going ...
Now that winter term is over I’ll be uploading more frequently. Stay tuned!
How many hours to print all the boxes? Must have been over 60 hrs. I am guessing of course.
The total print time was close to 192 hours for the whole thing 😅
I was thinking of doing something similar but JUST the RGB leds alone would have cost over $250 for the size of panels and amount i wanted. it was going to be setup as an LED matrix. i've done the work before on a small scale. addressable strips would be a lot better price wise and everything.
The 5 meter strips I use are about $22 a piece. It would be cool to do a wall that big but the cost is definitely prohibitive lol
You should make a video together with Bitluni
I’d love that haha. Maybe I should try and message him 👀
this is so dope.. i wish I knew how to code
Not trying to peer pressure you but you should learn! I learned everything I needed to from 6 months of courses and you can find all kinds of free ones online. Code Academy is one that comes to mind. Pick one language to learn (I recommend C++) and once you understand for loops and if statements you’d be surprised how quickly you can start making stuff like this 😉
u deserve more subs and views :(
Thanks
Would u sell one already mailed !???? It dont have to be like that exactly if so ... lemme know
It would be very expensive to make and ship one since the parts aren’t easy to get right now and it took forever to make anyway. I’d recommend trying out the project yourself unless your willing to spend $2000
Omg I think I might actually try this.. how much do the addressable led's cost, and is a cheaper option gonna make it worse
The ones I used are the cheapest ones on amazon. It’s about $20 for 5 meters and this uses 2.5 rolls. There’s not much you can do to get around that part because they have to be addressable for this project to make sense
@@TheTechRandom oh, okay. Ill have to save up for these because I'd rather this tan spending like €500 on nanoleafs. Will you ever do a giveway on them by any chance 🤔
I’m definitely not going to be giving away a the wall just because it’s too big to ship. I’m planning on making a modular version (more like Nanoleaf) sometime in the next year so I’ll probably give away a few of the modular tiles when that happens!
Oh okay! Sounds good. Will look out for it. Thanks bro I love your videos.
Chris, is there a reason you used an Arduino Mega instead of an Arduino Uno?
Yes. In order to make the button matrix I needed at least 16 IO pins. The arduino uno only has 13
