How To Control WS2812B Individually Addressable LEDs using Arduino

[@JimFranklin63]

A very good introduction to the RGB addressable LEDS. I would say very useful for beginners and old hats like me. Well done. and well presented.

[@HowToMechatronics]

Thanks, I'm glad you found it useful!

I watched until 5:05, then wrote this comment and grabbed the LED strip so I can do cool visuals on wall art... Thank You!!

[@aaron4820]

Thanks for this! Got myself a pack of LED diodes which I thought was just a simple 4 pin RGB LED, which turned out to be a WS2811 8mm diode, was extremely confusing why it wasn't working when I followed other simple RGB led tutorials, and got to this which makes so much more sense! (and so much easier given I can control multiple of those diodes just by plugging them into a breadboard..!

[@Ultrasilverr]

very good introduction to the RGB addressable LEDS. Thank you

Hi Dejan , your LED projects are fascinating. It would be great if you could do an in-depth tutorial specifically on the hardware and then the coding needed for first an LED cube 8 x 8 x 8 and then the holy grail of all electronic hobbyist- The RGB LED CUBE , I think that tens of thousands of electronic enthusiast like myself would benefit from such an educational video- actually the subject matter is so complex in my opinion you would need several videos- maybe :-) Thank You So Much Jim

[@HowToMechatronics]

Thank you! Yeah, LED cubes are pretty cool, but I couldn't say if or when I would make one. Cheers! :)

[@wellofbeersheba]

I love these collaborations - really gives each of you more scope.

This is the LED Ive been looking for! I plan to switch out my LED as my old ones died out on my keyboard. Awesome video!

[@ishaankelkar7521]

Amazing amazing amazing video and unbelievably helpful. You are the best! Gained a like and a subscriber. Exactly what I was looking for and explained in absolutely PERFECT FASHION. THANK YOU SO MUCH!!!!!!!

[@rushabhnagda9267]

Thankyou for this detailed explaination

[@FrancescoCositore]

Great tutorial! Very useful!😉😉 just a note, in the project you should add some shift register in order to minimise the number of Arduino analog input so you will be able to use Arduino UNO board instead Arduino MEGA in the project.

[@johnrobinson1140]

or even a Nano, one 8 bit shift register would work

[@fringeanomaly9284]

How to do that ? Any guide for that?

[@spsnow7128]

Very informative. This is exactly what I was looking for! Thanks!

[@ghamelvis3555]

good work and collaboration. wish you the best of your tomorrow works.

[@tritonmole]

Very good video. One day i went to some friends house and he showed me an adressable led strip. I looked at the strip closer but did not see any shift registers or driver ic. Only now i realised to investigate if the driver is inside the led chip :D

[@johnrobinson1140]

I think they ear under them

Excellent tutorial. Very well explained. Thank you for the circuit details and LED pins and operation.

[@VantaClawz]

WOW, PERFECTLY illustrated!

[@FOSALGO]

Nice Video, thanks for the tutorial...

[@isettech]

If you wish to integrate the pixels into a DMX512 environment, there are many DMX to WS2811 converters as well as streaming ACN to WS2811. WS2812 uses the same protocol as WS2811, but simply has the chip built into the pixel. A DMX to WS2811 converter is limited to the 512 channel DMX limit, but with a multi universe E1.31 to WS2811 interface (sometimes called a controller) it is possible to send more than 512 DMX channels to one string of pixels by combining multi universes of 510 channels. With 3 channels used per pixel, this is 170 pixels per DMX universe of 510 channels.

[@norulrosu]

very nice explanation. thanks

[@JLveryToxic666]

Hi, can I ask what kits should we buy to make this and what component we need to buy to make full of these, I wanted to make one of these

I had to program 4 of them with an FPGA for college ELEC, so difficult but quite the digital logic exercise.

[@sikirusalau9460]

Thanks for the tutorial. Which software do you use for animation?

[@elciano6599]

Good job. I ask you, is it also possible to fade the light of the LEDs? thank you

Finally I found this video. Thank you!

[@jacquesmertens3369]

Wonderful project. Thanks for sharing! Is there any type of proximity sensor that you can recommend? Since you uploaded this video a lot of new sensors have hit the market, including cheap microwave based movement sensors, to name just 1 category. Any experience with these sensors? Any advantages over the IR based sensors?

[@diezam]

Great video, thank you!

Thanks!

[@simeonmuller6667]

Nice Video. What resistor do i have to use?

[@johnrobinson1140]

I run a 60 led strip straight off my nano with no resistor, no problem. you can use a 100 to 300 ohm I think

[@JawannL]

I learned a lot . Thank you

[@eugenioputtner]

Hi. i just finished the coffee table. First of all: awesome project! I wanted to comment that when i turned on all worked except controling with the app. I don't know much about this stuff but after doing some searching i found that the hc05 module´s default baud rate was 9600. So i changed that in the arduino code and voilà. It works perfect. In case someone is having the same issue ;)

[@PaulChabot]

Awesome! What would you need if you wanted to have the power source and Arduino outside of the spinning ring?

[@vehelix]

Hi, love the tutorial, can you please share the code for the app please? a full run through for all of the components? Thanks.

[@fernsgilbert]

hatsoff to you for the brilliant idea

[@attilahavasi5203]

3:15 Maybe a power supply connection issue. 5V+GND -> Vin + GND

[@nanoSorter]

Really simple and good application development video, like the way things are explained in a simple and clear form like in a 3rd grade home project !!

[@kostadinnedev8521]

Nice! Can you control the brightness of the LED?

what software or tool do you use to make the simulation and code ?

[@williambrewer7879]

Thank you for the awesome tutorial, I found it extremely informative. I am trying to find a mini (less than 2"x2" area) power supply to power a 60 LED strip (same type as shown in your video). So my power supply needs to provide at least 3 Amps. Do you have any recommendations? Thank you again

[@Jagokingkong]

Did you find one?

Hello, ask for subtitles to help you understand the great project. Thank you and congratulations

[@olivier9523]

Can you put the arduino program in the description

[@KyleXY1975]

Thank you for the description you made about the ARGB principle. Before any work, is there a way to easily control if the LEDs are OK or not ? In my personal case, I bought an aRGB led strip to be connected to my motherboard (3 pins header with 5V). However it does not work. I checked with a multimeter the header, I have 5V on it. The MB seems OK. Is there a way to check individuallly a LED, while I don't have a lot of material on the table, a multimeter, few 1.5V cells. Thanks for your support !

[@azpiazu]

I am checking how to set up an argb strip on my desktop and this is really useful (now I only have to know how to work with arduino). Would it be possible to link this using BT with a computer controlled by Aura software from Asus?

[@PatrickHemmes]

thanks for such good instruction, i'm planing to buy a aRGB for outside my pc so my whole setup can fit in the color scheme right now i have 1 static color.

[@davey2k12]

Good guide fastled works a treat but I using 12v strip

[@heinz-peterwolfgangmarcelg1891]

Is it possible to controll several, lets say 6 led strips, simultaniously with one arduino and a single sketch?

[@xXMUurTXx]

Hi great informative video.. I want to ask a question tho... For the place that im planing to place the addressable rgb led strip i have purchased i actually need less the length i purchased.. If i cut from any cutting sections marked, will it affect the argb functioning or cause it not to work properly or even not to work at all in any ways?

[@Mathew69er]

sehr schönes Video ... Kann ich auch zwei seperate RGB LED Stripes ansteuern ?. In meinem Fall 2 mal 1meter. Möchte es in meinem Virtual Pinball verbauen.

[@meyrisaastini1040]

Hi is the WS2812B LED strips are the same as SK6812 LED strips?

[@eiketutdinge]

Also die Bilder sind echt sehr gut verständlich.

[@dærkgift]

Görsel olarak güzel olmuş elinize sağlık

[@zk_6312]

So are neopixels the same as the individually addressable led strips found on Amazon and elsewhete? Though they do have 12v as well as 5v led strips.

[@daviddanieli7238]

Hi, great video. Do you think it will work for a 15 meters strip (60leds/meter)? Or I am going to encounter delay between the command given by arduino and the further led switching color?

[@jakemiller8323]

How does the strip specifically work? How is each diode individual addressable? Aka, what is the wizard behind the curtain of the “Fast Led”library?

[@electrotole849]

Excellent project, a question, how to control the 4-pin WS2813 led strips with arduino, which (+ 5v - Gnd - Di - Bi)

[@makeitathome1327]

Nice video! I'm actually trying to build an arduino project that can control an individually addreseble led strip that has 24 leds using an ir remote. I've got the code and components ready, but I'm worried about the current being an issue. Do you know how much power would approximately be needed, and if so, what gauge/ AWG wire would I need to handle that much current. Also, do you know how to connect a separate power supply to the circuit because I don't think the arduino can handle plugging a power supply into the Power Jack connector.

[@mikereyes6778]

Great video could this kind of application be done for a car and do you need a computer at all time for it to work?

[@aayushsapra3982]

Can you make a tutorial on making of nano leaf with similar parts which is changed by sound and can be easily be applied designes

[@nokel2]

If anyone is having issues like I was where you just keep getting "exit error 1" or something similar, you might need to update the board library, it took me too long to realise that you can still update the version 1.8.2 library without actually updating to a later one (which will also cause issues apparently...)

[@harveyjones4002]

Thanks so much for such a great tutorial! Are you able to tell me. Is it possible to create different settings and quickly flick through them with this? For example one setting might be one solid colour of LED, then the other might be flashing through a specific colour cycle that i've decided. Would it be easy to quickly change from one setting to the other? If so, what would be the best way to do this? Thanks

[@no_life_without_science8343]

Write a function?!

[@dizzleparnizzle]

Could you run parallel led strips from the same signal line from the arduino if you have all powered by power supply. Will that require a different resistor for noise reduction?

[@SuperRossparker]

with those libraries the CHSV params are way easier to use for anyone wondering. it uses hue, saturation and value. plus with the fastled lib it auto loops so you can run a single loop for easy colour cycling.

[@samratsantra8876]

Hi sir I am big fan of you. which development board are using for 600 pcs(10mtr) ws2812b led strip. please suggest. Love you from India 🇮🇳❤️

[@nihal19961]

must the VCC of the 5v supply be connected to the arduino? Would it would if i just shorted the grounds?

[@mahirpokar1528]

Hi is there any way to do this without using the fast led library just for educational purposes?

[@vivekzagade382]

Would you recommend arduino as a reliable controller for home automation

[@carmp3fan]

vivek zagade Depends on what you’re using them for. I’ve had and I’ve seen others have issues with them locking up randomly and requiring resets. If you’re just using them to monitor something and can have them reboot periodically then you’d be fine to use them.

[@swinksstuff]

thankyou, very helpful

[@lucianopazona9976]

Hey! Thanks for the video, I have a question, is there a limit number of leds that arduino can support? THANKS!

[@jiebaef]

yes there is a limitation. the amount of leds is limited by the available mA (take a look at 2:00 and following, just do some maths)

[@lucianopazona9976]

@@jiebaef Yes, I understand that, but I mean when I work with a 60A power supply, with this it´s supposed that I can work more or less with 1200 leds but, arduino can manage this number? Thanks!

[@wasimakhtar3942]

Yes there is limitations of led its depends on your IC bit(memory) you can glow 400 led at a time

[@nikosarghyriou6453]

Does the lenght of the ledstrip affects the resistor we have to use ?

[@HowToMechatronics]

No, it doesn't.

[@Centauriel]

Isn't the Data-In resistor supposed to be 33ohm (from the WS2811 datasheet) and not 330ohm (from the video) ? Does it make a big difference?

[@johnorminski]

Hi. I entered the code for the 'chasing' lights at 4:41 of your video, however received an error message when compiling. Is there different code to use for this function?

[@johnrobinson1140]

check your board, port and boot loader, my nano has to use old boot loader version

[@viktr0643]

Old video but I hope I get an answer: To what extent is this strip bendable? I need the LEDs to be closer to each other so I was thinking if the parts between each LEDs can be "wrinkled up" so that the LEDs would be closer. Or is there a specific cuttable programmable strip where the LEDs are closer to each other? Because I couldn't find one.

[@samueladitya1729]

do you need to connect +5v on arduino if you have external power?

[@HowToMechatronics]

No, just connect the GND of the external power source and the Arduino GND.

[@omerk6969]

yeap finally someone noticed :) you should connect Vin pin

[@oPunkko]

@@omerk6969 it has nothing to do with VIN pin, the OP was asking about doing parellel connect with arduino 5v output to the external power supply... if it's a non rechargable battery youre gonna have some problems

If you change the Arduino board to a simple controller, it's more convenient and cost-effective. And you can control as more led as possible.

Hello, i have a question. After connecting the Arduino to the LEDs, is it possible to remove the Arduino and make the LEDs work still? I am trying to make a product with a remote to change the lights when clicked, but having an arduino in every product would be really expensive.

[@djkadakamc1889]

Hi, is possible to connect 3 stripes of 5meters and use them like a single 15meters line? In this case can i still address single leds individually?

[@oliverer3]

With a sufficient power supply yes, use as short wires as possible between the different strips though and remember that the more LEDs you have the slower the maximum update speed is with about 1000 LEDs you can update at about 30 fps with more LEDs that will be slightly slower.
