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!!

[@jimbarrett2152]

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! :)

[@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

Glad it was helpful! Cheers

[@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 ;)

[@EasyHomeMadeProjects]

Great as always!

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

[@davey2k12]

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

[@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.

[@spsnow7128]

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

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.

[@heinz-peterwolfgangmarcelg1891]

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

[@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

[@norulrosu]

very nice explanation. thanks

[@miq4326]

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?

[@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...)

[@eiketutdinge]

Also die Bilder sind echt sehr gut verständlich.

[@chanchalsakarde2768]

Can you please guide on how this setup can be used as water tank level.. as water fills in tank led strip show as how much tank filled.. Thanks in advance

[@christopherpond3770]

Just FYI, the first thing you should do if your project doesn't work is switch the pin. My pin 7 wasn't working, but I switched it to 3 and the strip lit instantly. I'm using the Linux Arduino IDE, so maybe that's the problem, or maybe I burned out the pin, I dunno. Hopefully, it saves someone else some trouble.

[@woogieboogie9803]

how can i control brightness of leds using this library, please help.

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

[@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 !!

[@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 !

[@kostadinnedev8521]

Nice! Can you control the brightness of the LED?

[@mak.1ps]

Yes you can

[@JawannL]

I learned a lot . Thank you

[@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?

[@3dtexan890]

Can you show where you connected the Cap on the circuit?

[@nimishkhot]

Is neopixel strip and this same?

[@TechieBaksh]

Yes

[@fernsgilbert]

hatsoff to you for the brilliant idea

[@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?

[@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 🇮🇳❤️

[@paramtalwalkar7197]

If you use an external supply it needs to be connected to the Vin port on the arduino not the 5V.

[@HowToMechatronics]

Well it depends what voltage is the external supply. If it's 5V you can connect it to the 5V pin of the Arduino. If it's from 9 to 12V then you need to connect it to the Vin pin.

[@yahavalon1278]

HI THanks alot for the video! Could you tell me which is the cheapest but right arduino model (or other) for driving ALITOVE WS2812B Addressable LED Strip Light - I want to make marshmellow head mask? Thanks uri

[@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?

[@beastold1320]

Is there a way to connect 2 different stripes to 1 Arduino and control them parallel but with different patterns?!

[@swinksstuff]

thankyou, very helpful

[@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

[@alisonfernendes3295]

Nice project

[@darkgift3127]

Görsel olarak güzel olmuş elinize sağlık

[@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

[@danny-ww6xn]

i want to make this project withn flexible WS2812B LEDs and with bluetooth and with mobile application please help without proximity sensor

[@RifaiAL]

Can you help me build an RGB LED strip strobe light for use with my levitating water effect project? The color combination of RGB strobe LED's must be selectable.

[@electrotole849]

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

[@yusufylmaz6417]

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.

[@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?

[@TechnoSAP]

Nice video

[@mahirpokar1528]

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

[@juanbolivar35]

if you need to control 2 or more strips, how do you specify "Channel X, Leds[y]"?

[@MustafaMertDemirci]

to write program more easier i think

[@fredmaury7804]

huge thank you!

[@zakariamimouni9394]

WoW it's Great work

[@OmkarJadhav999]

Thanks a lot man :)

[@PantherJagger]

What if you you have the 12V WS2815, can you show how you would wire that using an Arduino

[@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?

[@sub-arts128]

it seems, that 1 led is not powerfull enough to light up 1 complete raster. what is the measurement of 1 raster?

[@djkadakamc1889]

I have a long ledstripe 5 meters. Every 50cm there is something that I don't know if it's a resistor.

[@KiwiMaker]

wow i always wondered how they made individual leds turn on. I see my RGB strip lights dont have the tiny chips in them :(

[@JNDlego57]

Yes, the individually addressable LED’s each have the WS2812B chip, which makes the cost of these strips infinitely more expensive than the basic RGB ones you have. But they’re extremely useful, just be prepared to spend at least 2x as much for the same number of LED’s you could buy for the basic RGB strips. If part of your project involves just stationary uniform colors, I’d use the standard RGB strips for that

[@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.

[@gaminggalore3921]

so what should i get for the power

[@SRsatron]

Very nice 👌🆗

[@wasimakhtar3942]

Sir pin 7 is not the pwm pin then how you diming the led and for dimming I think we have to choos pwm pin am I right?

[@TaufikAngga-xk6ej]

Yeah but PWM pin just generate the square wave using timer, So u can do it without pwm pins, just programing like PWM pin.

[@mudassiriqbal3191]

With an external 5V adapter for strip how many leds can we power at full power?

[@vichope6408]

Hi how many led can uno support?

[@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?

[@In33dc0ff33]

Why do you need the resistor?

[@BillyGates1721]

you should NOT connect Plus of the external power to the arduino +5V pin. If it happends that the external power-supply has a lower voltage than the arduino +5V-pin this situation acts as a shortcut which will overload the onboard-voltage-regulator of the arduino. Did you do test this situation thouroghly? As a "how to mechatronics channel you should do so.

[@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?

[@jarno2427]

Wat is the maxime leds you can connect

[@wierdgamesfromme1595]

Would an arduino uno work the same as the arduino mega?

[@noibi23]

Is it possible to do that with stripes connected up to 40meters?

[@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.

[@alltechnorepairingcreative5486]

Nice brother🤝

Sir Namaste , WS2812b 5V . Led strip. 5v ok but which ams adapter match sir.

[@taranagnew436]

let's say I have an RGB led strip, how would I make the pins on the led strip compatible with Dupont wires?

[@HemanthKumar-cz6ly]

Can I give more than 5 V to the led
