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..!

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

[@Ultrasilverr]

very good introduction to the RGB addressable LEDS. Thank you

[@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.

[@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 ;)

[@ChrisHiblerPinball]

Thank you. This was enough to jump start me with simple Arduino programming.

[@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?

[@AzzYung]

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!

[@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

[@pacowang283]

You make it look so easy. Brilliant sir!

[@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.

[@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...)

[@rushabhnagda9267]

Thankyou for this detailed explaination

[@olivier9523]

Can you put the arduino program in the description

[@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?

[@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

WOW, PERFECTLY illustrated!

[@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 !

[@PaulChabot]

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

[@shvideo1]

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

[@attilahavasi5203]

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

[@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

[@kostadinnedev8521]

Nice! Can you control the brightness of the LED?

[@mak.1ps]

Yes you can

[@sikirusalau9460]

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

[@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.

very nice explanation. thanks

[@heinz-peterwolfgangmarcelg1891]

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

[@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 !!

[@FOSALGO]

Nice Video, thanks for the tutorial...

[@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.

[@electrotole849]

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

[@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

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

[@fernsgilbert]

hatsoff to you for the brilliant idea

[@HackingDutchman]

Some say you need a capacitor to protect from inrush current from the psu. However, they never specify how many amps the psu uses. But when you want to calculate what capacitor you need to use you do want to know your amps. A lot of them just say: use a 1000uF 6.3 at least. How do I choose the right uF to protect my LEDs?

[@alisonfernendes3295]

Nice project

[@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?

[@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?

[@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.

[@darkgift3127]

Görsel olarak güzel olmuş elinize sağlık

[@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?

[@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?

[@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?

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.

[@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

Is neopixel strip and this same?

[@TechieBaksh]

Yes

[@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.

[@woogieboogie9803]

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

[@juanbolivar35]

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

to write program more easier i think

[@darrenraymond119]

Hi. Great channel. I have just completed building the table as a gift for my parents and as they do not have android phones i am trying to use an LED remote control with the IR sensor connected to pin 53 with very little success. Is it possible to use remote in this way instead of android phone?

[@HowToMechatronics]

Hey, glad to hear that. Well you can't really control these ws2812b addressable LEDs with a remote. As an idea, instead of remote control, you could add like two potentiometers knobs in the table itself, and control the colors with them.

[@puneethkumar703]

@@HowToMechatronics it is a good suggestion

[@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

[@alestbest]

This is a perfest tutorial. Thank you.
