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.
Thanks, I'm glad you found it useful!
How To Mechatronics Every day is a school day!
"2 for the powering and 1 for the data, 3 for the money 4 for the show"
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 love these collaborations - really gives each of you more scope.
very good introduction to the RGB addressable LEDS. Thank you
You are a master! As always pretty elegant and clear videos. Thanks for share your knowledge.
You make it look so easy. Brilliant sir!
oh my god THE TABLE!!!! I WANT ONE
Outstanding work. Thanks for your time and expertise.
Thank you!
Great as always!
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?
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.
Awesome! What would you need if you wanted to have the power source and Arduino outside of the spinning ring?
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!
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?
WOW, PERFECTLY illustrated!
Whoa!! This was the first arduino dyi video I saw 2yrs ago and now I'm ready for code
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!!!!!!!
Very informative. This is exactly what I was looking for! Thanks!
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
Thank you!
Yeah, LED cubes are pretty cool, but I couldn't say if or when I would make one.
Cheers! :)
Thanks for the tutorial. Which software do you use for animation?
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?
good work and collaboration. wish you the best of your tomorrow works.
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?
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
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.
Can you modify this as water tank level indicator using WS2812s and Arduino
Thank you. This was enough to jump start me with simple Arduino programming.
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!!
Hello. Please please tell me we're you buy or order top of this coffee table (that glass??)
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
I believe I could use the Blynk app on my iPhone to achieve the color adjustment capability. Thanks for this tutorial!
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.
or even a Nano, one 8 bit shift register would work
How to do that ? Any guide for that?
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?
Hello, ask for subtitles to help you understand the great project.
Thank you and congratulations
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.
Excellent tutorial. Very well explained. Thank you for the circuit details and LED pins and operation.
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?
Your effort is appreciated. Your English and presentation is perfect. Your voice is sincere. Your video is truly awesome. Thank you very much for your time and consideration.
Thank you!
@@HowToMechatronics My pleasure.
Finally I found this video. Thank you!
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
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
Write a function?!
Can you put the arduino program in the description
Excellent project, a question, how to control the 4-pin WS2813 led strips with arduino, which (+ 5v - Gnd - Di - Bi)
Is it possible to controll several, lets say 6 led strips, simultaniously with one arduino and a single sketch?
Good job. I ask you, is it also possible to fade the light of the LEDs?
thank you
Can you show where you connected the Cap on the circuit?
Nice! Can you control the brightness of the LED?
Yes you can
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
Did you find one?
how can i control brightness of leds using this library, please help.
hatsoff to you for the brilliant idea
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
I think they ear under them
are
Thanks for this video. I what to know what type of power supply should I use ? Is it continous ? can I use batteries ?
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.
Really well explained!
let's say I have an RGB led strip, how would I make the pins on the led strip compatible with Dupont wires?
A truly awesome video, thank you for sharing. I came to learn about LEDs and got a bonus introduction into the art of Bluetooth and creating an android app. Thank you!
Glad it was helpful! Cheers
Thankyou for this detailed explaination
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.
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.
very nice explanation. thanks
what software or tool do you use to make the simulation and code ?
I learned a lot . Thank you
Hi, love the tutorial, can you please share the code for the app please? a full run through for all of the components? Thanks.
Nice Video.
What resistor do i have to use?
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
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?
hey i want to ask you if you can save the patterns on the arduino or dosen´t the the light strip reapeat the pattern that you make while the arduino isn´t conectet to the PC?
Hula HoopVEVO when it's not connected to pc it does what you have programmed to your arduino
Hi is the WS2812B LED strips are the same as SK6812 LED strips?
Hey! Thanks for the video, I have a question, is there a limit number of leds that arduino can support? THANKS!
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)
@@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!
Yes there is limitations of led its depends on your IC bit(memory) you can glow 400 led at a time
what hole on the pad do I connect the data to?
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 !
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...)
must the VCC of the 5v supply be connected to the arduino? Would it would if i just shorted the grounds?
if you need to control 2 or more strips, how do you specify "Channel X, Leds[y]"?
to write program more easier i think
I had to program 4 of them with an FPGA for college ELEC, so difficult but quite the digital logic exercise.
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?
But how is this LED strip working really? What is the protocol implemented inside FastLED library?
Hi, how many LEDs can I use? Thanks
Nice Video, thanks for the tutorial...
Helloo, I am using the same led strip(20 leds total on the strip) with a 5V 1,5A Power Supply. I see that you used a 330 Ohm resistor but I only have 220 Ohm resistor, will I end up destroy my led strip with the 220Ohms or is it still ok?
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?
check your board, port and boot loader, my nano has to use old boot loader version
Hi there, What is the maximum of the led chain please ?
With an external 5V adapter for strip how many leds can we power at full power?
thankyou, very helpful
where you find led strip
can we use this to control a 15m long led strip?
This is a perfest tutorial. Thank you.
Great video, thank you!
Thanks!
Görsel olarak güzel olmuş elinize sağlık
Is it possible to do that with stripes connected up to 40meters?
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 ;)
Hi is there any way to do this without using the fast led library just for educational purposes?
Can the Addressable LED be wired in parallel? I have 6 runs that I want to do the same thing at the same time?
Hi: Thanks for this awesome video. Can we control these strips without using fast.h library, Thanks in Advance
If you're using arduino, then no. But if youre using some other type of controller, then yes. =)
@@hevimetallimias Thankyou. But i found a way in which there is no need to use fast.h library.
I have 2 strip of ws2812b 5meter. Total 10meter 60/m 5volt.
Can you tell me which adapter will be better 5v 20amp? Or 5v 10amp? I m using arduino to program. Thanks
Would you recommend arduino as a reliable controller for home automation
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.
how do you connect the library to the arduino ?
Does the lenght of the ledstrip affects the resistor we have to use ?
No, it doesn't.
What if you you have the 12V WS2815, can you show how you would wire that using an Arduino
Dear Dejan, good evening.
Just one question. Taking in mind that I have 168 leds I need an external power supply. After I connect it EXACTLY as you instructed, since the power supply is on, the result is the strip to light on, right???
Or is it that the Data cable will prevent from lighting up until the sketch is uploaded in the Arduino ...????
Please enlighten me....thank you in advance...!!
Dear Dejan, I greatly appreciate your concern to reply.
But....now I'm confused.
You see....even without Arduino device connected...when I power on the strip...the strip lights on...!
+ cable to 5V line, GRD to GRD, and D without connection , and the strip goes on...!! How can this happen....?
The same of course and with the Arduino Nano on the breadboard, and Dline connected to D5 pin. Without sketch uploaded.....! The strip goes on.
It is for sure a WS2812b............5V.
@@Yannis_Nik. u cant connect 168 led with single wire, connect power supply at both ends of led
