How to Easily Control Addressable LEDs with an ESP32 or ESP8266 | WLED Project

[@GermainStaquet]

Note that WLED hosts its own web server on the chip itself, so the app is not even required. Just a web browser is enough.

[@Core-Electronics]

Pinned - Excellent addition, cheers mate 😊

[@bogusbyte]

Was just about to say the same :) That it have a webserver running on each wled device :)

[@reiddennison]

I've had trouble with the ios app, so I like this idea. Question: should I disconnect the power leads from my power supply to the ESP32 while it is connected to my laptop? Or can use the web browser for control on my laptop through wifi?

[@relentlesswrestlingns]

can u please elaborate on how to use the app on the web browser side of things

[@axriticmusic3473]

Website doesn't working,, help me out

[@cac2244]

I spent 8 hours trying to get ESP32 working via Arduino IDE and Blynk (POS) and never lit up and just got working thanks to your video and WLED

[@filipgugo5296]

Yup, spent a week last year trying to get my project up and running using blynk and eventually gave up

[@Sabotage_Labs]

That's awesome. Yea... I was gonna use LEDs and controlling them as a project to help learn Python. But, I found this and was just too easy. It's solid software!

[@dericklong6191]

[@maurocamacho138]

I was trying to make like 30 effects without knowing how to code and i was having a hard time doing it. You saved me from spending who knows how many hours trying to do that. THANK YOU.

[@Core-Electronics]

It is proper liberating hey 😍 happy to help!

[@JustPlainRob]

YO. I just wanted to say an incredibly huge THANK YOU. I've never heard of this until now and it just saved me *literal hours* of coding my own button controller page and patterns for a project. The app is solid (but crashes when I try to autodiscover the LED boards - no worries, the manual add works fine) and the firmware it puts on the board is basically perfect. I will never not be impressed with how fantastic of a web server you can run on an $8 uController board.

[@Core-Electronics]

Yay 😊 cheers for your kind words. No good about those crashes when you are setting it up but very glad I saved you time. These little WiFi ESP32 boards are proper remarkable.

[@ralphm6901]

I followed some instructions to make an Infinity Cube using LED strips and one of these controllers. It's currently programmed to run one of the multi-color patterns during the day, then a different pattern with dim red LEDs from 11pm-8am. It's a decoration during the day and a nightlight overnight.

Great Video! I stumbled upon it while searching for something else! I am in the processes of finish a MK85 Iron Man suit and needed the ability to change light sequences. I happened to have a ESP8266 board laying around! I am having some issues with getting it to install on the board, but i am not giving up yet. Thanks again for a great video!

[@Core-Electronics]

Absolutely a killer application 😊 WLED allows you to sync multiple ESP32/ESP8622 boards together and run LED patterns synchronously, so you could have multiple sections to your Iron Man Suit without having a wire madness connecting everything together. I would love to see that project come to fruition, come write it up on our projects if you have time 😊 ! - core-electronics.com.au/projects/

[@Sabotage_Labs]

What type of ESP 8266 do you have? I've been using the D1 Mini clones from Amazon and they work great. Only have had to use a ESP32 for the sound reactive build of WLED. Just a simple 16x16 LED matrix and mic module. Just wanted to see it work lol. When you say you're having a problem (if still are)... what is the actual problem? I've had some in the past where I had like micropython flashed on the board and can't kill the scripts that autostart in them in like Thoney. I ended up just reflashing then with Arduino ID and made sure there were no other files on the board. Then...it flashed fine with LED. Arduino seemed to be the only one that could get it done. Idk...probably just me lol. For like $15 you can get 5 D1 mini boards from Amazon and be done with it...lol. I got these as my last batch and they've been working just fine. After you get your suit working...you may need some more for the next project lol. You'll love WLED that much!!!! Good luck man.

[@Zeetheepanda]

I love your enthusiasm

[@Mr31Vince]

I use fastled arduino on my ESP32 to drive several hundred pixels on 25 meters of led strip. Use ws2815 strip as its 12v not 5v and therefore much less power injection required. Also the Ws2815 strip has a backup data line so one led failur doesent take out the rest of the strip. The ESP 32 can also be uploaded with new firmware using OTA (over the air) updates so after the first time you never need to connect it back to the laptop or PC again.

[@Core-Electronics]

Sounds like a very formidable set up 😊

[@Taner-Aydın]

Bu detay için teşekkür ederiz. WS 2815 IC şerit led uygulaması, video vb. hakkında detaylı bilgi. Var mı? WS2815 için hangi kontrol modülünü kullanmalıyız?

[@Core-Electronics]

Nice to hear a Turk, Data line for WS2815 are 5V and my understanding is they wont work with 3.3V and its best practice to use a 3.3v to 5v level shifter

[@Mr31Vince]

@@Core-Electronics yes, 3.3v can sometimes work for short runs, but I use a level shifter on the data output pin of the ESP32 for all mine.

[@Mr31Vince]

@@Core-Electronics I also use a second hand HP server power supply off eBay to power the strips. Easy to hack to give 12v output at 80A and much more reliable than a cheap power supply. Power injection at the end of every 5m strip.

[@alexandru-ionelmunteanu3777]

Thank you so much !!!! for finding this you made my life so much easier with this.

[@sethswheelhouse]

What do you do for strips of greater lengths where the current that can be delivered by the esp is a limiting factor or the required input voltage to the strip is 12v? Do I step down source voltage to the esp board to 3.3v, and run 12v to the LEDs, connecting the data pin to the esp still? Do I have to worry about bleed back into the esp, using a diode to ensure the pin is not at risk to be shorted?

This is soo cool. I built one with white PWM controlled LED.

[@wolf_ifritah]

This is fundamentally what I needed to see today - the solution to so many problems I’ve been having syncing multiple leds - ( omg!) I honestly can’t wait to get my hands on this little board and experiment… but I have one question …. You mention early in your vid the option of delivering more 5v power to leds .. this is a fundamental thing I need to learn …is there a wiring diagram I can look at to try grasp how that would function? It would be super useful to be able to calculate how many leds can I power off ( battery a ) then where I need to inject power - also maybe some tips for when LEDS go wrong ..thankyou so much - stay toasty

[@Core-Electronics]

Hey mate, we have some great guides on how to deliver more current to your Addressable LEDs whilst safely powering a Micro-Controller via External power supplies. It is all about making sure that the system shares a common ground and that the ESP32 board is insulated from current peaks (via the logic level converter). Give these guides a look for an understanding on this - core-electronics.com.au/tutorials/ws2812-addressable-leds-particle-quickstart-guide.html and core-electronics.com.au/tutorials/WS2812_and_NeoPixel_with_Pycom.html There are always more than one way to do anything and I'd like to in the future create a definitive guide on powering Addressable LEDS with an external power-supply and specifically the ESP32 boards. Also I'd like to throw in Sound Reactivity to that guide as well for good measure 😊.

[@ConfusedNDazed]

Please do a multi led strip with sound reactivity. Would love to build something like this with 8 strips.

[@drewnoakes]

Great video, thanks! Is it possible to connect these addressable strings in parallel, as you can with non-addressable RGBW led strips?

[@drewnoakes]

I think I found an answer to this. You can run the power in parallel, but not the data. It seems like each LED's address is really its distance from the controller, and each LED passes the message down the line, likely decrementing some counter such that when a unit receives a command with a zero count, it knows that data is for itself, but for counts higher than zero it passes the command after decrementing the count. With this design, running strips in parallel would mean each strip would be a mirror of each other strip. i.e. if you have two strips and send a command to the LED with ID 3, the fourth LED in both strips would respond. Does that match your understanding?

[@sensorchannel]

very nice!!

[@-djs]

Thank you so much for this tutorial. I'm learning the process, I recently purchased 3 WLED pre flashed controllers from Athom, only one is working, so I want to go down the route I should of in the first place, so my question is: Is there a preferred (better) WiFi board I should use?

[@Core-Electronics]

Most important is to get the right ESP32 or ESP8266 IC on the board (and not an ESP32-C3 or similar as these are new boards and the WLED software hasn't caught up). Apart from that so long as you have enough Pins out you will be smooth sailing. Check this guide here - core-electronics.com.au/guides/wireless/esp-32-naming-conventions/

With this set up you can control up to ~30 WS2812 LEDs at full brightness. You can also have multiple ESP32 controllers, all hooked up to the same WLED Phone APP instance that can work simultaneously. That way you can get multiple groups to work together. If you utilised a powerful external Power Supply to drive the LEDs you can power long strips of 300+ LEDs. WLED supports up to 1500 individual LEDs, getting power to all those nodes is the hard.

Good afternoon, congratulations for your videos, they are fabulous. I have a doubt and if you can clarify I would be grateful. I need to put WRGB leds in a case letter. I was thinking of using the ESP32. Once configured and programmed, the ESP32 can work Offline to make a certain sequence of colors and effects, it turns on (ON with a switch ) and the ESP32 starts working and carrying out the predefined routine. Or is there another better controller for this situation. Thanks

[@Core-Electronics]

Thank you very kindly for your comment 😊, I must've missed it before my bad for taking too long to get to it. Your absolutely correct that once configured it will perform the same LED light show that it has been taught as soon as it turns on. You can definitely do a similar project with an Arduino UNO or a Raspberry Pi Pico at a similar price point, however the Graphical User Interface is just too brilliant in WLED to ignore. Here is all the compatible hardware, worth a check beforehand just to be sure you get the right LEDs for your project- kno.wled.ge/basics/compatible-hardware/

[@filipalexandru3129]

Could this be used for stairs? I mean connecting multiple strips in parallel and configuring them as separate segments in the app. How could this connection be realized? directly from the board ? as I can't figure out if you put them in parallel, how to make the data flow. Of course, ensuring that the total power consumption doesn't exceed the maximum current rating of the board.

[@zsavage1820]

Okay the only question I have is one that was NOT addressed in your video or I missed it somewhere.... What is the limit of LEDs before needing more power??? 10 leds? 30 50 WHAT? thanks in advance...

[@Core-Electronics]

Hey mate, As a first note, the max current you want to be pulling through an ESP32 Development Board Chip like the one shown is ~1200mA. Each RGB LED draws approximately 50mA when it is set to full brightness and powered at 5V. That means for every 30 LEDs that you have your LED strip could be drawing as much as 1.5 Amps. Also for those curious, the max current out of a USB3.0 is 900mA. USB1.0 and USB2.0 deliver up to 500mA. That means, for peace of mind during testing, power the system via any USB as it will then not be possible to break the ESP32 by overloading it with the current.

[@offtheworld]

Hi, I have been checking on the Esp32 and the ESP8266 to connect a 60 Led strip.Basically what you just did but double its lenght. Both devices have different names on the plugs so, how to figure out the schematic plug? Like there is no "4plug". Thank you!

Thanks for the video, very interesting and helpful

[@Core-Electronics]

All good 😊

Hi...Can the board store the chosen colour combination and start it as soon the power is ON without tapping the power up button on the app? Thank you

[@maliGoga]

can I control it after installation without wifi? maybe bluetooth?

[@Core-Electronics]

Bluetooth would be amazing but the open source code is just not there yet. You can control it through a Hotspot or just connect directly to the WLED device, via WiFi on your phone, using AP Mode. In the | Setting Up WLED on an ESP32 Board | of the guide you can see the process to access it through AP Mode.

[@prakashsapkota3820]

Thank you so much for this making video. I try to find the code couldn't find how do i get the coding for ESP32 please can you help me.

[@WillMonotoneOfficial]

Is there a central diagram for which pin connects to what? I have a esp32 wroom 32D and can’t seem to figure out what wire goes to what pin

[@silversurfer8057]

very cool. does this also work with the 3pin ARGB devices that are intended for connection to the pc motherboard =?

[@Core-Electronics]

Any PC RGB device that supports the 5v 3-pin ARGB motherboard header should work fine with WLED 😊 Come check out more information here - kno.wled.ge/basics/compatible-hardware/

I have now my 2nd ESP32s nodemcu chip.... When I got the first I had problems "getting it to run" properly (without I knew in detail what the problem was).. It always ran like 10 minutes after it was turned on... Then came across a post somewhere suggesting to use thicker power cables for it.. Thought that was a good idea (instead of thin jumper cables I used år first) that seemed to solve it my first chip has run smoothly ever since... Now I have a new chip I ofc have soldered thicker cables onto it from start (same cables as first one)... But despite that my new chip is actually also acting funny... Gives me only some seconds of connection from Wled.. if at all... so that got me back to zero I have no idea why now doesn't seem logic... It can without a problem run on USB (also how I installed Wled) there it just can't control the led strip when on USB... the connection problem is related to when I run on 5v power supply but there when runs some seconds it can control the leds without a problem

[@Core-Electronics]

Interesting. My first step would be to identify exactly what ESP32 Micro-proccessor your using. This guide can help with that - core-electronics.com.au/guides/wireless/esp-32-naming-conventions/ If the board isn't exactly a ESP8266 or ESP32 board WLED can run into issues. If your using the correct board come jump on our Core-Electronics Forum and write up a post with some pictures of your project. We'll best be able to help you get your system running there 😊 forum.core-electronics.com.au/

[@Rene-kg7pf]

@@Core-Electronics its esp32 nodemcu version 3 both are same

[@Core-Electronics]

Hey mate, following through this forum thread on WLED it seems like its a driver issue with that exact board. They have successfully troubleshooted the problem there though 😊 so you should be able to follow through and do the same - wled.discourse.group/t/wemos-nodemcu-v3-esp8266-ch340g-support/879/14

[@TAKERUP]

I think you over-done it with the lotion.......................that was too smooth. thanks

[@Core-Electronics]

[@RobHerrera]

I have the same ESP32 board, but my on-board LED doesn't light up after flashing WLED to the board. Could my ESP32 be defective?

[@bobpaugh6725]

Thank you for that great video. I was wondering can you control the led with music or have them flash to the beat of a song with the wled app?

[@Core-Electronics]

You absolutely can, there is now a Sound Reactive branch of the WLED Project letting you do just this! Just choose that when your installing the software to your ESP32 by clicking on the drop down menu below the install button. Definitely hit that up 😃

[@ktos9934]

It doesn't show me: 1. Window to type WiFi network name and password 2. Device in app I use ESP serial usb programmer, and ESP-01 and 01S boards. I have few of them from miscontinued project. Tried 2 programmers and few boards. All of them install on different PC ports, but none show next window

[@bryanst.martin7134]

Can this be used without the internet? I am trying to understand how to use a phone app to control some ESPs on a truck, mostly mobile IOT? Like battery monitoring, temps, etc, but also to control valves to inflate tires to needed pressures for specific duties. Driver accesses devices via smart phone or tablet.

[@Core-Electronics]

WLED works best when you have the internet as its much easier to customise. If it isn't connected to the internet the ESP32 does create a hotspot which you can then access using a phone to control the LEDs. To control/indicate all those different features potentially a Raspberry Pi Single Board Computer would be better for the task. Come hit up our forum and we'll best be able to make recommendations regarding your project for you - forum.core-electronics.com.au/ Also a completed project like this definitely belongs on our Projects page! core-electronics.com.au/projects/. It helps/inspires the community + there is Store Credit up for grabs!).

[@skizzzurp]

Do you need to have Wi-Fi to change the LEDs? Could I use this in a car using USB from the headunit for power and adjust the LEDs from my phone without a home wifi connection?

[@coskukaplan7142]

Hi There. So I am trying to do a painting with embedded systems. I have vehicle in the painting where I cut the taillight part on canvas. I will be attaching the addressable LEDs behind the cut portion on canvas. But I want to use a remote controller, and once I press a button on the remote, I want the taillights to turn on as it would in a normal Audi. I also want to add a engine sound by placing a small speaker. However, I am not sure how to continue to this project. And I need to finish it by next week for a birthday present. Could you suggest steps for me? I will highly appreciate it.

[@Core-Electronics]

Heyya champ! Excellent sounding project with a tight deadline 😊. I highly recommend hitting up our Forum as we will provide the best possible plan from there - forum.core-electronics.com.au/ Personally I think a Raspberry Pi Single board computer would be your fastest bet to make a complete system.

[@knownepal4330]

I want to ask a thing that you have done with only one strip. If we make a combination of strip and make a board then Can we scroll text on them. By using your app

[@Core-Electronics]

I reckon that could work. This fellow seems to have used JINX to achieve scrolling text with WLED. I reckon that would be the easier approach - github.com/Aircoookie/WLED/issues/1122

[@dieruebe007]

Can i also use 5 meter led strip, has the controller enough power?

[@Core-Electronics]

All depends on how many LED nodes are on that 5M led strip. If more than 30 you will need to supply it with more power using a separate power supply. This guide has a section demonstrates how to include this extra power when using a long LED Strip - core-electronics.com.au/guides/raspberry-pi/fully-addressable-rgb-raspberry-pi/

[@dieruebe007]

@@Core-Electronics Thank you very much for the response.

[@tibornadas7371]

Hello! Very good video, understandable! It works for me in the browser, but the app (ios) doesn't see it. Can somebody help me?

[@metallicaandchimaira]

How would you connect multiple LED strips like this? I am working on a lamp that responds to sound but I want to connect 4 different LED strips with 15LEDs per segment to the ESP32.

[@Can_I_Have_A_Go]

Hi after watching video I noticed that leds don't look that bright. How to het maximum brightness? Different type of rgbic? Or is it power supply related. .

[@Core-Electronics]

Hey mate, is just the Studio Lights (behind the camera) battling against the LED lights on the table. Rest assured the LEDs are very bright. If I stared at them directly for too long it would cause my eyes to go funny. If you want even brighter LED lights come check this guide out - core-electronics.com.au/guides/how-to-drive-high-power-leds/

[@Sulli00700]

Question: I'm looking to use this with an outdoor setup and the LED strip I want to use runs on 12V. Would I run the positive line to a 12V battery, and use a buck converter to drop the board's power to it's needed voltage, then connect all of the commons?

[@ElliottVeares]

How would you connect 2 wire LED's such as those that use the ws2812 protocol?

[@Core-Electronics]

So this guide demonstrates WS2812B LEDs. Some 12Volt variants have 2 pins for data (WS2813). You would only need to connect to 1 of the data pins and ensure that correct voltages were being sent through it (logic/data Voltage is 5V in that case).
