Chris, I can't express how much I appreciate these videos. I've learned so much from you since following your channel. Thanks again!

I always love your videos. I think we’d all love to see a walk through of your setup and all the areas you’ve done. Thanks for great content!

I have to say that every video you published is awesome. I now have a guide on how to set up my lights in my home lab. Great job 👍

The "Bouncing Balls" and "Dancing Shadows" effect were fire!!

Very clear and nice video !

This is the video that has led me down a new hobby path. Thank you.

Great video. I'm planning on doing 2 zones with a total of approx. 30m in length, my supplier sent me a few options for LEDs . WS2811 / 5v WS2815 /12v WS2811 / 24v Can't wait to see more of your tests, narrow down my choices.

THE KING OF LEDS

What a perfect timing. Just got my ws2815 a little while ago and started to experiment how i can get it running with an esp

Great content as always! Question: is there a good way to waterproof the channels as opposed to buying the IP65 variants? Cheers!

I eneded up using the WS2815s 60LEDs/m for my permenant christmas lights and they are great. You gotta pull the trigger since you are the king of RGB lights

I’m following this tutorial pretty closely along with the how to solder video , and installing wled video but my esp32 board pin layout looks a little different. I don’t see a pin named d4 and the ground pin is in a different spot. Is there a different pin to use ? Is it just the output gpio4? Thanks !

I finally got this working thank you so much for a great video! I had so much pain as ESP32 boards come in different varieties, but i worked out that simply changing the GPIO pin within WLED done the trick! Just an additional question but when you are displaying what appears to be two sets of LED strips, are these connected to the same controller and in series? Now i have this first stage working with 2 LED strips in parallel, my next stage is to extend to 30m around garden for new year light show! Trying to work out if i'm best having separate controllers or just connect the full 30m with any additional voltage...Not sure if anyone can advise on how i progress from here?

Chris, thanks for the great videos. It has really helped me understand the differences between all the available LED light options. I'm going to have a go at putting together a project for a night club using 130 meters of WS2815 on four separate circuits. I'm curious if you've done any side by side comparisons of the available controller units from BTF Lighting. I really like the results you're getting with WLED with the ESP32 project boards, but by the time I make these commercially usable and put them in project boxes, it's going to be more trouble than buying the off the shelf controller complete with their remote controls.

Hey Chris! I noticed the wled program has the led voltage set at 5v default. Do I need to change this if I'm using this same 12v strip?

Hi Chris, I have 5050 led strips which run on 151 smds , can i connect it to ESP32 and control with wled?

@ChrisMaherDIY - What LED settings are set in WLED for the WS2815? I see some kind of limiter and its defaulted to 5v 55ma or something? What is the proper setup for these? How do you calculate the right power supply given lets say 3.5 strips used of these (1051 LED's in my case)?

Hi! I hope you can help me... I listened a lot of things abouts de led strip, and one f the is: is necessary use a "Logic Level Shifter". it's true?? what you (or anyone else) can say about it? thank you!! and your videos are amazing!

Can you tell me which defuser you are using here, the regular spotless or the 30x30 corner? Looks epic by the way.

Thanks Chris! just would like to confirm as I'm a newbie when it comes to this stuff. So if I wanna do 5M of less, 5V DC setup should be okay? don't need an extra injection? Ta

Thank you Chris.

On the esp32 are you just plugging the +5v into the 5v pin and the gnd to the gnd pin. The same as you would when you would power it via the USB port and the +5v pin and gnd pin would be then connected to the LED strip? I only ask as I tried a 12v power supply using your directions, and it worked for a bit but then the esp32 overheated and the wifi module no longer works. So made me wonder if the pins on the esp32 are connected differently in this configuration.

Hi, nice Vid. One question: What is the maximum length of the data cable from the controller to the strip? So that it works without errors. Is 3 meters too long?

Hi Chris I’ve followed this video to the letter yet yet I do not get the same results. When I plug LED strip in to power supply the full reel illuminates. When I introduce ESP32 with WLED the strip behaves erratically. I’ve tried using the voltage adapter to power the ESP and also separate supply, both yield the same result. I’ve seen reference in the web to Logic Level Shifters but never heard/saw you use one in your projects. Could this be the answer?

Hi Chris, i have meanwell 12v 12.5 amp with WS2815 and wled, but the led doesnt want to turn on. i can access the WLED, do you know why?

Dying to see you try out some of the COB dream color... these are 24V... wild for no voltage drop, but crazy density: BTF-LIGHTING FCOB WS2811

Will this work with a Wemos D1 Mini? Or what voltage does the data lines need?

hey Chris, Can you please help me out. I'm using(BTF-LIGHTING AC100-240V to DC24V10A Max240W Suit DC24V1A~DC24V10A Switching Power Supply + BTF-LIGHTING FCOB WS2811 RGB IC Chip Flexible High Density Uniform Light Chasing Color LED Strip DC24V + EPS 32) I followed all the steps from your videos but when connecting LED strip to power supply the LED wasn't turning on. I used the multi meter to make sure i have 24V and checked the other end of LED and it seems it has 24V no light appears. I also damaged 2 EPS 32 by connecting straight to the power supply not knowing that it only work with 5v.Thanks

I’m going to use this set up for outside near a spa that has 2 stages of stairs I want to wrap both outside edges under the stair stages are these leds for outdoor I would really like to get your input

So, I've been wondering. The power supplier and the buck converter, they have convenient little screw holes for mounting. What do you do with the esp32 dev board, leave it floating?

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

I WANT TO PUT A PUSH BOTON and chance the secuence of the light it is possible with the SP32? and the WLED?

Man thanks for the demonstration I have been chasing around on how to do it with the ESP32 board, Thank you so much🙏🙏

Looking great! is this good for 65 ft outdoor project ?

my friend, how much leds the ESP32 hold? and how much ampers, do you know? because i want to control 40meters, but probably the ESP won't support so much.

Hi Chris, can you say me where i can download your backround music. Its great👍

Hi Chris, I have watched all your videos on youtube. I have learned a lot and thank you for that! Have you tried using WLED and ESP32 in old 12v RGB analog led strips? I'm not sure if it's even possible, but I'd be really happy if you could make such a tutorial. All the best for you! Best regards, Tommi

Thank you for tutorual.

Could you do a video using wled and fcob rgb ic strips? Ty the setup in wled is different then regular ic strips

How can you get the white light on the led mines doesn’t give me the option for white ?

Great video as always! I was wondering if i can do remote on/off through wled with this wiring setup? I noticed that the power is directly connected to the strip while the esp32 only controls the data channel.

Hello. just bought Just bought ws2815 but I can't get it to light pure white. I think it should have the white colors. Can yours do it?

I'm using the BTF power convertor with the esp32s board and these power strips. The strips won't come on. I have 12v coming out the power supply. The esp board is connected to my phone and I can control that. But the led strips are not turning on. I've tried 2 different strips but nothing. Any idea? Oh and I went in the wled app and put it on the w218x with 300 led.

If you wanted to have the LED's controlled by an AC dimmer switch with a 12V dimmable LED Driver, could you control the LED's with an ESP controller with a different power source?

Would love to find a diagram or detailed tutorial of how to do a long run with these. I’m doing trim of a 50’ rectangular room.

Great videos Chris , just getting into LED designing and starting with my sons room renovation, quick question on using the ESP32 or other WLED controllers- Have you ever used any type of enclosure for them to keep them safe and protect them , or just tuck them up somewhere hidden most of the time and not worry about it? TIA Steve

Looking for help. I have these same lights I can't ge the app to recognize the lights even though I can work the lights via the desktop app. Once I disconnect from the computer the phone app does not find the lights or it did once bujt told me they were off line and I could not access them fro m the app. I deleted the lights and now I can't find them again.

Another Great Video! Can you provide details on how you "mount", and secure the ESP32, or the ESP8266 boards? My current project will use 3 boards, attached to the BTF-LIGHTING WS2812B lights.

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 (channel letters). 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 itself. Or is there another better controller for this situation. Thanks

Does it matter if you use a 3 Amp or 5 Amp power supply on these? I see you are using 5 AMp but curious if its ok to go with 3 Amps

Quick question. Did you use power injection on the other end? Or is the full 10m run just one power source with unnoticable diminish to brightness? I was considering getting a nice big 12 v 15A 180W PSU for my project using 15m of ws2811 but now I am having second thoughts.... Additionally, I am curious to know of it is possible to connect the data wire (green)to 2 led strips and have the same data sent through them I was thinking 5m and 10m( with power injection ) since the big power supply has 3 pairs of +v -v I can use. Let me know your thoughts. Thanks!

I will be glad if you can reply urgently. I bought WS2815 led strip. I wanted to test it with the 12volt output (12.5A) transformer I have. I connected the red and white ends of the strip led to the plus and minus outputs of the transformer, but it did not light up. I will get the ESP 32 i microprocessor later. My goal is to pre-test. how do i do this. Did I make a wrong connection? Or are the led strips faulty?

great video, really makes me want to do this myself. I'm wondering though, is there a zwave device i could use instead of the wifi esp? I have so many wifi devices that anywhere I can use zwave i'm trying to do so as to not congest the wifi

I'm making a Halloween prop that is an inter dimensional portal and the inner ring I want to run LED strips with a lighting effect like its spinning up, I see lots of tutorials on how to do all this in WLED and what not, but what I'm missing is how to trigger a light show using my various prop controllers. they all just send 5/12/24v signals to turn channels on or off, but I also have DMX options in some and i'm learning how to use their various software with DMX LED decoders. Basically I don't want to trigger the shows from a phone or a button, I wanted it to be automated in a line of animations that are all being triggered by these prop controllers. have any ideas?

Are you running the strip directly off the ESP32 data line - that's 3.3V... doesn't the WS2815 need 5V or is it 3.3V tolerant ?

what about if i want to hook that up outdoors? do you shove all that in to a box or something?

You did exactly the application/operation I had in mind. Is it okay if we power the ESP 32 module from an external source? For example, with a mobile phone charger with a 5 volt output. Because it will be an expense to buy an adapter that reduces 12V to 5V. For this reason, I want to use the existing adapter I have.

FYI professional always use 24v strips - longer runs and more reliable binned LEDs. But what you do is perfectly acceptable and COOL! Keep it up

does the tutorial work for 12v ws2812b 5m 144 LEDs?

can we buy a Wled controller for 4 pins neon led?

Great video, Chris! I have a question regarding your 12V/5A = 60W power supply recommendation. According to the specifications, a 5M WS2815 LED Strip will take 90W to power (probably at full white with no degradation). If we consider 20% higher (90W *1.2), it will be 108W. Does this theoretically mean we should be using a minimum of a 120W power supply? That is twice as much as what you're recommending. Am I understanding this correctly?

Is the wire gauge based upon the voltage, amps, or wattage? I'm not quite sure how this works yet. basically I have about 13 metres of LEDs that I need to power. I'll use power injection at multiple places, but the overall requirement is 300 watts at 5V, which is 60 amps. Is the wire gauge based on amps, watts or volts?

HI, thanks for your video. If you use two LED Strips, does the data wires connect directly to the Esp (parallel) or does it need to go from strip one into strip two (jn row)?

Any links for the same but in RGBNW?

I am confused how supplying 5v power allows this to work. I thought the esp's output voltage was 3.3v no matter what was the input. I currently am using a 12v supply and it is not working with my WS221812B though

Great tutorial! Why do you wire the backup data line to ground? Wouldn't it be better to wire it parallel to the main data line? What are the pro/contra for either method? Sry for the noob question. Appreciate your channel, thank you!

Hey Chris wonderful video, I was wondering if I would be able to power 3 esp32 boards off of one 12-5v converter? Also can the esp32 be connected to a google home?

Great video, just one thing ive always been wondering about, is there any way I can hook these LED lights up to be powered by a PC powersupply, or motherboard (using the 4pin headers), and using the controller by cutting the wires on the 4pin from there? Just a thought, Idk too much about circuits anyway.

I'm curious how you managed that without a level shifter? I have almost the same setup (ESP32 and 5m of BFT WS2811) and things are going crazy with random color changes or flickering/brightness changes.

When can we get that power source comparison video. I am about to take on a project and want to know what source to use to not be overkill but not be to small. Over all I will be doing two 5m strips for under and above cabinet lighting.

Hello great video and nice channel!!! May I ask why you connect the blue wire to the 12V negative, what is that wire for?

Hi there, super clear video. One questoon I have still is the following: I have exactly the same BTF ws2815 strip. I can't use WLED drivers unfortunately for my project (making a wordlclock) but i am familiar programming in arduino language myself. This leaves me with the following: my ESP32 MH-ET-LIVE board has - i think - 3.33V data out at IO33 (but i think at all data outputs to be honest) even though i drive it with step down 5V like you do. I have read that the 3.3V data signal would not be enough for the WS2815 strip to take it in, and that i need another shift level convertor to bring the data to 5V again. I dont see you use it, so I wonder if it is even needed? Regards from Holland

Help.... I can't find this info anywhere yet, still looking though. First off, @ChrisMaherDIY thank you SO MUCH for all of your tutorials. After much debate and a few returns of Govee lights I took the plunge into ESO, wled, and 2816b lights to do it right!❤ However I still have a few non addressable LED strips already in my space which I want to leave for now, Yet control those with an esp 32 board and wled as well.... Can this be done? Can I control a dumb non addressable 12v LED strip with WLED and an esp32 board? If so, is there a walkthrough somewhere?? Thanks for anyone who can help.

hello dear, these rgb shine brighter than ws2812b?

Ledstrip 12v keeps burning at the spot between the cables and led strip Tried multiple cables and no cables are touching. Also the led strip seems to be "starting up" is turns on sections at a time. After some sections the burning starts happening. Im no electrical engineer and a friend told me this was how it needed to be done. Please help.

Hey Chris! I've been watching your videos for a while, but became a subscriber just recently. I was wondering if you could help me with my room's re-design? I wanted to have individually controllable LEDs throughout the perimeter of the room, which measures about 67 feet. What would your suggestion be for Power supply (Single or multiple), number of points of power injection, can 4-5 sequentially connected strips of WS2812B be controlled by just 1 ESP32 board, or would a 12v LED strip setup be better. Appreciate the advice. Cheers!

Hi, thanks a lot für this video, I have got nearly the same stripes, just the 144/m and soldiered multiple of them together, in total 908 LEDs but, I get strange glitches of colour bursts every few seconds. Any clues?

Are there any 12v RGBW led strips that work with WLED? All the ones with dedicated W seem to be 5v and I would prefer to avoid injections along at the runs. Anyone?

I have a few questions. 1) When we use a mobile phone adapter instead of the voltage reducer that converts 12 volts to 5 volts in the video, would it be sufficient to supply 5 volts from the mini USB input of the ESP module? 2) When we use a telephone adapter, is there a need to apply voltage to other points of the module? 3) How many pins of ESP32 did you connect the green wire to?

Hello Chris Thank you for the information. Could you possibly do a short video on powering esp32 with usb rather than buck converter. As I have already own 3 esp32 boards.

Hi. Is it possible to turn the lights ON with an ordinary wall lights switch that turns on the 12V power supply? Can it be set to start the initial strartup procedure via WLED on ESP32 when powering on with wall lights switch ? Thanks Roman

I have tons of used power supplies ive removed from old desktop and all in one computers, the output 3v 5v and 12v depending on what wires you connect to, could i use one of them to run both the lights and the board?

Very mesmerizing scenes! Song was very fitting too. Name of the song? 😬

Wouldn't it be nice if you made Esp32 energy with a phone charger adapter instead of a 12V to 5V step down regulator?

Hi, can I use just jumper as a wire or do I need 18awg wire to connect ws2815 + esp32 + power supply and converter?

Hey Chris, Actually I wanted to mount a 10m LED strip with an ESP32 and WLED on my wall, but currently the Govee M1 LED strip is on sale and very cheap to get. And now I have two questions: Can you get the Govee M1 Led strip without the power supply or do you necessarily need the second? And can you pair two LED strips in the Govee APP so that they play a pattern together? If this is not the case, then I would probably go the ESP32 and WLED route. With kind regards Christian from Germany :D

Chris great awesome helpful videos. Do you recommend any one specific profile channel or LED brand to use on ceilings/walls for lighting used as main light source? Similar to what is show for more contemporary design layouts? How do you determine what brand and setup to use for different lighting use. I.e. 1) Main light source 2) Entertainment Audio/Video Around TV 3) Gaming 4) Bar area? 5) General hallway ceilings/walls? 6) Garage ceilings for more brighter lighting 7) Stair case under stair tread lighting Also Govee seems to have a really user friendly package deal with products, power, and switch however if you need lighting for example threw out ceilings leading to one switch for on/off how do you setup this? Or another example would be having multiple LED strips on different ceiling/walls that leads to one power source and control source how would this be setup? Any help is greatly appreciated. Thank you!

Hang on... how are you powering a 5 meter strip of 60 LED/meter WS2815 lights with a 12v 5A power supply? The BTF websites specs say that each led draws 0.3 watts of power and on a 5 meter strip thats 300 x 0.3 = 90 watts. Am I missing something? Are those actually 30 LED/meter? I'm trying to connect four of these together in parellel and power them accordingly but now I'm worried my wattage is way to the high with the power supply I have in mind.

Is this the 144LEDs/m variant of WS2815 or the 60LEDs/m?

Hi, how do i connect the 4 pins from the LED the NodeMCU with the ESP8266. If there are three its just Vin, Gnd and D4. Planning to use the microUSB to power the device. Not sure how to connect if there are 4 connections!?

thanks! how many 12 volt individually addressable leds can i daisy chain and power using esp32?

@chris maher Any videos on this type of setup using voice control like Alexa, Google, etc?

Thanks Chris! Has anyone used the 24v BTF512AC strip from BTF Lighting? I'm trying to get it to work with WLED but can't see to find any information. They are 5 pin.

Hey Chris, what does this 12V LED strip makes better than the 50% cheaper WS2812 one? In my eyes there is no positive arguments, if you don't use it at 100% Power. Correct me please if I am wrong or missing points.

Great video man I'm building a campervan and the whole roof will have this setup. Question I have is I'm probably going to be running around six 16' led strips and I see that they make 200-300 watt drivers. You're running 60 watts for 2 strips so would you say it's 60 watts per 32 feet? Or 600 less? Also my entire system is running off 12v so I can power these strips directly from a battery bank. Is there a driver that doesn't need to convert 2 AC so I can avoid the plug? Thanks for the input dude. It's helping my idea bc closer to reality

Hi. wonderful tutorial, it pushed me try. Just becouse i had a lot of 2815 that i use for shows on stages, and i was searching a good solution to avoid distance limitation with cables. Unfortunatly my first test returned a full white strip, blinking a bit, with tiny rgb noise. Backup and Gnd wired toghether as you... i try to ask, beacause looks so simple but i'm not seeing the proper light at the end... any suggestion? i'm powering the esp32 with a phone charger through usb, and the ledstrip through a DC power supply. maybe is that? i bought a pack of 12Vto5V, that will arrive in few days thanks a lot!

Plz tell me what I'm missing here regarding your 12v 5a power supply. You used 2 full 5m strips which appeared to be 60 leds/m. LEDs are 0.3w each so 60 LEDs x 10m = 180W / 12V = 15amps General rule of thumb is to add 20% to the power supply so how are you running those lights (which should be using an 18amp power supply) on a 5a?

If I understand everything right - for WS2815 model is not real to connect controller with remote control, only WIFI or Bluetooth?

Did you use any additiona power injection on the two 5 meter or you powered booth from one side?
