WLED & ESP32: The Dynamic Duo of DIY LED Projects

День тому

In this video, we will show you how to set up WLED for your LED lighting project using an ESP32 microcontroller and an ElectroCookie board for the breadboard, and then install everything into a 3D printed enclosure.
We will explain the hardware components you need, including the ESP32 and ElectroCookie board, as well as the LED strip, power supply, and connectors. We will then guide you through the process of assembling and wiring everything together on the breadboard.
Once the electronics are set up, we will demonstrate how to download and install the WLED firmware onto the ESP32 microcontroller. We will also explain how to configure the firmware settings, including WiFi connectivity and LED strip layout.
Finally, we will demonstrate how to mount the components into the 3D printed enclosure.
This setup is perfect for those who want to experiment with custom LED lighting projects and want to create a sleek and professional-looking installation.

Truly appreciate the effort you went through to not only explain how to do this, but also why you did things you did. I went from not having soldered (solderless breadboards and jumper wires were my friend) to having a fully custom ESP32 controlled WLED setup. (And a nice reason to make a 3D printed design to hold the setup!) Might be time for me to create a new video.

Thanks for this video, ElectroCookie is a new discovery for me, but I'll definitely be looking at getting some. Also, those barrel connectors are awful, and good on you for pointing out that they top out at about 3A at 5V. I think it's borderline criminal that if you buy a 15A power supply, it'll come with one of those connectors. I've melted more than one from going above 5A. Total fire hazard.

Just getting the hang of WLED for lighting effects on a model railroad. It's... pretty good, but I'm finding there is a lot of flickering in some of the animations. I'm also fuzzy on the toolchain required to create my own sequences. Learning as I go...

@MakersMashup Рік тому

You can do a few things to address that. First, check to see you don't need that 62 ohm resistor I spoke about in the video. Sometimes that alone can help. Keep your data line short. If you have LED's spaced very far apart you might be better with multiple controllers synced together vs. running wires to each LED. You can also control the FPS on the LED's as well. Thats in the config. Another great tip is use a faster controller. ESP32's can control things faster than an ESP8266 and the like. There are also SPI LED's out there. Those I understand are super fast but I havent used them personally. Drop into the discord and post some photos of your work if you have some free time. I'd love to see it. It sounds fascinating.

@yardmull3t273 Рік тому

@@MakersMashup I would recommend you use a "sacrificial LED" to drive your data line. This is a very simple change that a lot of people miss or over-think. The controller (ESP32 or ESP8266) outputs a 3.3v signal on the data line, but the 5v LED strips expect 5v. If you put one LED from your strip close to the output of your controller, you will be driving a 3.3v data line a very short distance and a 5v data line on the output of the first LED will drive a lot longer to the LED strip. This is cleaner, simpler, and cheaper than using "level adjuster" logic on your controller board. Search "sacrificial LED" for more details. I am running over 1000 LEDs around the eaves of my house without using any resistors or capacitors. I also recommend the capacitor for a power filter, but I didn't use one and have no ill effects for LED runs of greater that 24 feet. Power injection is required along the LED strips though. Driving a 3.3 data line for anything but very short distances will cause flickering.

@yardmull3t273 Рік тому

I should add - you can also configure WLED to ignore the sacrificial LED: Config => LED Preferences => Skip first LEDs: 1 This will cause the first LED to not light, but instead will just boost the data line signal to 5v. There's no point lighting the LED in the 3D printed box, so you can keep it out of your animations, etc.

@djcarroll4080 2 місяці тому

[QUESTION] First, thanks for the amazing video!!! I'm new to electronics and just recreated this project. However, I'm hooked up to a 300 led strip, and thus, a 20 amp power supply. Ultimately, my question is, "How many amps can the electrocookie handle from a 5V 20amp power supply?" I've got the power supply connected to the electrocookie leads via wago connectors (no barrel connector), but then I've got the led strip connected to the other end of the electrocookie (just like yours in the video). So, ultimately, the 5V 20amp supply is traveling through the electrocookie and I'm worried about it not being able to handle it (although I'm really only getting ~5amps going through in reality). I've searched everywhere I can think of online for the specs on the electrocookie, but to no avail (again, I'm new to electronics, so I'm not sure if I'm looking in the right places, or if this is even something I should be worried about). Can anyone help!? Thanks!

@darkhog1 11 місяців тому

Thanks for the video! Regarding the 1000uf capacitor voltage - since we are pairing with a 5v power supply we should use a capacitor that is 2-3x the voltage, correct? So a 10v or 16v? Thank you!

@MakersMashup 11 місяців тому

16v are pretty common but yes, you need one larger than a 5V one to handle any ripple voltage. Either would be fine IMHO.

@michaelc1042 6 місяців тому

Great video, thank you for taking the time to make this. Question, I built my house over 20 years ago and "Home runned" Cat5 wire from 6 different kitchen cabinets to a central location in the basement. The maximum length of any of the runs is about 30 feet of cat5 from cabinet to basement. Could I power and control (ESP35) all 6 cabinets from the basement, or do I need to apply additional power at the cabinet? Will cat5 carry the necessary power to the under-cabinet led strips. Probably no more than 2.5 feet of led strips under each cabinet. I hope I am making sense and I greatly appreciate any suggestions on how to finally install under-cabinet lighting for my wife 🙂

@outbakjak 6 місяців тому

Depends if they're 5v or 12v or 24v strips, if they are ≥12v, your ESP32 dev board would need to be able to be powered by that voltage as well, there are many different ESP32 dev boards, mine can be powered by 5-25v if I recall.. but otherwise there's no issue sharing a power supply with the ESP32 at the front, it'll only take what power it needs, and if that wiring has been sufficient so far then it should continue to be. Though to me, if they are 5v strips I'd say 24awg cat5 is a little small. That said if it's been working so far, you have an ESP32 board that supports the same voltage, then you can just use the same power supply you've been using and do it exactly as he shows here.. assuming I understand you correctly :) Edit: the esp32 will use very little power, and assuming they are RGBIC light strips (they have a power and ground pin, and 1 single data pin or 2 data pins in the case of ws2813 to control the colors, and NOT the kind that have a Red pin, Green pin, Blue pin and GND pin, those won't work) then the data output from WLED is also only a tiny amount of current. If your strips are just White only and controlled via PWM controller, or not individually addressable, as in if they're not able to have multiple colors on the same strip at once, then WLED will not work to control them without additional tinkering with relay modules. If they're ws2812b or some other strip where you can control the color of each individual "pixel" then you're good to go

@MakersMashup 6 місяців тому

Way to much to cover in a YT comment so you might want to drop into the discord if you need help on this one. The short of it is that I don't know if cat5 could carry the current and signal that far without any issue. Personally I would just use a local power source near the cabinets. Or simply use the CAT5 for powering (Providing it can handle the current) the ESP32 and lights at the cabinet. With WLED you can "Sync" multiple devices, so you only need to control one of them to enable you to set multiple lights. So should you need say 3 different ESP32's (because the cabinets are not near eachother) you can simply have one be the master, and the slaves will update as needed. I would use this vs. Running wires from a central location with a central ESP32. The implementation is going to be quicker because you wont have to debug trying to make it work with CAT5 cabling. Just some food for thought. If you pop in the discord, glad to discuss further.

@lorenzopalma4088 5 місяців тому

Hello and thanks for the very easy to follow presentation. I am using a similar setup with an ESP32 and WLED which I am using to power 18 WS2812B LEDs in a company logo medallion. What I lack in my configuration are the resistor and the capacitor. And now I finally understand the reason why some of my LEDs have stopped working. what size capacitor and resistor do you recommend if I only have 18 LEDs? They are individually wired WS2812B LEDs. I will use the electrocookie as well as like the way you have everything fit well together. I neglected to mention that I have a small 5V power supply, which I realize is not even necessary given that I only have 18 LEDs. Also, do I need to worry about leveling up the 3.3v to 5v for the data connection? I look forward to your reply. Thanks, Lorenzo

@MakersMashup 4 місяці тому

You could possibly have a different one but its unlikely. It is a tight fit, it was designed to be a pressure fit. If its too tight you can reprint the enclosure and adjust the X/Y Size compensation or horizontal expansion setting in your slicer to give it a bit more room. It sounds like your printer calibration may need a little adjusting. ;)

Yes, just wire up a momentary switch, between ground and one of the GPIO pins. You can then select the pin you used in the LED section, and then under macros, set Button 0 to up to 3 macros for short, long, and double press. I haven't tried the other options yet, but you can also wire up analog buttons or other sensors with a threshold.

@SianaGearz Рік тому

Standard 2.1mm/5.5mm connectors have a 2A rating. While stretching them to 3A is perhaps just a little iffy (probably fine at first, could degrade substantially in the long run depending on luck, don't sell products like that, don't bet your house on it), 5A rated PSU or terminal block adapter for these connectors plain shouldn't exist, just entirely out of question, no point even trying. A technique is to connect ground at the digital input end of the line and voltage at the free far end of the LED chain. Then the voltage loss is distributed across the whole string evenly and the digital retransmission between the LEDs re-adjusts the signal just right.

Look forward to your answer, thanks!

@MakersMashup Рік тому

Great question! 60w at 5v is around 12A of current. I wouldn't push more than 3 or 4a through the PCB itself. I was not able to find a data sheet for it. Some back of napkin calculations (if they used 2oz copper in the PCB Manufacturing) is a 3-4mm trace width which would support about 5 amps. So I wouldn't recommend using the PCB for high current applications. You can get a fairly inexpensive bus bar/terminal block that can easily handle the 12A for your project amzn.to/3n7xFwp - Just use this for the power itself, you can have a positive and negative one if you need multiple outputs. If you need a 3D Enclosure for this, PM me in the discord I can cook one up in about 5 minutes to enclose these. In my higher current applications I usually wire power outside of the PCB with the exception of the power going to it. Have your power come into the terminal block/bus bar, then just send power to the board's power rail. Then send the raw power from the block to your LED Strips. Thanks for the really great question I may do an another video on high current applications using these devices.

@MakersMashup Рік тому

Oh, one more thing. If youre using a high power supply, you have a bus bar built in! amzn.to/421j3NR as an example. Just run one of the 5v lines to the electrocookie, and the rest to your LEDs in the run. No need for another bus bar as these basically have them built in! There are also many many 3D printed enclosures for these supplies.

BUT if I use a USB cable to the ESP32 while it is still attached to the ElectroCookie everything works perfectly! I can't figure out why. I've now built 3 boards and all of them have the same issue.

I found a way to get mine to work. I only have the green data wire coming off the electro cookie to the LEDs and power to the LEDs straight from the supply. I don't know why it won't work with power off the electro cookie, it just doesn't.

@MakersMashup 5 місяців тому

Drop into the discord and I can help you, will likely need a screen shot of the wiring. My initial thought if you're not getting power is that you didnt solder the join points at the middle of the electrocookie? If you used the side rails for power like the video you may not be connecting them properly to the vin and gnd on the esp32. Check the voltage at the pins on the ESP32 with your meter. If you dont see 5v there with your meter than you don't have voltage going to the ESP32. The USB would obviously solve this problem which is why its working with the USB. Sounds like something is not connected from the electro cookie to the right VIN and GND pins. Check those with a meter and go from there.

I'm going to join the discord because now the issues are that the ESP32 isn't being found in the WLED app, I think I've really improved the build on my electrocookies with every version so this is really stumping me.

First off, thanks for the video. I followed all the way through; but, can't get the led's to be controlled by WLED. I can program the ESP32 and connect to it; but I am unable to change any of the lights. The default is not all on and I get about 10 lights on and they stay on all the time. Someone suggested a level-shifter on the data line. Thoughts?

@MakersMashup 5 місяців тому

10 lights on sounds like the default few lights on. Check you've set the string pin and length of the string in wled. That would be first to check. How long is the string of LEDs you're using?

I did confirm both the length and gpio pin. I noticed on my DevKit board (DevKit V4) by Expressif that GPIO16 is labeled "OD/IE": Output Disabled (After Reset) and Input Enabled (After Reset). Does WLED enable the output on GPIO16 after reset?@@MakersMashup

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? Does the board work with a 12v power input ? Thank you

@MakersMashup 6 місяців тому

Sure does, just set a default inside WLED and when it powers on, you get that effect. Most ESP32 boards can take a 12v input. Check the datasheet for the board to be 100% sure. Otherwise a cheap 12->5v regular can be put inline for the ESP32. Which I suggest you do vs. supplying the board with 12v. While you save on a component that costs maybe 1 or 2 dollars, any power spikes are handled by a proper regulator vs. the very cheap one on the ESP boards. Ounce of prevention...

@MakersMashup 6 місяців тому

I don't know your skill level but I would not suggest altering the car wiring. Many times lights carry high current loads and creating a splice can create a fire hazard. I would suggest using a switch to turn on separately, an optical sensor or a hall effect sensor/relay to turn on WLED. Its an interesting idea and should work fine, just be cautious about modding high current hardware unless you're familiar with it.

@milwaukeeautoworx 6 місяців тому

just a suggestion. an easy and cheap way to power 5v leds on 12v DC is to pick up a couple 2.1 amp usb lighter chargers, pull the boards and wire right near the lights. that way you have a good strong 12 to 14v going right to the lights and then a step down right before the leds. i like pulling the boards, get rid of the rest. after they are wired i put them back into the housing and heat shrink over that. for $5 you can get a solid 5 amps of power with headroom.@@meguinness1116

@karelkral6812 4 місяці тому

What about level shifter? WLed is controled by 5V, Esp32 out level is 3.3V. Do I need a level shifter?

@MakersMashup 4 місяці тому

In my experience with most modern LED lights a shifter is unnecessary and tends to cause more confusion/issues than anything else. I would try it without one first. If you have problems then a resistor is usually the easiest fix. 62 ohm resistor on the data line. The Cap is honestly the most important factor in the circuit and having sufficient power to run the LED's.

You could do that if your entire string of LED's is less than 500ma of current. Its really not recommended. It does work however.

Thanks for subscribing! Really depends on your budget but here are my usual go tos.. I personally love Bambu's. They work well, easy to use and I can send a print without thinking about it. I own 3, I love them and use them daily. Multicolor is awesome. They are a bit pricey though. The A1 is a bit more budget friendly and you can get it for under $500. The A1 Build volume is a little small but could easily print cases and things like that. If you're new to printing the Bambu's will give you a short learning curve to the hobby. shareasale.com/r.cfm?b=2354729&u=3946301&m=138211&urllink=&afftrack= #ComissionsEarned My budget favorite is the Kingroon KP3S.

The Capacitor. The link takes you to a 1000 uF, 50V variant. Help me understand this. Shouldn't this be 5V, or does it not matter what V is used, I see there are 25V and 50V variants online.

You just need the capacitance. Voltage should be close to your application. Think of it as a max safe value. So a 25v is fine.

I decided to go with the ws2813 rather than ws2812, for resilience. Then realised that there are four wires instead of three. Red green blue white. Do I need to go to using WS2812B? Or is there a quick bit of advice to sort my predicament?

@markbrookes5715 4 місяці тому

I take it that unless I am working with more than one strip, daisy chained after the first strip, I can ignore the fourth wire, in my case the blue one I believe it is because there are red/white/green as in ws2812. Do I understand this correctly?

Yes, the only change is that you'll need to power the ESP32 from a buck converter to get the voltage down to 5v. for the microcontroller and sound reactive module since those pull off the vin on the board. WLED has a diagram that shows how to wire in the buck at kno.wled.ge/basics/getting-started/

I don't think that you made clear when you mentioned injecting power further into the string of leds that you shouldn't be mixing power supplies. If necessary, the power to the ESP32 should be from one power supply and that supplied to the LEDs from another. That is important for any project, the grounds can be common but the power inputs should not.

Can you program this board to sync with MIDI input?

@MakersMashup Рік тому

Sort of, but not directly. There are a few options though depending on your need. If you're looking for Lighting controls, WLED does support DMX which is used for lighting controls for DJ's, events, etc. If you're just looking to sync this with Music without the sound reactive piece you can use LedFX which allows your PC audio to create a sound reactive effects on 1 or more WLED instances. So if you have 5 of these, they will all sync together. Finally if you truly need MIDI support directly, then check out any number of the MIDI to DMX apps out there. Lightjams being one of them. That would take your midi and then convert it to DMX which WLED natively uses. Would loved to know what you have planned, it sounds exciting.
