WLED Webserver für ESP32 einrichten

In diesem ersten Beitrag zum Projekt WLED möchte ich dir zeigen, wie du dieses auf einem ESP32 einrichten kannst und erste Schritte machst.

Wie du eine RGB LED am ESP32 programmierst, habe ich dir bereits im Beitrag ESP32 mit RGB Stripe gezeigt. Jedoch verfolgt das Projekt WLED ein etwas anderes und ist mehr auf Konfiguration statt Programmierung ausgelegt.

Benötigte Ressourcen für dieses Projekt

Wenn du das Projekt mit einem WLED Webserver nachbauen möchtest, dann benötigst du: - einen ESP32, - ein passendes USB-Datenkabel, - ein RGB LED Stripe, - ggf. einpaar Breadboardkabel, - ein Breadboard Eine Liste mit kompatiblen RGB LEDs findest du unter Compatible Hardware - WLED Project. In meinem Fall nutze ich die 8fach RGB LED Stripe.

Vorsicht beim Betrieb von vielen RGB LEDs am ESP32

Eine RGB LED / NeoPixel WS1812B hat eine Stromaufnahme von 33 mA bis zu 50mA, je nach eingestellter Helligkeit. Wir können am 5V Pin des ESP32 maximal 400mA anschließen, somit können wir maximal 400 / 50 = 8 RGB LEDs gefahrlos, dauerhaft an einen GPIO Pin anschließen. In diesem Projekt verwende ich eine 8bit RGB LED Leiste mit jeweils 8 NeoPixel vom Typ WS1812B.

8bit RGB LED-Stripe Wenn du mehr NeoPixel an deinen Mikrocontroller anschließen möchtest, dann empfehle ich dir eine zusätzliche 5V Stromversorgung. Diese Netzteile gibt es besonders auf ebay.de schon sehr günstig* mit guter Leistung. Hinweis von mir: Die mit einem Sternchen (*) markierten Links sind Affiliate-Links. Wenn du über diese Links einkaufst, erhalte ich eine kleine Provision, die dazu beiträgt, diesen Blog zu unterstützen. Der Preis für dich bleibt dabei unverändert. Vielen Dank für deine Unterstützung!

Aufbau der Schaltung - ESP32 mit RGB LED-Stripe

Schließen wir zunächst den RGB LED-Stripe an den ESP32 an. Wie erwähnt verwende ich ein einfaches 8bit RGB Stripe mit 8 WS2812B NeoPixel.

Schaltung - ESP32 mit RGB LED-Stripe Das mir vorliegende Model verfügt über vier Pins GND, VCC, IN und GND wobei zweimal GND verbaut ist. Somit kann man an diesem Modul eine externe Stromquelle anschließen und für den Potenzialausgleich den Mikrocontroller.

fertige Schaltung - ESP32 mit 8bit RGB LED-Stripe

Installieren von WLED auf den ESP32

Im nachfolgenden YouTube-Video erläutere ich dir, wie du die Firmware von WLED auf deinen ESP32 installierst und über die Weboberfläche den RGB LED-Stripe konfigurierst. https://youtu.be/WkJqqrQeYGE

Flashen des ESP32 mit der original Firmware

Möchtest du wieder zurück auf die original Firmware des ESP32 wechseln, so kannst du dir die BIN-Datei von Espressif laden. In meinem Fall habe ich den ESP32-WROOM-32 eingesetzt und lade mir von der Seite https://docs.espressif.com/projects/esp-at/en/latest/esp32/AT_Binary_Lists/ESP32_AT_binaries.html die neueste Version herunter. Zum Aufspielen der Firmware benötigst du ein zusätzliches Tool, dieses wird dir zum Beispiel mit Python geliefert und findest du unter C:Users%Username%AppDataLocalProgramsPythonPython39Scripts. Der Befehl zum Aufspielen lautet wie folgt: $ ./esptool.py.exe --port COM15 write_flash 0x1000 factory_WROOM-32.bin Es sollte sich dann eine Verbindung zum Mikrocontroller öffnen und der Upload selbständig starten. $ ./esptool.py.exe --port COM15 write_flash 0x1000 factory_WROOM-32.bin esptool.py v4.5.1 Serial port COM15 Connecting....

Festival of Lights… A 'USB Stick' Sparkle Motion WLED driver ✨💡🔌🌟

To wrap up this year, we're doing 8 days (maybe!) of light-filled designs. We started with the Sparkle Motion Mini

which can drive thousands of shimmering RGB LEDs. Next, we were going through some of our NeoPixel samples today and found some "LED Christmas light kit" with star LEDs, its basically these stars

with a little USB plug that has IR, a crummy mic, a tactile switch to cycle modes manually, and a tiny microcontroller that turns the LED selections to different patterns - kinda like this:

The idea is cute - but the implementation could be improved with a lil sparkle motion

! we made a PCB that would fit into the same plastic enclosure but with an ESP32 instead. it's got an IR receiver, ICS-43434 I2S digital microphone

https://www.digikey.com/short/mmv3tthz

gpio 0 button in the 'right' place, 5V 2A fuse, USB-serial converter for uploading/debugging, and two level-shifted outputs. We can probably get the case in quantity or have this be a 'DIY replacement' that folks can use to make their existing setups WLED/xLights friendly.

Programming LEDs

So, progress. I now have 2 LED runs (multiple strips in serial) working on the board, with presets created. I also have the framework for how I'm going to build the cue list. I have a playlists.json file with an object with named playlists. Currently I have been able to test with

jq '.FriarCSMtoLSM' playlists.json |xargs -0 curl 'http://192.168.86.28/json' -H 'Content-Type: application/json' --data

Where "FriarCRMtoLSM" is a named playlist that combines the presets to create the effect. It gets POSTed to the board and it runs!

For the cue list, I will have an array of the named playlists in order. When a cue is called it will look up the named playlist and send it.

I have 2 more runs to add, and a bunch more presets, and playlists to create, but I am now confident about the software. (There is a fugly workaround that I will have to use to get all of the chasers running at the same speed, involving "virtual" leds and a big array , but I've tested that on one strip, so it will work with the others)

The big scary bit for me will be moving from desktop work to the real installation with the longer runs to the first LED.

To no one's surprise the LED lamp project I've been tag rambling about is yet another goddamn benrey but hrrrng colour choice? Gold matches my decor but silver might look better with LEDs. Maybe even white. Thoughts? Base will be matte black or gunmetal spray.

#hlvrai #printing starts tomorrow im too sleepy #ouuuuuhhhh i cant wait to install the lights wled is so fun #the led strip is a delicate 2.7 mm wide nightmare though #i was gonna loosely fold it to be double sided cus wled lets you split the LEDs into sections and mirror the patterns #but i think im gonna have to split it into two separate strips which means tiny scary resoldering #also tried out the clear glow filament in a brass nozzle which no one recommends #it was fine but i'll get a new nozzle anyway

Mosley Lane: Part Two

Pairing: Spencer Reid x Female!Reader

Word Count: ~2.2k

Summary: This is the last piece of the puzzle. The piece before you can finally be set free from all this pain. You're going to do whatever it takes to help your friend and more importantly, yourself.

Warnings: canon violence, canon language, canon talk of death, methods of kill

Season Five Masterlist

Author’s Note: I do not own anything from Criminal Minds. All credit goes to their respective owners. If there are any warnings that exceed the normal death/kills from the show, I will list them.

The rest of the team comes back and you inform them of what you and Spencer talked about with Ashley. Not much is known about Roger other than he worked as an electrician for his entire adult life. He eventually married Anita Wled, the daughter of a family who owns a funeral home. Penelope works her magic on the couple and comes up with some very interesting information.

"Apparently, Anita can't have children. Repeated miscarriages. Eventually, Anita got too old to bear children," she says after pulling up her medical charts.

"The first abduction that closely resembles what's going on here was a decade ago in a different city. Children have gone missing every few years in different parts of the state. I guess they got too many and hired Ashley to help take care of their children. Look how well that ended for her," you sigh.

"We're running out of time. Twenty-four hours have almost passed."

"Look, we all think that Aimee could be alive. That's why there are hundreds of volunteers and officers combing every inch of the county."

"They're dragging the rivers and digging up the woods. That's not gonna help us if Aimee is still with the unsub, if she's still alive out there," Emily sighs.

"What about Charlie? Is he still alive?"

"Sarah believes it," JJ says.

"She's been saying that for eight years, JJ," Derek says. "Have you thought about why you suddenly believe her? Do you think it might be because you're a mother?"

"Excuse me?" you ask, suddenly upset at Derek's comment. "Did you really just ask her that? It doesn't matter if she's a mother or not. We all want to believe a mother when she says her missing son might be alive. The ruse used on Charlie is the same one that happened with Aimee."

"All I'm saying is, if we go from a single abduction to multiple abductions over ten years, that changes everything. We all have to be convinced that's what it is based on an unbiased profile."

"My evidence isn't enough to convince you? You've seen the sketches. You've seen what Roger and Anita look like. You know what Ashley went through. Is that not enough?"

"Okay," Emily says, trying to calm the fire between you and Derek. "What's the ruse? A distraction of a lost child and eight-year-old victims are taken from public places with little to no security. That's not just the same ruse. That's a signature, and I'm not a mother."

"Charlie would be sixteen now. We all know that preferential offenders typically dispose of their victims before they reach puberty."

"Unless his purpose is to help Roger snatch the kids," you say. "He's been with them since he was eight. He's completely submissive to them. He'll do anything they say, including helping them kidnap other kids. It would be why Charlie's body was never found. Penelope, we need more information on the kids that were taken. Ashley's lawyer is going need more evidence for her retrial."

Before Penelope can do anything, Hotch speaks to you.

"Are you doing this because you want your friend out of jail?"

"No," you sigh. "I'm doing this because there is an innocent woman doing the time for a crime she didn't commit. These kids are going missing because of this horrid couple, and it needs to stop."

"Fine. Coordinate with Reid and Garcia." He looks at Penelope. "Go back ten years nationwide. Start with abductions in target-rich environments. Rule out any with bodily recovery, dead or alive."

"I'm going to let Sarah know," JJ says and leaves the room.

"The rest of us need to check out Aimee's abduction site with new eyes."

There is a small possibility that Roger and Anita aren't the ones doing this, which is why Hotch is looking at this through an unbiased lens. You know they are the ones responsible, so you have to gather the evidence before you can do anything else. Ashley deserves someone to fight for her.

Since the year 2000, over two hundred children's bodies have not been found nationwide. In the state of Virginia, there are twelve. Charlie has been on the list for eight years, and Aimee just joined it. Aimee was taken from Ashburn and Charlie was taken from Leesburg, eight years apart. Both of them were taken a half mile from the highway. Karla Hartaway was abducted in 1999 when she was eight from Garrison. Stephen Shepherd was also eight when he was abducted in 2003 from Arlington. Danny Kenman was abducted at four in the afternoon from the mall. His parents are divorced, and he's still missing. Tracey Cain vanished from a park with both her parents present. Jake Wusman was abducted while he and his family were on a picnic.

You got in contact with the families you know are affected by Roger and Anita. Before their children were abducted, they confirmed that Roger would come into their houses to fix some electrical problems. Anita once supplied a family with a casket from her father's business. It's how they knew what children to target.

You're sitting inside the briefing room after just getting done talking to one of the victims' families. You're twirling a pen in your hand when Hotch walks into the room.

"Did you find anything?"

"Everyone I talked to had a run-in with Roger and Anita prior to their kid being taken. Roger did some electrical work in their houses, and Anita sold a family a casket for a loved one who passed. Days later or even weeks, their child went missing and Roger and Anita left town. That's not a coincidence."

"I agree."

JJ walks into the room with a woman who looks like she's seen better days.

"Hotch, this is Sarah Hillridge."

"Oh, we met when Charlie was taken. I mean, you know, you saw a lot of us. I'm sure we all look the same."

"Thank you for coming in. Have a seat."

"Sarah, may I ask you something?" She nods. "Do you know who Roger and Anita Roycewood are? Maybe they did some work for you? You know, electrically?"

"I think I might have known a Roger. I had some electrical work done before Charlie was taken. I remember because we had to stay with a family friend while the work was being done."

You look at Hotch and raise your eyebrows. Your suspects are looking more like the people who are doing this now. They might have taken Aimee, and they might have taken Charlie eight years ago.

"Alright, these represent kids taken from public places." JJ has a map pulled up with pins on it. "Locations are never hit more than once, but there are similarities in each--different malls, toy stores, carnivals, theme parks, and parades. They are places where families should feel safe, and where there isn't much security. That's twelve children over ten years old. We should interview all the families."

"I know a few of them. We had a support group. I mean, most of them have moved on," Sarah says.

"You're here, though."

"I saw Charlie three years ago."

"You didn't tell me that," JJ says quietly.

"My husband didn't believe me. Why would you?"

"Tell us what happened."

"At first, I saw him all the time. I thought I did and from what I understand, that's normal, but you can't survive that way. So Jake and I promised that we would move on. A few years later, I saw him. I mean, it was different. In my mind, he had never aged, but this was a teenage Charlie crossing the street. As quick as he was there he was gone again, but I know I saw him. Jake didn't believe me. That was the day he left me."

"What did you do when you saw Charlie?"

"I called for him."

"How did you know it was him?"

"I didn't, not for sure, so I called for him again. He looked back."

"Your husband didn't see him?"

"It was crowded. He disappeared. I lost him all over again," she sighs sadly.

"We'll be asking those parents to sign up for all that pain again. If they've moved on..."

"They'd take the chance if it meant their kids were alive," Sarah interrupts JJ.

JJ calls in the victims' families and has the entire team talking to them to relive their worst days to get a feel of what happened to them back then. You're in the briefing room on the phone with Abel in hopes you have enough for a retrial.

"I talked to the families of the kids who disappeared. Roger and Anita had contact with them days or weeks prior to their child being taken. We know Ashley babysat for them, and she described the kids who match the description of those who disappeared. Is this enough for a retrial? I'm working on getting more evidence but this is all I have right now."

"Send it over to me. It might be enough to convince a judge for a retrial. I'll be in touch."

"Thank you so much. I really appreciate this."

"No, thank you. I hated seeing Ashely go to jail. She's a good person."

"I know she is," you smile.

You hang up feeling really good about this. You believe wholeheartedly that she will get released this week if not next week. On your way to Penelope's desk, you see families talking with your team, most of them crying as they retell the stories of the worst day of their lives. You knock on Pen's door and walk inside.

"Hey, can you tell me where Roger and Anita live?"

"Unfortunately, that trial ended when your friend was arrested. They dropped their house and sold most of their things. If they are here, then they're using cash."

"Okay, if they have young children, they have to have a house, it has to be local, and it has to be big enough to look appealing. It also might have enough room inside or underneath it to keep the children in. So maybe a farm or something? Also, look for places that are secluded."

"I'll keep looking."

"Thank you."

Once everyone has left, you rejoin the team and Sarah in the briefing room.

"Eleven families have confirmed the same woman, forty to fifty years old, calling for children. In some cases, she even had a child with her," JJ says.

"Can I have a copy of those witness accounts?" you ask.

"Sure."

"She actually used the kids for the abductions? Were they her own or the ones kidnapped?" Sarah asks.

"We don't believe she's a mother. Most predisposed female offenders are not, but they are the most violent."

"You said that she's working with someone?"

"Yes. Roger, her husband. She chooses the victim while they do the riskiest part. They grab the child and manage the getaway."

"We don't know for sure if it's Roger and Anita," Hotch says. "I know what you're saying, Y/N. I believe you one hundred percent, you know this. You also know that we need more proof before we can definitively put this on someone."

"I know," you nod. "I'll keep working on my angle."

"Good. Don't give up."

"This is what Charlie looks like as a teenager," JJ says, putting a computer-generated photo on the screen.

"Um, he's tall and thin. His hair is darker than it was, but that's him. That's Charlie. Why would they take the risk of letting him out in the world?"

"They've had him in their control for eight years. He's either got Stockholm or he's being threatened."

Sarah looks like she is going to break down crying so JJ immediately steps in.

"Why don't we take a break, okay? Come on."

"Okay. Thank you," she sighs and allows JJ to take her away.

"Listen, I had Penelope look into Roger and Anita's address just in case it is them. They sold their house and most of their things once Ashley got arrested. I told her to look at places that are big and spacious, maybe a farm. It might be isolated, especially if Anita is violent."

"I'll narrow down the places they might be on the map," Spencer says.

"I agree with Y/N in that it might be isolated. I mean, there's no way to explain a houseful of kids at the neighborhood block party."

"Managing this many children isn't easy, and there have to be incidents where things didn't go as planned. We should start with domestic calls and disturbances. Concentrate on families who were visited by social services."

"I'll get Garcia," Spencer says and leaves the room.

"It's likely these unsubs were questioned before. Once we narrow down Garcia's list, we should revisit them."

Penelope returns with one hundred and seven places where Roger and Anita could be.

"Okay, I have one hundred and seven families visited by social services in the last ten years."

"That's too many to go door to door. We're gonna have to narrow that down. We need to figure out why they're staying in Northern Virginia."

"Their work could be the key. They could have a child-care facility on the premises as a cover."

"You know, it's most likely a single-income family. Someone has to be home to stay with the kids," Spencer says.

"They've been questioned before, so we can expect a rehearsed response."

"Okay, all of this helps." Penelope narrows down the list. "I have twenty-three families now."

Derek looks uneasy and Rossi picks up on this.

"What is it?"

"We're gonna be knocking on the doors of twenty-three families, and all of them have done something bad to a child. We don't have a warrant. Just our profile. If we get it wrong and leave that house, they'll destroy any evidence they have, including the children."

"That's why you have me," you say. "I'll know immediately if there are children hiding. Even if it's not Roger and Anita, I'll know."

"Just for added precaution, JJ, get an article of Aimee's clothing."

"What for?" Penelope asks.

"It's for the dogs."

How does one get into making gadgets? Do you have an engineering degree, did you make a lot of those pre packaged engineering projects as a kid, are there YouTube videos or websites you recommend? Please share your secrets gadget wizard 🙏🙏

I don't think those prepackaged engineering things even existed in the 90s lol. I did some of the "computer camps" that were big at the time, learned a bit of coding logic that way. a lot of what I learned about electricity and circuits started with working on my car when I was in grad school. old cars have actual logic circuits instead of just defaulting to computers running everything, so you can learn a lot.

then I got a job that let me play with robots all the time, and I also had to fix them constantly, so that helped. then I bought a 3D printer in 2020 and started tinkering with it and using it to build a lot of stuff, but a lot of those memories are locked behind the Great Dissociation Barrier that went up in 2021-2023 because of the abusive marriage I was in at the time, so now I have skills I don't 100% remember developing.

if you want to get into electronics tinkering, my advice would be to decide on a type of gadget that interests you and look for a relevant open source project that's got an active community. for example if you want to make some cool lighting things like this aurora light I made last year, the WLED project is really cool and has forums, a wiki, and lots of youtube videos.

ESP32 Meisterklasse: INMP441 Sounddetektor für einzigartige LED-Effekte mit WLED

Mit dem Mikrofonmodul / Sounddetektor INMP441 kannst du via I2S am ESP32 mit WLED coole LED-Effekte erzeugen. Ich habe dir zuvor in den nachfolgend aufgelisteten Beiträgen die analogen Sensoren MAX4466 und MAX9814 vorgestellt, welche ebenso in WLED eingebunden werden können, aber eine deutlich schlechtere Leistung haben. - ESP32-Projekt: LED-Stripe mit Geräuschdetektor steuern, - Klangvolle Lichtspielerei: MAX9814 Sound Sensor am ESP32 für LED-Stripes

Bezug des INMP441 Soundmoduls

Dieses kleine Modul kannst du über ebay.de für bereits ab 2,5 € zzgl. Versandkosten erstehen. Zum Lieferumfang gehört lediglich eine 6-polige Stiftleiste, welche du noch anlöten musst.

Aufbau des Mikrofonmoduls INMP441

Das kleine Mikrofonmodul INMP441 verfügt über 6 Kontakte. Die beiden 3er-Reihen haben einen idealen Abstand, sodass man dieses Modul auch auf ein Breadboard stecken kann.

Mikrofonmodul INMP441, Vorderseite

Mikrofonmodul INMP441, Rückseite Bevor man jedoch dieses Modul verwenden kann, muss man die Steckerleisten anlöten, hier bietet es sich an, dieses auf ein Breadboard zustecken, da man damit sicherstellen kann, dass die Stiftleisten im 90° Winkel angebracht werden. Du musst jedoch aufpassen, dass die kleine Öffnung in der Mitte des Sensors nach oben zeigt, denn da sitzt das Mikrofon!

Mikrofonmodul auf einem Breadboard zum Löten

fertig gelötete Stiftleisten Technische Daten des INMP441 Moduls Nachfolgend die technischen Daten des INMP441 Moduls: Technische DatenWerteSchnittstelleDigitale I2SDatenpräzision24-BitSignal-Rausch-Verhältnis61 dBAEmpfindlichkeit26 dBFSFrequenzantwort60 Hz bis 15 kHzBetriebsspannung1,8 V bis 3,3 VStromverbrauch1,4 mAPSR (Power Supply Rejection)-75 dBFS

Anschluss des Sounddetektors INMP441 an den ESP32

Das kleine Sounddetektormodul INMP441 wird wie folgt an den ESP32 angeschlossen, ich habe hier gleich das LED-Stripe in die Schaltung integriert. Dieses LED-Stripe wollen wir später über das Mikrofonmodul und WLED steuern.

Schaltung - ESP32 mit Mikrofonmodul INMP441 und einem LED-Streifen

Einrichten des Mikrofonmoduls INMP441 in WLED

Im Beitrag WLED Webserver für ESP32 einrichten habe ich dir bereits erläutert wie du auf einem ESP32 das Projekt WLED einrichtest, hier möchte ich nun anknüpfen und dir zeigen wie du das Mikrofonmodul INMP441 dort einrichtest. https://youtu.be/9zmGUsdW5Mk Schritt-für-Schritt-Anleitung zum Einrichten des Mikrofonmoduls INMP441 in WLED Nachfolgend jetzt die Schritt-für-Schritt-Anleitung zum Einrichten des Mikrofonmoduls INMP441 in WLED. Zunächst starten wir, in dem im Browser die IP-Adresse des ESP32 eingegeben wird. Diese kannst du aus deinem Router entnehmen. Schritt 1 - Soundeinstellungen setzen

Unter den Soundeinstellungen wählst du zunächst den Typ aus. In diesem Fall "Generic I2S" wenn du deinen Sensor wie im Schaltplan oben angeschlossen hast, dann brauchst du keine weiteren Einstellungen zu treffen. Schritt 2 - LED-Einstellungen

Der LED-Streifen wird in den LED Preferences eingestellt. In meinem Fall habe ich die Länge von 30 eingestellt und den GPIO 26 gewählt. Schritt 3 - ESP32 neu starten

Nach dem die Einstellungen getroffen wurden, muss der ESP32 neugestartet werden, hier kannst du den RST-Button auf dem Mikrocontroller betätigen oder unter den Einstellungen "Security & Update" die Schaltfläche "Save & Reboot" betätigen. Schritt 4 -Soundeffekte setzen

Alle Effekte, welche eine Note vorangestellt haben, sind Soundreactive d.h. der LED-Streifen reagiert dann auf die Umgebungsgeräusche.

Fazit zum INMP441 Sounddetektormodul

Das kleine Mikrofonmodul INMP441 ist nicht nur kleiner, sondern hat auch eine deutlich bessere Leistung als die beiden analogen Module MAX9814, MAX4466.

Das dieser Sensor besser ist, wird auch auf der offiziellen Seite zu WLED beschrieben und dieser wird auch dort vorgeschlagen. Read the full article
