Thank you for taking time to post this information. My goal is to enable a webcam to record video and audio when motion AND/OR audio is detected, so this seems to be a good start. Motion detection with a PIR is not difficult. I am curious if the KY-037's analog output can be used to record audio.

So the ESP32 could transmit an SSID and act as a hotspot.. and simultaneously the esp32 runs a webserver? If so, what kind of data thruput could you expect? Perhaps that's the idea behind dual-cores.. one core does the AP, the other does the webserver? Regardless, if the ESP32 samples the ADC 2000 per second, and updates the web page with every new sample.. what will a client , connected to the hotspot/web-server, see as the sample rate? Or would it not be real-time, and instead the client must refresh the page manually to get fresh ADC samples? Perhaps the user could talk back to the ESP32 via the web page as well? BTW, very new to all this, just ordered an ESP32 8x8 RGB board, and an ESP-PROG JTAG programmer... hoping to use Visual Studio Code to code/debug on the esp32! At first I was thinking of an Android application, that transmits an SSID and acts as a hotspot.. then someone passes a puzzle quiz, I bridge my mobile cell data to the hotspot.. however, I was thinking I should first learn programming on a microcontroller like the esp32 before going to android

Why not work on arduino uno r4 wifi

Hey man I have got. A problem .My raspi pi zero 2w doesn't have any option to enable the raspi camera but if I use open cv to stream on the pi itself sometimes it works (mostly) but I am unable to get this code running

I think Klipper love over priced hardware. No explanation there like you. It's great.

Thank you so much for the the tutorial! Using this method to stream video, could you take a still image of whatever the camera is pointed at and save it?

Thanks for the video. What is the filter bandwidth setting for? I'm familiar with sensor fusion but forgot some concepts that are probably related to said setting.

I want to use ESP32 AP to allow pass-thru connection between the clients. i.e. have three cell phones connected to ESP32, such that cell phones can see one another on DHCP-designated IP address. Possible?

I get the error "python3-picamera" has no install candidate And as such I have no legacy camera support in the menu either

raspberry pi doesnt like it when you install libraries to your main python install now

So what would I need to change in the config file to utilize the 3.5mm jack instead of using a USB mic? I want to stream some audio from a source that will use the 3.5mm jack to input the audio. Thanks for the video. Thumbs up.

Full code please

you go too fast

Amazing video! Clearly explained! I hope you keep up the good work!

The angle measurements in my case are not very accurate (a 90° angle is interpreted as 60°). I'm using the same code as you but with an Arduino Nano. Do you know anything about this?

Does that library take values from the DMP or does it actually do sensor fusion of gyro and accel to get the angles?

Hey, I keep getting the error Connection Timeout, I've checked my wiring and every step, some times it works, then it stops suddenly, what could this be?

Very useful!

Exactly followed but when opens thonny it says, Device is busy or does not respond. Your options: - wait until it completes current work; - use Ctrl+C to interrupt current work; - reset the device and try again; - check connection properties; - make sure the device has suitable MicroPython / CircuitPython / firmware; - make sure the device is not in bootloader mode. Any idea??

Thank you for this! very helpful! subscribed :)

Is raspberry pi 4 supports?

The goat

I like how you discussed what the different settings actually mean. I was wondering why you wouldn’t just pick the 16G setting. Now I know.

Will you be making more videos about xedge

Will this work with raspberry pi 5?

Great staff thanks for sharing

@mmshilleh : Nice video. I have an issue setting this up. Rather funny one. I use rpi pico w on thonny. Windows 7. I have setup the ap as access mode , created a socket and send a web page with form input text boxes with method =POST. I can get the wifi with ssis as Pico-W on my computer and gets the html page on the computer browser. When I enter the data in the boxes and send it to back to pico. It receives the headers etc without the data But if I connect my android phone, and send the data on the same html page. I get the entered data as a string (That is fine). But If i use the method=GET , I get the data on both ( along with the URL as standard). One thing I have noticed on computer " Inspect elements -> Network. On both loading the page , initially the status shows and 200 and after a couple of seconds (failed) net:ERR_CONNECTION_RST , But the page is loaded on the browser and I am able to enter the data into the boxes. On submit the status shows as pending and after a couple of sends , it changes to failed. In the Payload, i see the entered data. On thonny , I get the POST headers etc but without data. It seems for some reason the connection from browser is not maintained till all the info is send / received from picow. I did a ping test for the picow IP address 100 times and it worked like a charm without any loss. So why is computer browser not able to send or receive the last bit while Mobile is able to do that ? What are the possible solutions ( network, socket ) or the computer (I tried opera, chrome, internet explorer and on another laptop with edge). Are these stable with micropython or switch to c Thaks in advance

Could you access the IP address of the internet connection where the raspberry pi, or other devices in that network if you are already connected to one of the devices (raspberry pi) in that IP with tailscale? I am already connected to one of my miners, but my second one keeps falling out, dropping connection, and I wish to access it from abroad to change settings...

Does it record when the phone is locked? maybe with a wake lock

Hello, I'm only starting to learn about raspberry pi's and micropython now, I copied your code to make the LED blink but I got this error message: ModuleNotFoundError: No module named 'machine'. I'm assuming "machine" was just the name you picked for it, but what should I use as my name to make the code run successfully? Great video btw!

Thank you for sharing

how did you get the library for "machine"?

Thoroughly enjoy all your videos. Would really like to see some slightly more advanced c++ videos.

You should have shown people how to find the USB audio/Mic. aplay -l arecord -l This does not usually work out of the box as the PI needs to be told to select either hw: 0,0 or hw:1,0 etcetera. Also you will need to change the password im icecast2 config or youll get a nag constantly . It can be cumbersome setting this up for beginners

Where is the react client video clip?

When i am trying to create image, i am getting below error, Could you please help me on this => CACHED [3/8] COPY ./chrome-installer.sh ./chrome-installer.sh 0.0s => CACHED [4/8] RUN chmod +x ./chrome-installer.sh 0.0s => ERROR [5/8] RUN ./chrome-installer.sh 0.3s ------ > [5/8] RUN ./chrome-installer.sh: 0.291 /bin/sh: line 1: ./chrome-installer.sh: cannot execute: required file not found ------ Dockerfile:12 -------------------- 10 | 11 | RUN chmod +x ./chrome-installer.sh 12 | >>> RUN ./chrome-installer.sh 13 | RUN rm ./chrome-installer.sh 14 | -------------------- ERROR: failed to solve: process "/bin/sh -c ./chrome-installer.sh" did not complete successfully: exit code: 127

Hello, I'm curious about the sampling rate of your code. Because I have to make sampling rate reach 1000 per second. Do you know how can I improve?

Is docker-images a repository present in the Amazon ECR? I get 'The repository with name 'docker-images' does not exist in the registry with id '123456789''

This code not work for me. I read I should add time delay after initialization, but still get error EIO. MPY: soft reboot Traceback (most recent call last): File "<stdin>", line 30, in <module> File "<stdin>", line 20, in init_adxl345 OSError: [Errno 5] EIO

Cheers @Shilleh. Great content + well explained.

nice video! if i want to make it full duplex, to talk like a telephone over the internet, i can configure another PI with icecast server and both playing each other stream? it will work?

Hi, it doesn’t recognize Picamera2. I’m using a library called “camera” but I don’t get information on internet about it

Sorry,I have a big problem. I have to connect mpu9250 with raspberry pi zero w. I couldn't install mpu9250-jmdev, what should I do? Thx

Does this work via ethernet?

Dear author, guide is good, but for some compass/chips models we have CCW value (heading) result. For example, you turning to right (CW) and geting 1,2,3,4,5..., then from 0 (north), you are turning to left (CCW) and getting 359,358,357,356... I'm getting the same, but reversed: Your: 359 | 0 | 1 My: 1 | 0 | 359 Do you have idea about how to fix it?

the point of accessing over any network is that i don't have the access to my pi's network, so, ideally, tail scale must start automatically on pi's boot, and have to authenticated automatically.

I came find your videos just trying to program my pico using visual studio. I started playing around with microcontrollers this year and content from creators like you saved me so much time. Seeing you program through the terminal is another layer of discovery for me too and is really a eye opener into how deep the rabbit hole goes with these things. Really cool stuff man and I'm looking forward to more content as you are extremely knowledgeable it seems. Thank you

Thank you for this! I was looking for an easy way to set this up for a Pi 5 and this came along at the perfect time!
