Würde mich mega darüber Freuen :)

Sehr gutes Video. Ich bekomme jedoch den OSError: [Errno 5] EIO nicht weg. Traceback (most recent call last): File "<stdin>", line 26, in <module> File "<stdin>", line 16, in init adxl345 OSError: [Errno 5] EIO Schon mal Danke falls jemand Hilft :)

I have several of those.

humm what if use a efs as storage ? not bad

thank you!!

Hi, thank you for this tutorial. Can I use 12V fan with this L298N board? Will the fan work?

hey i was trying to build the docker, but i got the error failed to solve: process "/bin/sh -c dnf install -y atk cups-libs gtk3 libXcomposite alsa-lib libXcursor libXdamage libXext libXi libXrandr libXScrnSaver libXtst pango at-spi2-atk libXt xorg-x11-server-Xvfb xorg-x11-xauth dbus-glib dbus-glib-devel nss mesa-libgbm jq unzip" did not complete successfully: exit code: 1 what do i do ?

sir , i have a problem please help me, i am Unable to use chrome profile session using selenium webdriver on render deployment in my local machine its properly working for my chrome path but in render or any other cloud service which path i need to define because i used local chrome path in my local machine but render don't have direct access to my computer files right? , this is my code please tell me how to manage chrome sessions- CHROME_PROFILE_PATH = "C:/Users/DEEPSAHA/AppData/Local/Google/Chrome/UserData/Default" chrome_options = webdriver.ChromeOptions() chrome_options.add_argument(f"user-data-dir={CHROME_PROFILE_PATH}") chrome_options.add_argument("--headless") chrome_options.add_argument("--disable-gpu") chrome_options.add_argument("--no-sandbox") chrome_options.add_argument("--disable-dev-shm-usage") with webdriver.Chrome(service=Service(ChromeDriverManager().install()), options=chrome_options) as driver:

Seeing as the mpu6050 is obsolete, any recommendations for a more accurate accelerometer module?

Some important information: With current v1.24 of microython firmware it is needed to disable first the station interface (used to connect the Raspberry to other AP) to work with AP interface. In this code just add the following lines before ap declaration: sta_if = network.WLAN(network.STA_IF) sta_if.active(False) Otherwise the Raspberry does not receive or send anything.

hello! I think you are great. I am using your instructables tutorial to help me with my BMP180 sensor, but the code you have linked to is no longer public on your git. Is it gone forever, or is there any way you could post another link, so that I can view and pull from it. thank you so much! I am currently trying to build a satellite

is there a Part 4?, I'm having issues like you said, I can't download the libraries

I've followed this carefully - but I never get anything asking for the password. So it doesn't connect

You just made me pass a test at college

Thanks!

Please clarify the units of the gyroscope values

Super❤🎉😊

Raspberry pi OS is based on Debian Bookworm this is the latests, it hasn't been called Raspian since Debian Stretch was replaced with Debian Buster ( raspberry pi OS) in 2020....... this may not work as bookworm has a new camera pipeline

can the visualization on screen be a 3d model that I can import from my laptop

As of today, I'm not sure if MicroPico supports Linux and Pico2 - i cannot create project, but I can upload a single file. Now I found out there is official "Raspberry Pi Pico" extension that seem to support both MicroPython and C++.

I'm doing this! Thanks! I do like the bite-sized videos. Much easier to actually go into the "lab" and work on.

Cool.

Thanks for posting the missing line. I used ap.ifconfig(('192.168.130.1', '255.255.255.0', '192.168.1.1', '9.9.9.9')) It said it was broadcasting as 130.1 as I wanted, but then reverted back to the 4.1 (not what I want)

Thank you! My aruino nano is just "arduino nano", not "every nano". Tested and worked for me.

should i need to connect usb to ttl connector to stm after uploading the code ?

i am facing an issue over here @2:54. i am not able see any inteface for camera (but, it does show other interfaces like SSH, I2C, Raspberry pi connect, SPI, etc), i use raspberry pi 4B.

Thanks!

I will gladly pay for anyone who can get MQTT working with my micropython v1.23 working with AWS Iot. Its weird, there is no ussl with this version and it throws errors. Cannot figure this out!

Can you make 2 VM raspberry. One is act like client and the other one is a proxy server squid

what if i want to upload image

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??
