How to Run a Script on Startup for Raspberry Pi // EASY
This is great thank you. I need a static bulb just wasn't sure which pins to use. Next objective for me is to try to get a potentiometer working on pi 4. Trying to create a racing arcade cab.
I have seen over 100 video Let me say you are the best compare to other but ssh command doesnt work . I download putty would mind explain it pls .😢
Thank you for explaining this in a way that actually makes sense (and works) for me.
Is the Alexa Voice Service not longer available or it ist in a Relaunch phase?
This isn't working for me. I don't know why, I keep getting error messages and no voltages from the 3.3v and 5v pins either
Update: I did something noob on my RPi5
hello, at 1.23 it doesn't works, an error message occurs : Permission Denied
when i connect my pi, i only see a rainbow square
following this tutorial and my frame is just dark. any ideas?
not working as i'm using pynput library ,how to solve this issue?
how dose code in thonny access the opencv when its in its enviroment
its take 4 hours on RPI 2 to installation of opencv
Thank you so much this really helped me to get started with raspberry pi!
Brilliant! Great video+explanation+presentation! Thank you for sharing! Well done mate - NEW SUB 🙏🏻
i am not able to register the device , it throws a error "Reached limit on number of clients in this project.Try in a new project. there is no option for upgrade also could you please help with this "
Yes I do get the same error I think the Google Assistant SDK is not working now. "Conversational Actions were deprecated on June 13, 2023. For more information, see Conversational Actions sunset."
Can you also add a command there to change to activate another env?
i have been trying to do this using ip for a while but my fucking router wont let me so its super fucking annoying but thankyou so much for this didn't realise i didnt need the ip thanks man
Thanks a lot,appreciate it
how I off this script, when I run this method my program dosn't work. My GPIO is busy and program dosn't work
Thanks, very informative!
at 8:00, shouldn't you use min() in to avoid overflow issue? for example if img[i, j] is 160, then max(254, 160*2) would give you 320.
I think you may be correct
Got Trouble in Host key verification !!!!! Just simply update the SSH known host by typing ssh-keygen -R [hostname] in this case the hostname is "raspberrypi"
I’m Learning Python and raspberry pi once I’ve got Python. So excited for my journey 🎉
Great video, thanks!
At least you should have given explanation about what the python script does and given a look at the commandes. Unless the video is not informative at all.
I'm trying to read an ADC with a rasp 4 but first I need to understand the basics, thnks for the video!!
Interesting but can this be done in esp32 camera module?
Thanks a lot man.. worked on the first try... really thank you..
Amazing video bro! It was really helpful!
don't do it bro. put the hammer down!
How can i install lib-jasper it said that "unable to locate"
I am using a 1 tb m.2 ssd to put Ubuntu on but nothing comes up when I turn on the pi. I am using a raspberry pi4b.
love you man
Should we insert sd card in to the SD card slot of raspberry pi?
im getting stuck on the register model step, everytime I try to register a model, it throws a error "Reached limit on number of clients in this project.Try in a new project."
Yes I do get the same error I think the Google Assistant SDK is not working now. "Conversational Actions were deprecated on June 13, 2023. For more information, see Conversational Actions sunset."
Thx for this great explanation!
Can you do this with lan and not wifi?
do i need to have billing account for create and registered model
Yes I do get the same error I think the Google Assistant SDK is not working now. "Conversational Actions were deprecated on June 13, 2023. For more information, see Conversational Actions sunset."
Noob here. I followed the previous videos but all I want to do is be able to see a webcam on the PC. Using nano I created this same file but when I try to run it, I get the following error message. qt.qpa.xcb: could not connect to display qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/pi/project/env/lib/python3.11/site-packages/cv2/qt/plugins" even though it was found. This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: xcb.
mines keeps saying cannot currently show desktop. why?
Great vibe, really good tutorial for people starting with Raspberry Pi and input/output. Keep it up, you are a natural!
this killed my pi. how to stop it from running? I was playing a video in full screen and now is impossible to access the terminal.
wow did not expect to find the biking legend when I clicked on this tutorial
That was clear and straightforward, thank you.
Absolute life saver, why it no other tutorial this simple??
I've been trying to attempt this tutorial. I'm using a 8 GB RAM raspberry pi on a 250GB SD card and the interface keeps on crashing on me. And I'm having storage issues due to the size of Tensor Flow and OpenCV. Any suggestions on how to mitigate this issue?
i enjoyed.i need learn lot for my job.i work in security gurd in iran :D
That's awesome. Thank you! And how do I make it return to the normal boot?
Hi, did you find the way? IF yes please tell me how you do this, i didnt try it yet, cause i am scared of broken my pi
OK, now my RPI-Pico immediately starts a game. When someone wants to get out of the game and go back to, say, the Thonny window, how do they do that? Include a pushbutton-checking routine that quits the game loop? Use a keyboard input to end the game? I want the gane to run again and again unless I do something to exit it. Thanks. Very good tutorial.
How to print log file ?
Just missing the heavy metal background music 👍
