Rpi-rf 433mhz receiver transmitter
Hello guys, have you ever tried to communicate with the 433mhz receiver and transmitter via raspberrypi 4? It seems that the receiver is not receiving the signals. I tried the same application with Arduino and it actually worked.
Any ideas why I can't receive the signals?
I use python3 rpi-rf package for this.
The wiring between the pi and the transceiver is fine, I doubled check it.

Voice Assistant Robot
Hey guys, I am currently building a companion robot for a school competition and am really stumped on how to get started with hardware. I am using a pi 4 model b, and I need the bot to preform voice recognition and face recognition so I was planning on using a USB webcam. I will also need speakers and a display that will serve as the bots face. Do you guys have any suggestions? It will be very similar to the robot Buddy. Thank you so much!

GPIO output on RPI5 not working
I've been trying to connect and control an LED on a new raspberry PI 5 using GPIO and a breadboard. I connected the LED with a 220Ω resistor and I'm quite sure it's not burnt, connecting it to a 5V or 3.3V pin lights it up properly. When I try to connect it to a GPIO pin, it's either preset to either high or low and stuck there, no matter what. I tried using the gpiod package on python3, some libraries in rust, and the gpioset command on the command line, using gpioinfo and gpiofind to find the correct pin numbers. I also checked to make sure I have the correct permissions, and ran those with sudo. The LED stays on or off no matter what. In GPIO18 for example it was consistently off, in GPIO21 it was consistently on. I can't fathom what I'm doing wrong.

Setting up Home Assistant using M.2 SATA SSD
Hello!
I've just purchased my first Pi along with an Argon One case and an M.2 SATA SSD.
I'm watching a video on the Home Assistant setup to get a bit of extra knowledge before they arrive and noticed I may be missing a couple of things...
I don't have an M.2 SSD to USB adapter to install the Home Assistant OS using the Pi Imager - Will this be required, or can I install the OS on the PI itself?
I also didn't purchase an SD card, the video I'm watching uses an SD card to install USB Boot so the OS will boot from the SSD instead of the SD card- Do I need to purchase a good SD card for this, or will the cheapest SD card I can find on Amazon be okay for this step?
Thanks 🙂

VNC connection refused
Hello guys, I'm trying to setup VNC and connect to PI. It is worth mentioning that I already could connect to PI through VNC. Then I accidentally powered down the PI and since then I could'nt enter conncet again.
I downloaded again OS (64-bit, bullseye, with desktop).
I connect via SSH to the PI [btw I couldn't connect to the PI with username@hostname, but only with username@ip, I don't know if its relevant]
I setup VNC connection in the raspi-config and resolution but cant connect via VNC.
Any help would be helpful, Thank you! 🙂

Screen Mirroring - Windows Not Duplicating
I've got a Raspberry Pi 4B and two monitors.
In the Screen Layout Editor, I have both monitors set to the same resolution and overlaid on top of each other.
The mouse, desktop background, and desktop icons are all mirroring properly across both monitors.
However, any windows open on my primary monitor (chromium, system settings, etc.) don't show on the secondary monitor unless the window is dragged around with the mouse. If dragging a window, it appears on both monitors. When the dragging stops, the window disappears on the secondary monitor.
I've looked through a bunch of forum posts, but no one seems to have this kind of problem.
Any advice on how to proceed?

I purchased a pi 5 8GB. Looking to go to Arcade 15khz monitor
I know there are several options for previous pi models and the 5 is pretty new. In a few months after I am done with the woodworking on my arcade cabinet, I am looking to use the p5. I am not seeing some of the options for 15khz say they are compabitble with the pi 5. I also would like know what what the best USB encoders might be to get my controls working and coin mechs to register with MAME. Looking for suggestions.

waveshare white screen rpi zero w w
(I did research but really struggling right now as I've tried different solutions and no luck + I'm a noob)
I purchased this screen and buttons for my Raspberry pi zero 2 w:
https://www.waveshare.com/wiki/1.44inch_LCD_HAT
The problem I have is that the screen is always white. I sometimes have to jiggle it a little to get it to turn on, I have to use headers as they aren't soldered to the board.
I know the documention is a tad outdated because their demo script is in python2. But the demo for both c and python just show a white screen.
I have tried many different OS' of different versions of PiOS, including a 2019 version of raspian (which doesn't even boot on the zero 2 w, it just displays the rainbow screen and does nothing).
All I want to do is get the demo working so I can at very least try the rest of the documentation and get the desktop showing on the mini display.
I contacted waveshares support who told me to use bullseye version of raspbian, I did just that and I got the same result, they also copy and pasted some bits of the guide ok the wiki including instructions on how to I stall python 2, despite me telling them the board and using after they asked me.
Any advice?

Help choosing the right Pi!
Hi all 👋
I'm looking to get started with Home Assistant! I've done a bit of research and I think I know what I want, but I'm seeing a lot of conflicting posts online around the do's and don'ts, so I was hoping to get some opinions on what to buy to get started 😊
I'd like to take the Raspberry Pi route, as I like the DIY aspect of it, but this is possibly the area that confuses me the most.
If I were to purchase a Pi 4 Model B -
- Is there a notable performance benefit to the 8GB version over the 4GB version?
- Is it actually a bad idea to use an SD card? Or will I be better off purchasing an SSD?
- Is it worthwhile adding a fan?
- Are kits worth buying, or is it just as good to buy everything individually?
Sorry if any of these questions are stupid, just wanting to make sure I get off to the best start!!
Thank you!! 😄
