RPI 3 B+ Not working. Only red light.
I powered my RPI 3 B+ with a Fast Wall Charger, Model: Q5003-US, Input: AC 100-240V.50/50Hz.0.5A Max, Output: DC 3.6-6V=3A, 6-9V=2A, 9-12V=1.5A
I did some research and the RPI only needs 5V,2.5A... So, I think I fried it. But if that was the case, then why is the red light still working?
I re-flashed the micro-sd, nothing. I used another micro-sd, nothing. I went back the the 5V,2A head and nothing works.

no module named picamera error
I recently formatted my raspberry pi 4 using the official website imager to 32 bit os
I face these errors when trying to run my code
I have already tried:
1. going into raspi-config (there's no option to enable camera, even inside the interface option)
2. update and full upgrade
3. pip install picamera
What should I do?

Terminate code mid way through with a button press
Hi all, I have the following code (hopefully this is formatted correctly in discord)
import time
import board
import digitalio
import usb_hid
import sys
from adafruit_hid.keyboard import Keyboard
from adafruit_hid.keycode import Keycode
btn1_pin = (board.GP16)
btn2_pin = (board.GP15)
# Set up the button
btn1 = digitalio.DigitalInOut(btn1_pin)
btn1.direction = digitalio.Direction.INPUT
btn1.pull = digitalio.Pull.DOWN
btn2 = digitalio.DigitalInOut(btn2_pin)
btn2.direction = digitalio.Direction.INPUT
btn2.pull = digitalio.Pull.DOWN
keyboard = Keyboard(usb_hid.devices)
while True:
if btn1.value:
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
keyboard.send(Keycode.A)
time.sleep(01)
if btn2.value:
keyboard.releaseall()
(Eventually the A keycodes will be swapped for scroll down arrow commands to I can scroll up and down a page) What I'm finding impossible to do is to stop the code mid way though with the press of btn2. is there a way to do this?
thanks.

15-30 second delayed "Live" Video playback
Hey all, just wondering if this would be possible. I have never used a raspberry pi properly before and have 0 knowledge on them or their capabilities just for a bit of information.
I need a way to take a live video feed from a camera or webcam, and play it back with a 15-30 second delay on an external monitor, this would need to be able to run with no internet connection and be robust enough to run for 6 hours per day, 7 days a week, 365 days a year. I'm UK based if that is of any help or hinderance. Thank you all in advance

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! 🙂
