simple question: is there a way to know which sensors are connected to a Raspberry Pi? I.e., I'm in the Raspberry command line and want to know what's connected to it.

When I watch it on the internet, the code in the image proceeds without error when run, but it gives me such an output. What could be the reason for this?
I am using Raspberry Pi 3B+ model.
I'm currently working with Kinect v2. I can do all sort of stuff on PC with it. What I want to do next is, to get the data I want on PC and control the Raspberry Pi with that data (for example, I will move the Pi with motors when I tilt my head to right). I have sorted out the motors and everything but I just don't know how to use that tracking data I have on PC to control the Pi.
I hope the question makes sense, i'm just extremely new to both Pi and Kinect.
Thanks for the help!
The first step is to choose the bus that will connect the
PC to the Raspberry PI.
Your options are:
Serial bus: Pi Serial tutorial,USB Serial to Pi cable
Network Socket (cable/wifi): Socket client/server c++ examples
i2c: i2c windows PC, Configuring i2c on Pi
I believe that the i2c or serial bus will be the easiest to start
with. But in the end all 3 options need to set up the connection, and send and receive bytes / byteArrays.
Since MQ-3 sensor provides analog output, we have got MCP 3008. We tried to make the connections with Raspberry pi 3 using the connections from MQ-2 sensor available online. Nothing works! Need help to interface MQ 3 with Raspberry pi 3 for detecting Alcohol Level
this link is best to interface analog sensor with raspberry pi
https://tutorials-raspberrypi.com/configure-and-read-out-the-raspberry-pi-gas-sensor-mq-x/
use this link but if you want use analog sensor with raspberry pi so you need another ADC module or another chip like PIC , ATMEGA 32
I need help around creating a circuit of more than 100 ultrasonic sensors connected with a single Raspberry Pi(running on Windows 10 IoT core).
When IoT device sends request for Information(broadcast) to these sensors, response from all the sensors should go back to the Raspberry Pi. Then I should be able recognise the response sent by each sensor in my program.
I have studied a bit about I2C pins but not sure how to use it with my very limited electronics knowledge.
I'd like to use the a Grove RGB LCD on a raspberry Pi. I would like to plug it directly with minimal circuitry.
It's a cheap RGB LCD that use I2C. There's raspberry pi librairies (Python and C)... but it's supposed to be plugged to a Grove Pi wich is more expensive but you don't have to.
Has anyone done that already ?
The RGB LCD uses a 5V rail. The Raspberry Pi uses a 3V3 rail. If you're going to connect them, you'll need a level converter chip in between them. The GrovePi provides the level conversion, but if you're not going to use the GrovePi for the Raspberry Pi, you'll need to find your own chip or you risk damaging both the Raspberry Pi and the LCD.
