I want to make object detection application with raspberry pi 4 4gb Ram.The problem is that I dont be sure which object detection model I should use. I mean which one is suitable for raspberry pi 4. Besides , I dont have a USB accelerator stick.
Mobilenet v1 is quite fast on pi 4, look at the below blogpost for more details -

is there any way to use the ADS1115 with a raspberry pi pico?, I'm in the middle of a project where I need 4 analog inputs but the pico only has 3, I'm using circuit python btw... any help is appreciated
I found this on github ads1115 and raspberry pi pico i hope it will work for your project!
You can also watch the tutorial on youtube here
So i used this library. The ADS1115 just connects to a i2c port and your off to go. One thing to note that you will need to do single shots for each adc read. You can only do continues sampling on one channel at a time.

Want to run a small custom model on a raspberry pi, what architecture would run inference the fastest given the limited power of a pi?
I'm designing a device to use this PI and need to know how much current to allocate for it. It will only be driving a single HDMI monitor, using a UART, and a hat board driven from the OTG USB.
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'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.
