Hello everyone, I have a doubt. Use the arduino to get analog signal and send it to the raspberry is better than just use the raspberry to get this type of signal?

Hi,

Maybe not better in all cases but possibly easier as Arduino USB output can be connected into a P3 3 USB port.

If you have access to Chinese Arduino Nano clones they can be ordered from the UK from £1.50 including postage.

I've got one talking to a sensor and sending the data serially to a Raspberry Pi 3B+.

Regards

RPis have no analogue inputs. Whether it is better to add an ADC to the RPi or use the ADC capability of an Arduino depends on many factors, none of which you have mentioned.
