Rasp p3 + arduino

Who helps me send temperature probe values ​​from an arduino to raspbarry ?!

a quick google search gave this https://oscarliang.com/connect-raspberry-pi-and-arduino-usb-cable/

they are not close but they are all far apart and connected either wifi or ethernet

you cant send a value. what are you trying do?

Are you using Cayenne to display the data? If so you can upload a sketch directly to the Arduino devices and you do not need to worry about the Raspberry pi. If you really want to continue down that path see my post here.
