Need help connecting the MKR Connector Carrier to Arduino Uno

Hello!

I'm super new to Arduino, and I got an MKR Connector Carrier so that I could more easily connect sensors to the Uno. I have put several hours (not even joking, hours) into researching everywhere I could to figure out how to attach the MKR Connector Carrier to the Arduino Uno but I can't find anything. Would I just need to connect the 5V and GND pins on both?

As for connecting sensors to the MKR Connector Carrier: If I fit a sensor into the A0 port, how would I access that with the analogRead() function? Would I need to make a connection between the A0 pins on the Uno and the Carrier?

Sorry if my questions are the dumbest things you've ever heard -- I'm still trying to get a hang of this. Also, apologies if this post is in the wrong section.

Thanks so much!!!

I have no direct experience with that shield, but it is not made to connect with an Uno. You will have to make the connections with jumpers. Connect 5V and ground from the shield to the Uno. Then connect any pins that you want to use. So if you plug a sensor into the A0 socket, connect the A0 pin from the Uno to A0 on the shield header. Yes, use analogRead() to read an analog pin.
