Measuring voltage on arduino pin

Hi guys.

I am new to using the arduino. I compiled a code that outputs a 5V value based on a given input. I would like to test that this code is working correctly by measuring the voltage on the pin. I’m trying to hook up the arduino pin to my multimeter, but I am unsure which pin I need to connect to GND on my multimeter. It seems there are a few ground pins on the arduino.

All arduino shield ground pins are the same electrically, use whichever one is most convenient for you.
