I'm not understanding this joystick. I wrote this program to identify each movement, but it doesn't work the way I expected. In the serial monitor I see a number flip from 6 to 7 pressing a button on the joystick. I have 4 pins plugged into PWR and 3 pins plugged into GND as the diagram shows. What am I doing wrong?

Purpose: Test each direction of the joystick to figure out
which pin relates to it. Print the pin # in the serial monitor
and then you'll know by the direction your moving the joystick
which pin correlates to it.
