How to interface this no nc c switch with arduino

@LarryD

When debugging code, add Serial print statements at strategic places to print variables to the serial monitor.

This allows you to check these variable values and confirm they are what you think they are.

Like this ?
const int switch = 7;
then
pinMode(switch, INPUT_PULLUP);
If not please explain more because i still newbie

@LarryD

Always tell us what didn’t work.

I men the switch didn't work with my project code
