It depends.  If you don’t use your credit card in a particular month, but have an outstanding balance, then yes, you will need to make a payment on your credit card account.  When you get your statement it will reflect the minimum payment due, which will include the interest assessed on your outstanding balance.  On the other hand, if the balance on your credit card account was zero at the beginning of your billing cycle and then zero at the close, you will not be required to pay anything on your account.  Additionally, even if you don’t use your credit card in a particular month, as long as you are current on your payments, your account will still report to the three major credit bureaus as being in good standing.
