Hello, I am writing some code that will function as a RFID door system. At the beginning of the program, I want to define the list/array/vector and give it 6 strings. These strings are the codes of the acceptable ID's that will allow the door to be unlocked. So in the program it scans the list, and also can add a new string to the list if a new ID card wants to be added.
I have had trouble using arrays, and I know that vectors can be much easier. However, I've found that arduino doesn't support vectors? Anyone have any experience with vectors? Or using a list of strings in the past?
