hello good day,
we make a door lock project based on RFID, our problem is were having trouble on how to get line by line inside the text file… Were using SD card as mass storage.
swipe the card then check if the ID exist inside the textfile (users.txt).
if yes , get the ID(ID of the card) and name inside the textfile from users.txt —>this is our problem
then, place in logs.text…
unlock the door
if no, it remains lock.
please respect , thank you. Godbless
