Hello, I need help with a question, I want to make sure that when entering a QR code that represents an object, it is registered in a string that it is ´´available´´, and after showing the same QR again, it marks that it is ´´in use ´´, and finally when entering the QR a third time, mark that it is ´´available´´ again, what I look for is for it to be as simple and practical as possible.
I am attaching my project in labview so someone can give me a suggestion or help
