Project Description: This is my project, its about a secure object-oriented system lock, which it scans object, you can choose to add that object with a button and it will automatically lock it as a key(3-object-key), and then you can test if you re-scan the correct object with the correct order, you won, but if not, you lost. So this is made for security systems to use object oriented-key so that it may be more secure, and in this one, it uses object detection, 10 possible objects, and 3 possible input Making it have 3^10 or 59049 combinations possible.
