SafetyLock: a Smart Lock Made With Raspberry Pi (Fingerprint and RFID)

Have you ever wanted a more accessible way to secure your house? If so, this is the solution for you!
I made SafetyLock, this is a lock that can be opened with your fingerprint, a RFID badge and even through a website. Thanks to this concept you will always know who entered your home at what time of the day, you’ll also see how many times someone stepped in front of your door that day.

For my project i used multiple parts that i will be listing below, I’ll also add the excel file with all the corresponding prices of the components as also the websites from which I ordered them.
