As always, links are given below in the video description.Now extract downloaded folder.Open "Rfid Login" code.Click on "sketch" then "include library", "Add ZIP Library.." browse to "Libraries"in Rfid_login folder select rfid_master.zip.Put Your password of windows/facebook or what you want to unlock.Select arduino's serial port. Then upload the sketchNext you have to Install flip softwareAnd after that Open computer ManagementConnect reset and ground pin as shownLook for "Unknown devices" in computer management.
