(The password lock of this design is unlocked by 8-digit password lock. The electronic password lock gives an alarm by rxled, and judges whether the password is correct or not by alarm. After the digital password is input, the code circuit and the latch circuit are used to save the password, so as to compare the passwords. If the password is not input correctly, the alarm rings for 3 seconds. Ring once after the password is entered correctly.)
