Abstract

This requirement is designed to use electronic devices of an electronic lock control circuit to make it enter the correct code, the lock opens automatically; when the input password is incorrect when the automatic alarm, and reset the circuit, and the use of some additional circuitry to ensure the circuit normal work, so that the circuit has a very high safety factor. In this paper, the electronic lock of the basic knowledge of a detailed explanation, and then a detailed analysis of the electronic code lock works, the role of the various components.
