AT89C52 Microcontroller-Based Electronic Locks Design

Abstract:

This paper describes a small, low cost, functional and practical design of electronic locks. The locks to AT89C52 microcontroller as the core, mainly composed of the microcontroller, LED digital tubes and relays. And through the C programming language, complete the functions of unlock password, prompt an error, LED display and timing, and even to achieve a function that when power-down the lock can remember passwords.
