Description: bascom-avr专业AVR密码锁项目：
该项目是提高AVR的数字密码锁的版本。在这个项目中，你可以改变从系统菜单中的8位数字的密码。也有一个经理的控制面板，一个4位数的PIN码保护，以保护其他人访问这个安全区。这个PIN码是与控制面板多变。这个版本的另一个优势是一个定时的安全级别，当你进入一个不正确的密码3次，系统将约5分钟待机！所有的密码保存在EEPROM存储器。最新的功能真的是changeabe输出 触发器或定时从1到255秒。-Professional AVR Code Lock Project:
This project is improved version of Digital AVR Code Lock. in this project you can change 8 digit password from system menus. also there are a manager control panel that protect with a 4 digit pin code to preserve other people access to this security zone. this pin code is changeable with control panel too. another advantage of this version is a timed security level when you enter a incorrect password for 3 time the system will be standby for about 5 minute! all password saved on EEPROM memory. latest feature is changeabe realy output flip flop or timed from 1 to 255 second.
