2017-314、51随机数产生器设计-LCD1602-KEY

本设计由STC89C52单片机电路+1602液晶显示电路+按键电路+电源电路组成。

1、系统有10个数组(每个数组有1个4位密码)，对应不同的密码(密码是4位)，如果按键按下(10个按键代表1234567890)，按下确认按键后，如果输入密码(4位密码)在10个数组中，则液晶显示：PassWord Right。否则就显示：PassWord Error

程序密码表：

unsigned char mima01[4]={1,2,3,4}; //对应10组密码

unsigned char mima02[4]={4,5,6,7};

unsigned char mima03[4]={8,9,0,1};

unsigned char mima04[4]={1,5,5,6};

unsigned char mima05[4]={0,3,5,7};

unsigned char mima06[4]={9,8,2,2};

unsigned char mima07[4]={5,2,6,8};

unsigned char mima08[4]={3,3,3,0};

unsigned char mima09[4]={3,5,7,9};

unsigned char mima10[4]={0,0,4,5};
