六位电子密码锁
采用89s52(51,52都可),4*4键盘,六个数码管,74ls04(位选),573(8D锁存器)。
说明:P2---数据(接573)―――(接数码管)
P1---位选 ---(按74ls04)
P0--4*4键盘
密码一次性设置(编程时写入的)
电路简单,此源程序仅供初学者学习,可自行扩展密码模块(加24C02)。
编绎软件为wave
-six electronic password lock used 89s52 (can be 51, 52), 4* 4 keyboard, six digital control, 74ls04 (EC), 573 (8D latches). Note : P2-- Data (573 )---( access digital access control) P1 Choice------ (74ls04 ) P0-- 4* 4 keyboard set up a one-time password (into programming) circuit is simple, This program is for beginners learning will be able to expand password module (CO2 plus 24). Sounds series software wave
