Based on MCU
基于单片机控制的电子密码锁
摘要:本系统由单片机系统、矩阵键盘、LED显示和报警系统组成。系统能完成开锁、超时报警、超次锁定、管理员解密、修改用户密码基本的密码锁的功能。除上述基本的密码锁功能外,还具有调电存储、声光提示等功能,依据实际的情况还可以添加遥控功
-Based on MCU-controlled electronic code locks Abstract: This system consists of single-chip microcomputer system, matrix keyboard, LED display and alarm system. System to complete the unlock, overtime alarm, lock超次, administrators decrypt, modify the user s password locks the basic functions. In addition to the above basic code lock function, but also has a transfer electric storage, sound and light features such as tips, according to the actual situation can also add a remote control reactive

伟福LAB2000单片机仿真系统直流电机控制:利用实验仪上的D/A变换电路,输出-8V至+8V电压,控制直流电机。改变输出电.压值,改变电机转速,用8255 的PB.0 读回脉冲计数,计算电机转速。在电压允许范围内,直流电机的转速随着电压的升高而加快,若加上的电压为负电压,则电机会反向旋转。本实验仪的D/A变换可输出-8V到+8V的电压,将电压经驱动后加在直流电机上,使其运转。通过单片机输出数据到D/A变换电路,控制电压的高低和正负,观察电机的旋转情况。
在电机转盘上安装一个小磁芯,用霍尔元件感应电机转速,用单片机控制8255读回感应脉冲,从而测算出电机的转速。
