某公司安装了电子门,要设计门禁系统:
公司的雇员可以凭借密码、胸卡或指纹进入公司
计算机根据雇员的验证方式对其身份进行验证
管理员在监控室可以通过按钮直接开启电子门
访客可以按门铃请求进入,由管理员为其放行
管理员可以为新职员设置密码
(A company to install an electronic gate, to design access control systems: the company' s employees can rely on passwords, badges or finger into the company computer, authentication of the employee to verify their identity can be an administrator in the control room directly through the button to open electronic gates that visitors can rang the doorbell of the request to enter an administrator can be released by the administrator of its staff to set a password for the new)

MCU51_LXY
51单片机LED流星雨灯,原理:
利用PWM来模似流星雨:将亮度等级分为8个
,通过改变每一组LED的亮度来达到流星雨效果。因为流星雨是前面亮后面越来越暗,就像一条龙一样,拖着尾巴过来。(51 single LED meteor light, principle: the use PWM to die like a meteor shower: The brightness level is divided into eight, each group by changing the brightness of the LED to achieve the effect of the meteor shower. Because meteor shower is getting back in front of bright dark, like one-stop, like dragging tail over.)

atcmd
GSM模块AT命令组装和AT命令响应解析程序。实现了自动组装标准AT命令并发送到GSM模块,同时可以提取GSM模块输出的所有AT命令,同时实现了大量AT命令响应的解析工作。主要的过程采用了Contiki的进程模型。(Making and parsing routine for AT commands of GSM module. It can automatically make standard AT commands and sent it to GSM module, while it can get all the AT commands sending GSM module, and analysis a large number of AT command responses. The main process uses a process model of Contiki.)
