STC89C52做的学习型遥控器，可存八个红外遥控信息，只要再把按键用定时器中断2完成就可以用于商业生产了-Do STC89C52 learning remote control, infrared remote control can keep eight of information, as long as the button and then use Timer 2 interrupt can be completed for commercial production of the

实现9层电梯控制 功能如下：1，先假设没上楼之前，楼层运行看不到(没图形），可以当做随机看待。 2。当在某层按电梯开关后，在屏幕显示电梯停到该指定楼层的图形状态。 3。随后可以按想去的楼层，在屏幕显示电梯运动过程，， 4，可选择是否还执行本程序（坐电梯）-9 realize elevator control layer functions as follows: 1, first assume that no public housing, before running the floor can not see (no graphics) can be viewed as random. 2. When a layer switch by the elevator, the elevator stopped on the screen display to the graphics state designated floors. 3. Then may want to go to the floor, in the screen display elevator movement process, 4, can choose whether the implementation of this program (elevator)

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

本次设计的温度计采用HT46RB50 微控制器IC，HT46RB50 的AD 口外接一热敏电阻，通过 AD 读回的电压计算出热敏电阻阻值的变化，从而实现侦测外界温度的功能。HT46RB50 通 过USB 将侦测到的温度值传入PC 机的温度显示接口中显示。 本次设计的USB 使用操作系统提供的USB HID 设备类驱动程序。 • 采用USB 控制传输向HT46RB50 发送资料 • 采用USB 中断传输接收HT46RB50 传回的资料-The design of the thermometer used HT46RB50 microcontroller IC, HT46RB50 of AD external mouth of a thermistor, through the AD read-back voltage to calculate the changes in thermistor resistance in order to achieve the function to detect the outside temperature. HT46RB50 through the USB will be detected by the temperature of the temperature of incoming PC-display interface to display. The USB to use the operating system designed to provide the USB HID device class driver.
