- 本系统以AT89C51为控制核心，由矩阵键盘输入，LED倒计时、交通灯显示等模块组成，模拟了一个交通灯控制系统。系统除基本交通灯功能外，还具有通行时间手动设置、可倒计时显示、急车强行通过、状态切换等相关功能。包括报告提供。-AT89C51 for the control of the system core, from the matrix keyboard input, LED countdown, traffic lights displays modules, to simulate a
HT46R24cewen
- 本系统利用集成智能温度传感器测量温度，采用光纤传输温度信号。系统由单片机（HT46R24）控制温度传感器（DS18B20）的温度采集。当有采集温度的指令的时候，才启动温度传感器并采回其数据，在没有进行温度采集的时候，将通过抬高温度传感器的地，关断其工作电源，如此可以降低系统的功耗。系统将每一次采集回来的数据与前一次的数据比较，若温度变化超限或温升超标，立即发送上述温度值；否则，累加到采集了一定的次数，再向主机发送最新温度值。-The system uses an integrated smart
ISD1760
- 通过PIC16F877主控芯片操作ISD1760语音芯片，可以通过手动录音以后实现录音地址的提取。地址计算方法包含在注释中，音质好，可以满足大部分的需求。-PIC16F877 chip operations through the Master ISD1760 voice chip, can be achieved by manually recording after the recording address of the extract. Address calculation metho
PWMtiaoguang
- 利用定时器产生PWM，控制LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象-The use of timers generate PWM, control the LED light from bright to poverty, from the gradual eradication of the light changes, the phenomenon that is dimming
