Infrared-detection-devices
- 本设计主要由红外线传感器、信号放大电路、电压比较器、延时电路、音响报警电路、开机延时电路和电源电路组成。人体时时刻刻都在发射人眼不可见的红外波,但是可以被红外线传感器Q74接收,只是这个信号很小。经过前级三极管放大和后级运算放大器LM358放大之后,信号放大到足够大。在电压比较器LM393和延时电路的控制下,能够很好的实现,当有人出现在一定感应范围内时,探测防盗器自动报警。-The design mainly by infrared sensors, signal amplifier, volt

SOUND
- 蜂鸣器在单片机上的应用,C语言源码,Keil uVision3工程文件,附原理图及说明学习文档 蜂鸣器的正极性的一端联接到5V电源上面,另一端联接到三极管的集电极,三极管的基级由单片机的P1.5管脚通过一个与非门来控制,当P1.5管脚为低时,与非门输出高电平,三极管导通,这样蜂鸣器的电流形成回路,发出声音。当P1.5管脚为高时,与非门输出低电平,三极管截止,蜂鸣器不发出声音。在这里与非门是作为非门来用的,这里采用一个非门的作用是为了防止系统上电时峰鸣器发出声音,以为系统复位以后,I/O
LM324LM339
- 用不同的元件,做一样的三角振荡波形,上面的用示波器测得是差不多的波形!LM339与LM324是很相近的元件,我一直用LM339做振荡,没用过LM324做振荡.但有于实际需要用振荡,又要用信号放大.在电路就需要同时使用这两个蕊,为了节约成本,想了下,LM324也可以做振荡,只是多一个三极管.这样就可少一个蕊了,-With different components, so as Sasser triangular shape, the above measured using oscilloscop
