Description: 超声测距,外围用LM567音频解码器来锁定接受的声波频率，程序里用的是40KHZ,发送200ms，然后等待接受进行中断。里面只有程序，外围电路很简单，注意要把信号放大。-Ultrasonic ranging, external LM567 audio decoder to use to lock in acceptable sound wave frequency, the program inside using a 40KHZ, send 200ms, and then waiting for interrupt. Only inside the program, the external circuit is very simple, pay attention to make signal amplification.

Description: 电路中使用了锁相环音频译码器LM567。LM567是一种模拟与数字电路组合器件，其电路内部有一个矩形波发生器，矩形波的频率由5、6脚外接的R、C值决定。输入信号从3脚进入LM567后，与内部矩形波进行比较，若信号相位一致，则8脚输出低电平，否则输出高电平。8脚是集电极开路输出，使用时必须外接上拉电阻。
将LM567第5脚上幅值约为4V的标准矩形波，通过R1引至三极管VT1的基极，使接在VT1发射极的红外线发射管导通并向周围空间发出调制红外光。-PLL circuit used in the audio decoder LM567. LM567 is a combination of analog and digital circuit components, the circuit inside a rectangular wave generator, square wave frequency from 5,6 feet external R, C values of the decision. Input signals from 3 feet into the LM567, the comparison with the internal rectangular wave, if the same signal phase, the 8-pin output low, otherwise the output is high. 8-pin is open collector output, use an external pull-up resistor must be. Amplitude of the LM567 is approximately 5 feet, the standard rectangular wave 4V, cited by R1 to the base of transistor VT1, so connected to the VT1 launch tube infrared emitter to turn the space surrounding the issue of modulation infrared light.
