This book was written by Michael Margolis with Nick Weldin to help you explore the
amazing things you can do with Arduino.
Arduino is a family of microcontrollers (tiny computers) and a software creation envi-
ronment that makes it easy for you to create programs (called sketches) that can interact
with the physical world. Things you make with Arduino can sense and respond to
touch, SOUND, position, heat, and light. This type of technology, often referred to as
physical computing, is used in all kinds of things, from the iPhone to automobile elec-
tronics systems. Arduino makes it possible for anyone—even people with no program-
ming or electronics experience—to use this rich and complex technology.

超聲波換能器作為一種實(shí)用的檢測(cè)手段，能實(shí)現(xiàn)聲波所攜帶的信息和電能之間轉(zhuǎn)換。它的性能優(yōu)良，價(jià)格低廉，操作方便，易于調(diào)試，因此在工農(nóng)業(yè)生產(chǎn)中發(fā)揮著重要的作用。但目前換能器驅(qū)動(dòng)電路的發(fā)射頻率多為40 kHz，本文針對(duì)1 MHz的超聲波換能器電路進(jìn)行了設(shè)計(jì)，主要介紹了它的發(fā)射驅(qū)動(dòng)電路和接收驅(qū)動(dòng)電路的設(shè)計(jì)方案，并對(duì)它們的功能進(jìn)行了詳細(xì)地說明。最后搭建實(shí)驗(yàn)平臺(tái)，并對(duì)電路的輸入、輸出模塊進(jìn)行了測(cè)試。實(shí)驗(yàn)結(jié)果表明，換能器電路運(yùn)行良好，可以為超聲波高精度測(cè)量領(lǐng)域的應(yīng)用提供參考。As a practical means of detection, ultrasonic transducer can realize the conversion between theinformation carried by SOUND wave and electric energy.It has the advantages of excellent performance,low cost, convenient operation and debugging, so plays an important role in industrial and agriculturalproduction.However, the transmitting frequency of the driving circuit for most transducer is 40 kHz.Thecircuit of 1 MHz ultrasonic transducer is designed In this paper. It mainly introduces the emissive drivingcircuit and the receiving circuit design and the detailed function of them. Finally, the experimentalplatform is built, and the circuit of input and output were tested. Experiments show that the transducer＇ s...
