I wrote this book so that students, hobbyists, and engineers alike can take advantage of the Arduino PLATFORM by creating several projects that will teach them about the engineering process. I also wanted to guide the reader through introductory projects so that they could get a firm grasp on the Arduino Language, and how to incorporate several pieces of hardware to make their own projects. This book offers so much information on the Arduino, not just the basic LED projects but it offers different peripherals such as Ultrasonic sensor, the Xbox? controller, Bluetooth, and much more. This book also teaches the non-engineer to follow a process that will help them in future project (not just Arduino projects).

Since its release, Arduino has become more than just a development PLATFORM; it has become a culture built around the idea of open source and open hardware, and one that is reimagining computer science and education. Arduino has opened hardware development by making the starting skills easy to obtain, but retaining the complexities of real-world application. This combination makes Arduino a perfect environment for school students, seasoned developers, and designers. This is the first Arduino book to hold the title of “Pro,” and demonstrates skills and concepts that are used by developers in a more advanced setting. Going beyond projects, this book provides examples that demonstrate concepts that can be easily integrated into many different projects and provide inspiration for future ones. The focus of this book is as a transition from the intermediate to the professional.

在傳統(tǒng)智能小車驅(qū)動電路設(shè)計中,較多考慮使用直流電機(jī)還是步進(jìn)電機(jī),電機(jī)功率、能耗等性能參數(shù)。使用具有armCortexM4內(nèi)核的STM32嵌入式平臺控制四輪的4個直流電機(jī)。文章基于PWM技術(shù)及PID算法,對四輪進(jìn)行精準(zhǔn)地速度、轉(zhuǎn)向及啟停控制,實(shí)驗(yàn)表明此小車具有優(yōu)越各種地形適應(yīng)能力。In the traditional intelligent car drive circuit design,DC motor or stepping motor,motor power,energy consumption and other performance parameters are considered.The four DC motors with four wheels are controlled by STM32 embedded PLATFORM with arm Cortex M4 kernel.Based on the PWM technology and PID algorithm,the accurate ground speed,steering,and start-stop control of the four wheels are carried out.The experiment shows that the vehicle has the superior adaptability to all kinds of terrains.

基于DSP28035的高速永磁無刷直流電機(jī)驅(qū)動系統(tǒng)，包括論文和軟硬設(shè)計資料。摘要參賽作品為基于DSP28035的高速永磁無刷直流電機(jī)驅(qū)動系統(tǒng)。該系統(tǒng)以一臺額定轉(zhuǎn)速60 krpm的高速永磁無刷直流電機(jī)、交錯并聯(lián)的Buck電路以及全橋電路為硬件平臺，以DSP28035為控制核心，實(shí)現(xiàn)了調(diào)壓調(diào)速功能和基于坐標(biāo)變換的無位置傳感器新技術(shù)。為實(shí)現(xiàn)該系統(tǒng)要求，本作品充分利用了DSP28035的資源例如：CLA模塊，模擬比較器、HPWM模塊以及AD轉(zhuǎn)換模塊等。AbstractThis work is the drive system for a high speed permanent magnet burshless dc motor based on DSP28035. The hardware PLATFORM consists of a BLDC motor(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the motor’s speed with voltage and the function of sensorless control based on the coordinate transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁無刷直流電機(jī)驅(qū)動系統(tǒng)由于基波頻率較高（一般在1kHZ以上），利用逆變橋斬波進(jìn)行調(diào)速的控制方式通常會受到開關(guān)管開關(guān)頻率的限制，因此該系統(tǒng)多采用三相全橋前級加Buck電路進(jìn)承擔(dān)調(diào)壓調(diào)速的功能，而三相全橋主要承擔(dān)邏輯換相的功能。然而，傳統(tǒng)Buck電路所需電感的體積較大，增加了系統(tǒng)的體積，降低了系統(tǒng)的功率密度。
