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).

The main aim of this book is to present a unified, systematic description of basic and advanced problems, methods and algorithms of the modern con- trol theory considered as a foundation for the design of computer control and management systems. The scope of the book differs considerably from the topics of classical traditional control theory mainly oriented to the needs of automatic control of technical devices and technological proc- esses. Taking into account a variety of new applications, the book presents a compact and uniform description containing traditional analysis and op- timization problems for control systems as well as control problems with non-probabilistic models of uncertainty, problems of learning, intelligent, knowledge-based and operation systems – important for applications in the control of manufacturing processes, in the project management and in the control of computer systems.

The PW5300 is a current mode boost DC-DC converter. Its PWM circuitry with built-in 0.2? powerMOSFET make this regulator highly power efficient. The internal compensation network alsominimizes as much as 6 external component counts. The non-inverting input of error amplifierconnects to a 0.6V precision reference voltage and internal soft-start function can reduce the inrushcurrent. The PW5300 is available in the SOT23-6L package and provides space-saving PCB for theapplication fields

解讀 5G 八大關(guān)鍵技術(shù) 【摘要】5G 不是一次革命，5G 是 4G 的延續(xù)，我相信 5G 在核心網(wǎng)部分不會有太 大的變動，5G 的關(guān)鍵技術(shù)集中在無線部分。 在進入主題之前，我覺得首先應(yīng)該弄清楚一個問題：為什么需要 5G？不是因 為通信工程師們突然想改變世界，而炮制了一個 5G。是因為先有了需求，才有了 5G。什么需求？ 未來的網(wǎng)絡(luò)將會面對：1000 倍的數(shù)據(jù)容量增長，10 到 100 倍的無線設(shè)備連接， 10 到 100 倍的用戶速率需求，10 倍長的電池續(xù)航時間需求等等。坦白的講，4G 網(wǎng)絡(luò)無法滿足這些需求，所以 5G 就必須登場。 但是，5G 不是一次革命。5G 是 4G 的延續(xù)，我相信 5G 在核心網(wǎng)部分不會有 太大的變動，5G 的關(guān)鍵技術(shù)集中在無線部分。雖然 5G 最終將采用何種技術(shù)，目前 還沒有定論。不過，綜合各大高端論壇討論的焦點，我今天收集了 8 大關(guān)鍵技術(shù)。 當(dāng)然，應(yīng)該遠不止這些。 1.非正交多址接入技術(shù) （Non-Orthogonal Multiple Access,NOMA） 我們知道 3G 采用直接序列碼分多址（Direct Sequence CDMA ，DS-CDMA） 技術(shù)，手機接收端使用 Rake 接收器，由于其非正交特性，就得使用快速功率控制 （Fast transmission power control ，TPC)來解決手機和小區(qū)之間的遠-近問題。 而 4G 網(wǎng)絡(luò)則采用正交頻分多址（
