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
