Sista Love was a chart-topping girl group that had it all—fame, fortune and failure. After three years apart, Harmony, Melody, and Lyric are forced back together after the death of their mother. Their forced reunion rekindled past hurt, lies, and deceit, but it is new lies, backstabbing, and jealousy that will bring the sisters to the brink of destruction. Harmony is piecing her life back together after her husband’s relapse back into addiction and his affair with her sister Melody. Now Harmony must decide if she will walk away or stand and fight. When she meets a handsome stranger, her decision will become that much harder. Will she become a two-timer, or will she give up on her marriage for good? Melody continues to throwing her money around to get what she wants. Still devastated by her ex-boyfriend’s blatant two-timing, Melody turns to her sister’s husband for comfort, but quickly realizes that he is only around because she is his constant supply of drugs and the fast life. With pressures mounting from all sides, Melody will have to figure out who she can trust. Will she risk it all to find love, or will her past come back to snatch her from her pedestal? Lyric is haunted by a secret she’s kept from Harmony and finds out the hard way that turning back to drugs to run from her problems has landed her in the worst predicament of her life. Will Lyric let her addiction, once again, take her to the brink of death, or will she embrace sobriety once and for all?

Defying time, Jack Breton crosses into a parallel world to regain Kate - the wife who, nine years earlier, was found raped and strangled in a lonely park. But, in the alternate time-stream Kate is married to his double, John. And for one husband to remain either Jack or John must die.

This book is about the Arduino microcontroller and the Arduino concept. The visionary Arduino team of Massimo Banzi, David Cuartielles, Tom Igoe, Gianluca Martino, and David Mellis launched a new innovation in microcontroller hardware in 2005, the concept of open-source hardware. Their approach was to openly share details of microcontroller-based hardware design platforms to stimulate the sharing of ideas and promote innovation. This concept has been popular in the software world for many years. In June 2019, Joel Claypool and I met to plan the fourth edition of Arduino Microcontroller Processing for Everyone! Our goal has been to provide an accessible book on the rapidly evolving world of Arduino for a wide variety of audiences including students of the fine arts, middle and senior high school students, engineering design students, and practicing scientists and engineers. To make the book even more accessible to better serve our readers, we decided to change our approach and provide a series of smaller volumes. Each volume is written to a specific audience. This book, Arduino II: Systems, is a detailed treatment of the ATmega328 processor and an introduction to C programming and microcontroller-based systems design. Arduino I: Getting Started provides an introduction to the Arduino concept. Arduino III: the Internet of Things explores Arduino applications in the Internet of Things (IoT).

Embedded systems are today, widely deployed in just about every piece of machinery from toasters to spacecraft. Embedded system designers face many challenges. They are asked to produce increasingly complex systems using the latest technologies, but these technologies are changing faster than ever. They are asked to produce better quality designs with a shorter time-to-market. They are asked to implement increasingly complex functionality but more importantly to satisfy numerous other constraints. To achieve the current goals of design, the designer must be aware with such design constraints and more importantly, the factors that have a direct effect on them.One of the challenges facing embedded system designers is the selection of the optimum processor for the application in hand; single-purpose, general-purpose or application specific. Microcontrollers are one member of the family of the application specific processors.The book concentrates on the use of microcontroller as the embedded system?s processor, and how to use it in many embedded system applications. The book covers both the hardware and software aspects needed to design using microcontroller.The book is ideal for undergraduate students and also the engineers that are working in the field of digital system design.Contents• Preface;• Process design metrics;• A systems approach to digital system design;• Introduction to microcontrollers and microprocessors;• Instructions and Instruction sets;• Machine language and assembly language;• System memory; Timers, counters and watchdog timer;• Interfacing to local devices / peripherals;• Analogue data and the analogue I/O subsystem;• Multiprocessor communications;• Serial Communications and Network-based interfaces.

This second edition of The x86 Microprocessors has been revised to present the hardware and software aspects of the subject in a logical and concise manner. Designed for an undergraduate course on the 16-bit microprocessor and Pentium processor, the book provides a detailed analysis of the x86 family architecture while laying equal emphasis on its programming and interfacing attributes. The book also covers 8051 Microcontroller and its applications completely.
