This digital student book offers comprehensive coverage of the Cambridge Advanced National in Engineering Unit F134: Programmable electronics. Mapped to the OCR specification , this book has been designed to help students and teachers build the confidence, knowledge and skills needed to succeed in the new qualification. Ideal as both a learning and reference tool, it is structured to follow the order of the specification and unpack its content in an easy-to-follow, digestible way. It will help students learn key concepts and information, while providing teachers with guidance on the breadth and depth of content they're required to teach. Written by David Hills-Taylor, an experienced teacher and practitioner, this book will help students to understand how microcontroller systems and their components are designed, developed assembled and programmed. It will explore how microcontrollers have now largely replaced traditional electronic integrated circuits, leading to ever smaller and more powerful electronic devices, and how, as a result, there is huge demand for engineers with the knowledge and skills to design, develop and program these types of systems. This book is written to be engaging and motivating. “Learning in Context” examples help students relate the concepts they are learning to the real world, and worked examples guide their development of essential skills, step-by-step. Furthermore, frequent quick-check questions help them to assess their progress and understanding of each topic. We are working towards endorsement by OCR.
