Summary:

Designed for both the student and hobbyist, this updated revision is an introduction to the theory and practice of electronics including advances in microcontrollers, sensors, and wireless communication. Each chapter contains a brief lab to demonstrate the topic under discussion, then moves on to use all of the knowledge mastered to build a programmable robot. New material on using Raspberry Pi and Python has been included. The companion files include short videos of the labs, soldering skills, and code samples for programming the robot. Covering both the theory and also its practical applications, this text leads the reader through the basicscientific concepts underlying electronics, building basic circuits, learning the roles of the components, the application of digital theory, and the possibilities for innovation by combining sensors, motors, and microcontrollers. It includes appendices on mathematics for electronics, a timeline of electronics innovation, careers in electronics, and a glossary.FEATURES:Includes companion files with over twenty video tutorials on currents, soldering, power supply, resistors, decoder circuits, Raspberry Pi, animations of featured circuits and more (files available from the publisher for downloading)Features chapters on using Raspberry Pi and Python in electronic projects and a chapter on Cybersecurity and the Internet of Things (IoT) for Electronic ProjectsLeads the reader through an introductory understanding of electronics with simple labs and then progresses to the construction of a microcontroller-driven robot using opensource software and hardware
