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 (Arduino and Netduino). 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 of the robot. Covering both the theory and also its practical applications, this text leads the reader through the basic scientific 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 moreFeatures a chapter on using Raspberry Pi and Python in electronic projects and a new chapter on Cybersecurity and the Internet of Things (IoT)Leads the reader through an introductory understanding of electronics with simple labs and then progressing to the construction of a microcontroller-driven robot using open source software and hardware (Netduino and Arduino versions)Presents theoretical concepts in a conversational tone, followed by hands-on labs to engage readers by presenting practical applications.The companion files are also available online by emailing the publisher with proof of purchase at info@merclearning.com.
