This module introduces students to both analogue and digital electronics as found in all electronics systems. The module approaches the subject both theoretically and practically, including topics such as analysis of circuits, CPU architectures and interfacing to micro-controllers. By the end of the module, students will be able to design and implement both circuits and python based embedded programs in electronics hardware that contains four main elements: 1) sensors that produce electrical signals from physical world; 2) driver and actuators that provide mechanical movements; 3) communication links that passes messages between a mobile device and the embedded electronic systems; 4) embedded programming that gives the electronic system intelligence and adaptability.               

Learning Outcomes

On completion of this module, students will be better able to:

•   Analyse basic circuits to predict voltages and currents
•   Understand digital logic and basic CPUs
•   Build simple passive circuits to meet specifications
•   Measure electrical signals, appreciating issues of accuracy
•   Produce working robots that can sense, drive, link, and measure by combining electronic themes
