In this course, students would develop competency in ways of designing and making simple mechanical and digital devices. This would involve using ideas such as feedback loops and conditional responses. While we would like students to appreciate the skill and sophistication of a purely mechanical system such as the ​‘governor’ in James Watt’s steam engine, this course will equip them to build quick prototypes with sensors, microcontrollers, circuits and programming code. Students would learn about data-logging and putting up live information on a web page. This would find application in diverse situations ranging from citizen science to agriculture.
