Electronics has become pervasive in our lives as a powerful technology with applications in a wide range of fields including healthcare, home automation, environmental monitoring, robotics, or entertainment. This course teaches how to build electronic circuits that interact with the physical world through sensors and actuators and communicate wirelessly with the internet to cooperate with other devices and with humans. In the laboratory participants design and build representative samples such as an autonomous solar weather station and robots that exchange information with and are controlled from the cloud.
