In today's world, digital technologies influence our life as never before, the surrounding electronics has an increasingly bigger impact on the different aspects of our life. The understanding of this new reality goes through a paradigm change where electronic devices are no longer black boxes that hide their operation, but tools that allow us to understand and change our environment according to our needs. Likewise, the flow and the amount of data describing our environment and ourselves increases in an accelerated way. The data generated, either by sensors or by interactions between the actors of these systems (including humans) is accumulated and enables autonomous decision-making. The ability to understand and manage tools for the management, processing and collection of data is a central part in the development of new systems. The limit between hardware and software is increasingly blurred, the ability to prototype simultaneously in both areas allows us to design systems that best adapt to our needs. The use of open prototyping tools such as Arduino and Raspberry Pi facilitates this development to profiles with a more general vision of current needs and problems. The objective of this class is that the student is able to prototype systems focused on the resolution of a real problem using hardware and software resources. At the end of the course the student must present an interactive project that includes at least:  Use of sensor(s) as inputs.  Data management and processing.  Remote control through a user interface (mobile application, web interface)  Use of actuator(s) as outputs The proposed concept must be developed in response to a real problem and the presented devices must be a student own design, capable of demonstrating its functionalities through circuits and code developed by the students.
