Based on problem-based learning, this UP aims to introduce students to the management of the connection between a connected object (microcontroller and its embedded software) on the one hand, and the physical world on the other.
After a quick introduction to the electronic course support system, students will learn to manage and optimize the measurement chain corresponding to different types of sensors, analog or digital. They will implement digital processing of sensor signals and finally a control loop.
Pedagogy: Students will have to solve various concrete problems in a few hours, quick reframing courses to determine the theoretical aspects. This work will be carried out using Cypress PSoC 5LP modules and the "Creator" programming environment, allowing to work with great ease (few wiring) both on C programming and on analog or digital components.
The UP concludes with a small temperature control project.
