Microcontroller-based Titration for Remote Lab

Laboratory courses are an essential part of the higher education of natural scientists and engineers. Efforts to make university teaching more sustainable and digital are leading to changes in this area. Digital laboratories or laboratories with digital elements can enable more flexible learning, but also require a higher degree of self-organization on the part of the students. This paper shows the development of a digital setup for titrations, a common laboratory method of quantitative chemical analysis. The pedagogical concept regarding learning outcomes, learning method and examination is presented and the first steps of the technical realization of the setup are shown. In addition, initial feedback is presented from students regarding the application of such a titration setup and how they feel about using it.
