Incorporating the raspberry pi into laboratory experiments in an introductory MATLAB course

Abstract

Many introductory computer-programming classes in engineering fields stress coding skills, but they often do not incorporate data acquisition or output until later classes. Interfacing computers with laboratory equipment is an excellent way to engage and excite students who may not otherwise see the importance of programming. Additionally, they collect and process data directly instead of receiving artificially or simulated data. Our laboratory curriculum integrates the Raspberry Pi, an inexpensive and versatile single-board computer, with a standard computer to provide dynamic and engaging biomedical-engineering-related programming activities in an introductory MATLAB course, all without complicated MATLAB commands or routines. The total cost for each station is only about 75 or less. Concurrently, more complicated engineering concepts are introduced at this early level to pique interest in biomedical engineering and improve learning in later classes when these concepts are described in more detail. Students report enjoying programming more and seeing its quintessential role in engineering experiments while being better prepared for later computer-based courses and job opportunities.
