Data acquisition equipment for physics can be quite expensive. As an alternative, data can be acquired using a low-cost Arduino microcontroller. The Arduino has been used in physics labs where the data are acquired using the Arduino software. The Arduino software, however, does not contain a suite of tools for data fitting and analysis. The data are typically gathered first and then imported manually into an analysis program. There is a way, however, that allows data gathered by the Arduino to be imported in real time into a data analysis package. Illustrated in this article are add-ins for Excel, MATLAB, and LabVIEW that import data directly from the Arduino and allow for real-time plotting and analysis.
