Abstract
The LIGO analogy lab [Am. J. Phys. 87, 44 (2019)] includes a complicated pair of circuits to sense and control the length of an optical cavity. This Note describes an alternate, Arduino-based controller that is significantly less complex and easier to troubleshoot.
期刊介绍:
The mission of the American Journal of Physics (AJP) is to publish articles on the educational and cultural aspects of physics that are useful, interesting, and accessible to a diverse audience of physics students, educators, and researchers. Our audience generally reads outside their specialties to broaden their understanding of physics and to expand and enhance their pedagogical toolkits at the undergraduate and graduate levels.
