Teaching Physics by Arduino during COVID-19 Pandemic: Oscillation of a simple pendulum

Abstract

The COVID-19 impacted the teaching; indeed, both schools and universities had to shift from face-to-face to distance teaching organizing on-line lectures. Thanks to easily accessible materials, smartphones physics apps, on-line toolsand devices, it's possible to perform laboratory practice even in this period. In this paper, a method to measure the gravitational acceleration by oscillation of a simple pendulum, using Arduino board, is presented.
