Experiment: Determination of the time constant of an RC circuit - Arduino and Python

Principles and objectives:

Study the charging and discharging of a capacitor in an RC circuit, using an Arduino board, and Python language programs.

The provided Python distribution by Jeulin includes a library of functions to create a program that measures the voltage across the capacitor.

The functions offered notably allow for displaying the charging and discharging curves, and determining the time constant of the circuit created, in Python language.
