Voltmeter with Esp32
Author: Olteanu Eduard-Florin
Introduction
The main focus of this project is to be able to accurately measure low-voltage batteries in order to determine whether or not they are still functional.
Additionally, the user can save the values in a database in order to be easier to remember or review the values at a later time and not measure them again.
