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.
The libraries used are:
#include <Adafruit_ADS1X15.h> #include <WiFi.h> #include <LiquidCrystal_I2C.h> #include <Arduino.h> #include <Firebase_ESP_Client.h>
Communication between the ESP 32 and both the ADS1115 and the LCD screen is done through the I2C protocol
The main usecase of this project is to measure the voltage of batteries.
We can see that the value is pretty accurate, only 0.01 error delta.
Also, if the button is pressed the value is stored in the database.
