In this Tutorial, We will build an Arduino based Multi channel data acquisition system that will log sensor data to a SQLite 3 database using Python.

Compared to MySQL or Maria DBMS ,SQLite is a server less, self-contained database engine that operates as a library within the application. This makes it suitable for embedded systems like raspberry pi and scenarios where a separate database server is not practical. It is ideal for single user and cross platform use.

Logging Arduino serial port data to an SQLite3 database using Python involves reading data from the Arduino via serial communication and storing it in an SQLite3 database using Python. Below is an outline of the process:

Hardware Components
Arduino Board: This is the hardware device that collects data and sends it over the serial port to the computer.
Software Components
Arduino Sketch: Write an Arduino sketch to collect data from sensors or other sources and send it over the serial port to the computer.

Python Script: Write a Python script to read data from the serial port, parse it, and store it in an SQLite3 database.

Steps to Implement
Install Required Libraries: Ensure you have the pyserial library installed in your Python environment. You can install it using pip: pip install pyserial.

Write Arduino Sketch: Write an Arduino sketch to read data from sensors or other sources and send it over the serial port to the computer. Here's a simple example:
