explaining the program

with the arduino program loaded, let's use this one to perform bidirectional communication,
make sure to close the arduino ide program or any program that is using the serial comic method with the arduino


(Importing Libraries):
serial: Library for serial communication between the computer and the Arduino device.
serial.tools.list_ports: Provides functions to list the serial ports available on the computer.
threading: Library to support concurrent programming using threads.
time: Library for handling time.

(SharedState Class):
A class that represents a state shared between threads. It has a lock to guarantee
safe synchronization between threads and a state variable that can be shared.

(Function send_serial_data):
Sends encoded data to the specified serial port.

(Function read_data_serial):
Reads and decodes a line of data from the serial port.

(Function receive_data_from_arduino):
Runs on a thread to continuously receive data from the Arduino. If data is available, it is printed to the screen.

(Function find_device_port):
Searches for and finds a serial port associated with the device that operates at the specified baud rate.

(main_loop function):
The main function that creates a serial connection to the device, starts a thread to receive data from the Arduino, and then
starts a loop to send and receive data between the computer and the Arduino.

(main function):
The function that sets the operating frequency of the microcontroller and starts the execution of the main program.

(Main Execution):
Checks if the script is running as the main program and calls the main() function to start the Arduino communication program.
