atexit: a must have python code for Arduino interactions

[fukurou]

import serial
import time
import atexit

class SerialReader:
    def __init__(self, port='COM3', baud_rate=9600, timeout=1):
        self.ser = serial.Serial(port, baud_rate, timeout=timeout)
        atexit.register(self.close)  # Register the close method to be called on exit

    def read_serial_data(self, num_readings=10):
        readings = []
        for _ in range(num_readings):
            if self.ser.in_waiting > 0:
                line = self.ser.readline().decode('utf-8').rstrip()
                readings.append(line)
                print(line)
            time.sleep(1)  # Delay between readings
        return readings

    def close(self):
        self.ser.close()

# Example usage
if __name__ == '__main__':
    reader = SerialReader()
    data = reader.read_serial_data()

that's the laptop side code.
the nice thing about atexit is, will handle all the wrap up, needed to be done when the program closes.
and as you can see you set it whenever(the c'tor in this case), instead of the end of the program.
