    Reading GPIO pins in Python is a common task when working with Raspberry Pi to interact with external hardware like sensors or buttons. Below are two popular methods to achieve this.

    Using the gpiozero Library

    The gpiozero library is beginner-friendly and simplifies GPIO interactions.

    Steps:

    • Install gpiozero (if not already installed):

    python3 -m pip install gpiozero
    Copied!

    • Write the Code:

    from gpiozero import Button

    button = Button(4) # Replace 4 with your GPIO pin number

    while True:
    if button.is_pressed:
    print("Button is pressed")
    else:
    print("Button is not pressed")
    Copied!

    • Run the Script: Save the file (e.g., read_gpio.py) and execute it:

    python3 read_gpio.py
    Copied!

    Using the RPi.GPIO Library

    The RPi.GPIO library provides more control but requires manual setup and cleanup.

    Steps:

    • Install RPi.GPIO:

    sudo apt-get install python3-rpi.gpio
    Copied!

    • Write the Code:
