The Raspberry Pi's GPIO (General Purpose Input/Output) pins allow users to interface with external hardware like LEDs, sensors, and motors. Python provides several libraries to control these GPIO pins effectively. Below are some of the most commonly used libraries:
RPi.GPIO Library
The RPi.GPIO library is a widely-used Python module for controlling GPIO pins on Raspberry Pi. It is beginner-friendly and provides a simple interface for configuring pins as inputs or outputs, reading their states, and controlling them.
Key Features:
Supports basic GPIO operations like input, output, and software PWM.
Allows pin numbering by physical board layout (GPIO.BOARD) or Broadcom chip numbering (GPIO.BCM).
Includes event detection for edge-triggered interrupts.
Installation:
sudo apt-get updatesudo apt-get install python3-rpi.gpioCopied!✕CopyOr install via pip:
sudo pip3 install RPi.GPIOCopied!✕CopyExample Code:
