| import RPi.GPIO as GPIO | Import the RPi.GPIO module into the python sketch |
| GPIO.setmode(GPIO.BCM) | Use Broadcom pin numbers (GPIO 14, GPIO 15 etc) |
| GPIO.setmode(GPIO.BOARD) | Use board pin numbers (4,5, 8 etc) |
| GPIO.getmode() | Returns current pin numbering mode (BCM, BOARD, or None) |
| GPIO.setup([pin number], GPIO.IN) | Set up the pin at [pin number] to be an input |
| GPIO.setup([pin number], GPIO.IN, pull_up_down=GPIO.PUD_DOWN) | Set up the pin at [pin number] to be an input with internal pull down resistance |
