from digitalio import DigitalInOut, Pull
button = DigitalInOut(board.D3) # defaults to input
button.pull = Pull.UP # turn on internal pull-up resistor

 Read a Potentiometer

import board
import analogio
potknob = analogio.AnalogIn(board.A1)
position = potknob.value  # ranges from 0-65535
pos = potknob.value // 256  # make 0-255 range
