# You can use any available GPIO pin on both a microcontroller and a Raspberry Pi.
# The following pins are simply a suggestion. If you use different pins, update
# the following code to use your chosen pins.

# To use with CircuitPython and a microcontroller:
coils = (
    digitalio.DigitalInOut(board.D9),  # A1
    digitalio.DigitalInOut(board.D10),  # A2
    digitalio.DigitalInOut(board.D11),  # B1
    digitalio.DigitalInOut(board.D12),  # B2
)

# To use with a Raspberry Pi:
# coils = (
#     digitalio.DigitalInOut(board.D19),  # A1
#     digitalio.DigitalInOut(board.D26),  # A2
#     digitalio.DigitalInOut(board.D20),  # B1
#     digitalio.DigitalInOut(board.D21),  # B2
