# from machine import Pin
# p0 = Pin(0, Pin.OUT)    # create output pin on GPIO0

# p0.low()                # set pin to low
# p0.value(1)             # set pin to high

# p2 = Pin(2, Pin.IN)     # create input pin on GPIO2

# p4 = Pin(4, Pin.IN, Pin.PULL_UP) # enable internal pull-up resistor
# p5 = Pin(5, Pin.OUT, value=1) # set pin high on creation
# Available pins are: 0, 1, 2, 3, 4, 5, 12, 13, 14, 15, 16,
# which correspond to the actual GPIO pin numbers of ESP8266 chip
# Note that Pin(1) and Pin(3) are REPL UART TX and RX respectively.
# Also note that Pin(16) is a # special pin (used for wakeup from deepsleep mode)
# and may be not available for use with higher-level classes like
