1. from machine import Pin
   
2. p0 = Pin(0, Pin.OUT)    # create output pin on GPIO0
   
3. p0.high()               # set pin to high
   
4. p0.low()                # set pin to low
   
5. p0.value(1)             # set pin to high
   
6. p2 = Pin(2, Pin.IN)     # create input pin on GPIO2
   
7. print(p2.value())       # get value, 0 or 1
   
8. p4 = Pin(4, Pin.IN, Pin.PULL_UP) # enable internal pull-up resistor
   
9. p5 = Pin(5, Pin.OUT, value=1) # set pin high on creation
