I make a project in Cisco PT. I connected the door to SBC. I want the LCD to display “Open” when the door is open, and the LCD to display “Closed” when the door is closed.

but I don’t know why door status is always 0 if I open or I close the door.

I tried this:

#pin d1 door
#pin d0 LCD

if digitalRead(1) == HIGH: #1 is door pin
    customWrite(0, "OPEN")
else:
    customWrite(0, "Close")

Full code

from gpio import * 

pinMode(5, INPUT) #this is a switch and if it is turned on then it is supposed to check the door 
pinMode(0, OUTPUT) 
pinMode(1, INPUT) 

while True: 
    if digitalRead(5) == HIGH: 
        if digitalRead(1) == HIGH: 
            customWrite(0, "Open") 
        else: 
            customWrite(0, "Closed")
