I can't read analog pin with python, pyfirmata

Question

I'm trying to read analog pin for push button. But ı cant read. ı get this error all the time.

My code:

import pyfirmata
import time
from pyfirmata import util


port = "COM4" # port number
board = pyfirmata.Arduino(port)

it = util.Iterator(board)
it.start()

pin_redLed = 8 # red LED pin number

board.analog[11].enable_reporting()



while True : 
            print (board.analog[11].read())
            time.sleep(1)

Error Message: enter image description here

You tag `arduino-uno`, you run python on Arudino Uno which has 2kB ram? — hcheung, Dec 08 '22 at 03:14

I solved it:

import pyfirmata
import time
from pyfirmata import util


port = "COM4" # port number
board = pyfirmata.Arduino(port)

it = pyfirmata.util.Iterator(board)
it.start()

pin_redLed = 8 # red LED pin number
pin_button = 10 # button pin number

board.digital[pin_button].mode = pyfirmata.INPUT

while True : 
        sw = board.digital[pin_button].read()
        if sw is True :
                board.digital[pin_redLed].write(1)
        else :
                board.digital[pin_redLed].write(0)
        time.sleep(0.1)
