Raspberry Pi Pico - Thonny 解释器的问题

Question

I have a trouble with programming Raspberry Pi Pico. I am using Thonny IDE and micropython. I am just a beginner so just download code from their website ( https://projects.raspberrypi.org/en/projects/getting-started-with-the-pico/6 ) and install it to microcontroller. But when I save this code:

from machine import Pin
import time
led = Pin(15, Pin.OUT)
button = Pin(14, Pin.IN, Pin.PULL_DOWN)
while True:
if button.value():
    led.toggle()
    time.sleep(0.5)

I receive this message:

Traceback (most recent call last): File "", line 10 IndentationError: unindent doesn't match any outer indent level Could you help me please?

Answer 1

You need to indent your code properly:

from machine import Pin
import time
led = Pin(15, Pin.OUT)
button = Pin(14, Pin.IN, Pin.PULL_DOWN)
while True:
    if button.value():
        led.toggle()
        time.sleep(0.5)

Answer 2

Maybe try this:

from machine import Pin
import time
led = Pin(15, Pin.OUT)
button = Pin(14, Pin.IN, Pin.PULL_DOWN)
while True:
    if button.value():
        led.toggle()
        time.sleep(0.5)

I just changed if button.value(): four more spaces in so its inside the while true: loop.
