可是我把判断删掉以后舵机还是不动

我想利用payload识别为1时对舵机进行控制，但是运行的时候检测到二维码信息为1舵机不会动!

import sensor, image
import time
from pyb import Servo

s2 = Servo(2) # P8
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QQVGA) # can be QVGA on M7...
sensor.skip_frames(30)
sensor.set_auto_gain(False) # must turn this off to prevent image washout...
while(True):
    img = sensor.snapshot()
    img.lens_corr(1.8) # strength of 1.8 is good for the 2.8mm lens.
    for code in img.find_qrcodes():
        print(code.payload())
        if code.payload() == 1:
           for i in range(-90,90):
               s2.angle(i)
