在死循环里判断一下时间。

import sensor, image, time
import pyb
sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)

clock = time.clock()

flag = True
while(True):
    if flag:
        sec = pyb.millis()//1000 % 6
        if sec == 0:
            print("响")
        else:
            print("不响")
    clock.tick()
    img = sensor.snapshot()
