该怎么控制它转动的角度呢？怎么让它随停呢？

@kidswong999 如果要自己写一个舵机控制函数的话，要怎么写啊？

# main.py -- put your code here!

sensor.reset()                         # Reset and initialize the sensor.

sensor.set_windowing((240, 240))       # Set 240x240 window.

    if maxxx == 3:
        s1.angle(90)
        time.sleep_ms(1000)
        s1.angle(0)
        time.sleep_ms(1000)
        s2.angle(90)
        time.sleep_ms(1000)
        s2.angle(0)
        time.sleep_ms(3000)
        s1.angle(180)
        time.sleep_ms(1000)
        s1.angle(0)

@kidswong999 不行，运行你这个也只能是舵机转90度之后再回到0度。

from pyb import Servo
import time
s1 = Servo(1)
s2 = Servo(2)
s1.angle(180)
time.sleep_ms(1000)

import pyb
s1 = pyb.Servo(1)   # create a servo object on position P7 #在P7引脚创建servo对象
s1.angle(45)        # move servo 1 to 45 degrees #将servo1移动到45度
