如何使用Python控制两个伺服电机，给出事例代码

您好，以下是使用Python控制两个伺服电机的示例代码：

import RPi.GPIO as GPIO
import time

# 设置GPIO模式为BCM
GPIO.setmode(GPIO.BCM)

# 设置引脚号
servo1_pin = 18
servo2_pin = 19

# 设置PWM引脚
GPIO.setup(servo1_pin, GPIO.OUT)
GPIO.setup(servo2_pin, GPIO.OUT)

# 设置PWM频率
pwm1 = GPIO.PWM(servo1_pin, 50)
pwm2 = GPIO.PWM(servo2_pin, 50)

# 启动PWM
pwm1.start()
pwm2.start()

# 控制伺服电机
def set_servo_angle(pwm, angle):
    duty_cycle = 2.5 + 10 * angle / 180
    pwm.ChangeDutyCycle(duty_cycle)
    time.sleep(.3)

# 控制两个伺服电机
try:
    while True:
        set_servo_angle(pwm1, )
        set_servo_angle(pwm2, 90)
        set_servo_angle(pwm1, 90)
        set_servo_angle(pwm2, )
except KeyboardInterrupt:
    pwm1.stop()
    pwm2.stop()
    GPIO.cleanup()

希望对您有所帮助。
