我是连接了2号io口，需要修改成你的io口
import time
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BCM)
GPIO.setup(2, GPIO.OUT)
p = GPIO.PWM(2, 150)
p.start(0)
try:
while 1:
for dc in range(0, 101, 5):
p.ChangeDutyCycle(dc)
time.sleep(0.1)
for dc in range(100, -1, -5):
p.ChangeDutyCycle(dc)
time.sleep(0.1)
except KeyboardInterrupt:
pass
p.stop()
GPIO.cleanup()
