Code

This code move to neutral position (2.5) to 90º (6.25) if you want to move 180º then is (12.5).

import RPi.GPIO as GPIO
import time

GPIO_PIN = 8

GPIO.setmode(GPIO.BOARD)
GPIO.setup(GPIO_PIN, GPIO.OUT)

p = GPIO.PWM(GPIO_PIN, 50)
p.start(2.5)

p.ChangeDutyCycle(2.5)
time.sleep(1)
p.ChangeDutyCycle(7.25)
time.sleep(1)
p.ChangeDutyCycle(2.5)
time.sleep(1)

p.stop()
GPIO.cleanup()
