motor和servo

程序简单易读，不再做注释

motor.py

from gpiozero import Motor
from gpiozero import LED
led = LED(2)
motor = Motor(20, 21)
while True:
    led.on()
    motor.forward()

servo.py

from gpiozero import Servo
from time import sleep
 
servo = Servo(17)
while True:
    servo.min()
    sleep(1)
    servo.mid()
    sleep(1)
    servo.max()
    sleep(1)
