20181009 让树莓派小车动起来

普通小车：

from gpiozero import Robot
from time import sleep
from gpiozero.pins.pigpio import PiGPIOFactory
factory = PiGPIOFactory(host='raspberry00.local')


robot = Robot(left=(15, 14), right=(18, 23),pin_factory=factory)

for i in range(4):
    robot.forward()
    sleep(2)
    robot.right()
    sleep(0.5)
    
robot.stop()

from gpiozero import Robot

from time import sleep

from gpiozero.pins.pigpio import PiGPIOFactory

factory = PiGPIOFactory(host='raspberry00.local')

robot = Robot(left=(15, 14), right=(18, 23),pin_factory=factory)

for i in range(4):

robot.forward()

sleep(2)

robot.right()

sleep(0.5)

robot.stop()

键控小车：

from gpiozero import Robot
from time import sleep
from gpiozero.pins.pigpio import PiGPIOFactory
from gpiozero import Button

factory = PiGPIOFactory(host='raspberry00.local')
robot = Robot(left=(15, 14), right=(18, 23),pin_factory=factory)

button = Button(21,pin_factory=factory)

button.wait_for_press()# wait for button pressed
print("Button was pressed")

for i in range(4):
    robot.forward()
    sleep(2)
    robot.right()
    sleep(0.5)
    
robot.stop()
