当红外传感器检测到某些东西时，我的伺服电机不动

Question

我试图让伺服电机旋转180度，然后当红外传感器感应到什么东西时，再返回到0度 Circuit

import time
from pyfirmata import Arduino, util

board = Arduino('COM5')

iterator = util.Iterator(board)
iterator.start()

motor = board.get_pin('d:6:s')

sensorPinNo = 2

sensorPin = board.get_pin('d:' + str(sensorPinNo) + ':i')

print("Nothing is being sensed ")

rlt = sensorPin.read()
while True:
    if rlt:
        print("Sensor has detected something")

        def setServoAngle(angle):
            print("Wiping In Progress")
            for i in range(0, 180):
                setServoAngle(i)
                motor.write(angle)
            for i in range(180, 1, -1):
                setServoAngle(i)
                motor.write(angle)

        print("Program Exit")
        board.exit()

您这里有一些问题，我无法解决，但：

import time
from pyfirmata import Arduino, util

board = Arduino('COM5')

iterator = util.Iterator(board)
iterator.start()

motor = board.get_pin('d:6:s')

sensorPinNo = 2

sensorPin = board.get_pin('d:' + str(sensorPinNo) + ':i')

print("Nothing is being sensed ")

while True:
    rlt = sensorPin.read()
    if rlt:
        print("Sensor has detected something")

        print("Wiping In Progress")
        for i in range(0, 180):
            motor.write(i)
        for i in range(180, 1, -1):
            motor.write(i)

print("Program Exit")
board.exit()

请注意，您的函数没有被调用，最终看起来是多余的

还请注意，此程序不会退出。我不知道退出需要什么条件
