当红外传感器感应到某些东西时，我的伺服电机没有移动

Question

I am trying to get the servo motor to turn 180 degrees and then back to 0 degrees when the IR sensor senses something 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()

I have: Arduino uno, servo motor, IR sensor, Buzzer, LED, Resistors, Breadboard, Jumper wires

You have a few problems here, not all of which I can fix, but:

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()

Note that your function wasn't called and in the end seemed redundant.

Also note that this program does not exit. I don't know what condition is needed to exit.
