我一直在尝试在arduino上对这个运动传感器进行编程，以便在检测到时移动伺服系统，但它似乎根本不起作用我什至买了另一个，但仍然不起作用我尝试根据中间线的intrent指令链接它适用于 rthe boutput 和右侧 GND 左侧 V5，甚至反之亦然，所有方法似乎都不起作用，正如我所说，代码的想法非常简单，我什至向 chatgpt 询问了代码，在这里，它不起作用，我不知道出了什么问题：
type #include <Servo.h>
// Pin connections
const int motionSensorPin = 2; // Connect the motion sensor output pin to Arduino digital pin 2
const int servoPin = 9; // Connect the servo signal pin to Arduino digital pin 9
// Servo configuration
Servo myServo; // Create a servo object
// Variables
int servoPosition = 0; // Initial position of the servo (adjust as needed)
int motionState = LOW; // Current motion state (LOW: no motion, HIGH: motion detected)
int motionSensorState = LOW; // Previous motion sensor state
void setup() {
myServo.attach(servoPin); // Attach the servo to the specified pin
pinMode(motionSensorPin, INPUT); // Set the motion sensor pin as input
myServo.write(servoPosition); // Set the initial position of the servo
}
void loop() {
motionSensorState = digitalRead(motionSensorPin); // Read the motion sensor state
if (motionSensorState != motionState) {
if (motionSensorState == HIGH) {
servoPosition = 30; // Set the servo position to 90 degrees when motion is detected
servoPosition = -30;
} else {
// Set the servo position to 0 degrees when motion stops
}
myServo.write(servoPosition); // Move the servo to the desired position
motionState = motionSensorState; // Update the motion state variable
}
}here

我不确定这是否是代码逻辑错误或硬件或连接错误，您可以建议这是我第一次遇到这种传感器，我仍然怀疑它是否可以工作
这段代码对我有用。我从您的代码中更改了它，以便控制所设置的相同伺服系统。它根据 PIR 向舵机写入不同的值，以便舵机移动。
