好的,我可以回答这个问题。首先,您需要连接一个超声波模块和一个舵机到Arduino板上。然后,您需要编写一个程序来读取超声波模块返回的距离,并根据所读取的距离来控制舵机的角度位置。具体的流程可以参考以下代码:
```
#include <Servo.h>
Servo myservo; // create servo object to control a servo
int echoPin = 2; // define the pins
int trigPin = 3;
void setup() {
pinMode(trigPin, OUTPUT); // set the trigPin as an output
pinMode(echoPin, INPUT); // set the echoPin as an input
myservo.attach(9); // attaches the servo on pin 9 to the servo object
Serial.begin(9600); // start serial communication at 9600 bps
}
void loop() {
long duration, distance;
digitalWrite(trigPin, LOW); // set the trigPin low
delayMicroseconds(2); // wait for 2 microseconds
digitalWrite(trigPin, HIGH); // send a 10 microseconds pulse to the trigPin
delayMicroseconds(10);
digitalWrite(trigPin, LOW);
duration = pulseIn(echoPin, HIGH); // read the duration of the incoming pulse on the echoPin
distance = duration * 0.034 / 2; // convert the duration to distance in cm
Serial.print(distance); // print the distance on the serial monitor
Serial.println(" cm");
if (distance < 20) { // if the distance is less than 20 cm
myservo.write(180); // move the servo to 180 degrees
}
else { // if the distance is greater than 20 cm
myservo.write(0); // move the servo to 0 degrees
}
delay(100); // wait for 100 milliseconds
}
```
这个程序实现的功能是:当超声波模块返回的距离小于20厘米时,将舵机的角度位置设置为180度,否则为0度。您可以根据您的具体需求进行修改。
