Question

错误是：

Arduino: 1.8.5 (Windows 10), Board: "Arduino/Genuino Uno"

C:\Users\User\Downloads\BLUETOOTH_CAR\BLUETOOTH_CAR.ino:1:21: fatal error: AFMotor.h: No such file or directory

 #include <AFMotor.h>

                     ^

compilation terminated.

exit status 1
Error compiling for board Arduino/Genuino Uno.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

我的代码是：

#include <AFMotor.h>
AF_DCMotor right_motor(1, MOTOR12_8KHZ);
AF_DCMotor left_motor(2, MOTOR12_8KHZ);

String readString;

void setup() {
  Serial.begin(9600);
  right_motor.setSpeed(250);
  left_motor.setSpeed(250);
}

void loop() {
  while(Serial.available()){
    delay(50);
    char c=Serial.read();
    readString+=c;
  }
  if(readString.length()>0){
    Serial.println(readString);
    if (readString =="FORWARD"){
      right_motor.run (FORWARD);
      left_motor.run (FORWARD);
      delay(500);
    }
    if (readString =="BACKWARD"){
      right_motor.run (BACKWARD);
      left_motor.run (BACKWARD);
      delay(500);
    }
    if (readString =="LEFT"){
      right_motor.run (FORWARD);
      left_motor.run (BACKWARD);
      delay(500);
    }
    if (readString =="RIGHT"){
      right_motor.run (BACKWARD);
      left_motor.run (FORWARD);
      delay(500);
    }
    if (readString =="STOP"){
      right_motor.run (RELEASE);
      left_motor.run (RELEASE);
      delay(500);
    }

    readString="";
  }
}

Answer 1

可能是因为编译器无法找到头文件。确保将带头文件的库移动到默认的Arduino库文件夹，或者将库移动到与Arduino代码相同的目录，然后尝试：

#include "AFMotor.h"

为什么我的代码显示这些错误？
