Arduino面向对象(C++)编程开发示例程序

• 代码

class Led {
  public:
    Led();//构造函数
    ~Led();//析构函数
    void on();
    void off();
};
 
Led::Led(){
  Serial.println("Led Object Created.");
  pinMode(2, OUTPUT);
}
 
Led::~Led(){
  Serial.println("Led Object Deleted.");
}
 
void Led::on(){
  digitalWrite(2, HIGH);
}
 
void Led::off(){
  digitalWrite(2, LOW);
}
 
void setup() {
  Serial.begin(9600);
  Led myLed; //创建类的对象，同时执行构造函数里面的内容。
  Serial.println("Hello, this is from Setup()");
  for(int i = 0; i < 3; i++){
    myLed.on();
    delay(1000);
    myLed.off();
    delay(1000);
  }
}
 
void loop() {
 
}
