Arduino Programming Basic - Funcation

RonWang1年前 (2024-04-15)电子编程519

Arduino 程序基础,介绍Arduino程序的基本组成,第一部分编写了10个例子,关于变量及变量名称,串口监视器,if循环,for循环,while循环等。第二部分介绍了函数,全局变量,局部变量和静态变量,数据类型,Bollean运算,注释语句等。

Funcations 函数

Functions in C and arduino

Flash 函数 2-1

int ledPin=13;
int delayPeriod =200;

void setup()
{
pinMode(ledPin,OUTPUT);
}

void loop()
{ 
  flash(20, delayPeriod);
  delay(3000);
 }
 
 void flash(int numFlashes, int d)
 {
  for( int i=0; i<numFlashes; i++)
   { digitalWrite(ledPin,HIGH);
     delay(d);
     digitalWrite(ledPin,LOW);
     delay(d);
  }
  }

函数的返回值 Return 2-2

int centToFaren(int c)
{
int f= c*9/5+32;
return f;
}
//函数调用

int pleasantTemp =centToFaren(20);

Code written on Arduino IDE Software
