零基础入门学用 Arduino 教程 – 6 Arduino程序 – 程序结构

本集教程主要内容
+ 上传Arduino程序并让程序在Arduino中运行
+ 观察Arduino 内置LED的工作情况并思考这一结果是如何通过程序实现的

本节课程示例程序:


/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
  反复的点亮LED一秒钟，然后关闭LED一秒钟。

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO 
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino model, check
  the Technical Specs of your board  at https://www.arduino.cc/en/Main/Products
  很多Ａｒｄｕｉｎｏ开发板上带有一个你可以控制的ＬＥＤ． 在UNO, MEGA 和 ZERO型号的开发板上，
  这个ＬＥＤ连在了引脚１３上。 在MKR1000型号的开发板上，这个ＬＥＤ连在了引脚６上。无论使用哪
  种型号的开发板，LED_BUILTIN可以代表正确的LED引脚编号。
  
  This example code is in the public domain.
