Arduino Basic - LED

准备硬件板子

Genuino 2560

注：

需要自带一根USB type-B 到type-A的转接线

USB line
Genuino 与 Arduino的区别：

Genuino is Arduino.cc’s sister-brand created by Arduino co-founders Massimo Banzi, David Cuartielles, Tom Igoe, and David Mellis, the Arduino.cc team and community.This brand is used for boards and products sold outside the US.

下载软件 IDE

下载 Arduino IDE

安装驱动

插上USB链接的板子，提示驱动未安装如下：

Driver not installed

更新驱动程序软件

浏览计算机以查找驱动程序软件

选择Arduino IDE的解压路径下的drivers文件夹，并单击下一步：

选择IDE所在目录的`drivers`子目录

等待安装完成

此时，再看计算机管理，驱动正确安装

COMx

运行跑马灯

打开arduino.exe，并打开跑马灯例程

Blink

打开工具，并选择Arduino对应的板子型号和串口

稍微修改下两灭灯的时间比，如下亮3s，灭1s：

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the Uno and
  Leonardo, it is attached to digital pin 13. If you're unsure what
  pin the on-board LED is connected to on your Arduino model, check
  the documentation at http://www.arduino.cc

  This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin 13 as an output.
  pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(3000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}
