这段代码是Arduino编程语言的一个经典示例,用于控制一个连接在数字引脚13上的LED灯,使其以每秒闪烁一次的频率持续闪烁。 /* Blink Turns on an LED on for one second, then off for one second, repeatedly. This example code is in the public domain. */ // Pin 13 has an LED connected on most Ar...
{ // declare pin 9 to be an output: // pinMode(led, OUTPUT); pinMode(LED_PIN, OUTPUT); pinMode(LED_PIN_2, OUTPUT); pinMode(LED_PIN_3, OUTPUT); } /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() ...

入手的Arduino型号是Arduino Nano V3.0 首先接上USB电源,绿灯常量,红灯闪烁,显然里面已经内置了一个demo程序。 可以看出实际上Arduino自带了一个LED灯,我们可以用于开发调试。 好,进入正题~ 1、IDE安装 http://pan.baidu.com/s/1b4jPX8 2、驱动安装

No, no, no WiFi board and an L E D. And we're going to go to a Web page that's been created by the Arduino. You know, WiFi and using hyperlinks we're going to turn an led on and off. Wyness is significant. Wyness is important is because this is showing you you can connect...
