在Arduino中,平时的Hello World叫做Blink,能用来判断开发环境是否可用,程序的效果是使开发板上13号引脚的LED灯反复点亮又熄灭 需要注意的是,新版IDE自带例程使用的是宏LED_BUILTIN,在大部分arduino开发板上,这个宏定义对应的是13号引脚: #define LED_BUILTIN 13 1. 以上是基本的语法,但要真正地上手Arduino,还需要...
>>> def hello_world(): message = "Hello World" print(message) >>> hello_world() Hello World 在这段代码中,我们创建了一个简单的函数,它只打印消息“Hello World”。现在,每当我们想要打印该消息时,我们只需调用该函数。>>> hello_world() Hello World 为了让事情更有趣一点,我们可以为函数提供数据...
