解释了变量的声明和命名规则，以及函数的定义和在程序中的重要性。在此示例中，我们使用了int类型，即整型，它可以表示一个介于-32768和32767之间的数值。变量的类型取决于我们存储的内容。在此例中，ledPin表示LED与Arduino的数字引脚10相连。在代码中，我们定义了两个重要的函数：setup和loop。函数在Arduino编程中的重要
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...

In the previous tutorial, we learned to blink LED by using the delay method. That method blocks Arduino from doing other tasks. In this tutorial, we are going to learn another method to blink LED without blocking other tasks. The detail instruction, code
Blink*/// 在大多数Arduino控制板上 13号引脚都连接了一个标有“L”的LED灯// 我们给13号引脚设置一个别名“led”int led = 13;//在板子启动或者复位重启后, setup部分的程序只会运行一次void setup(){ // 将“led”引脚设置为输出状态 pinMode(led, OUTPUT);}//setup部分程序运行完后,loop部分的程序...
setup():setup()函数只运行一次,用来启动Arduino控制器,将运行中不改变的数值和属性固化到芯片中。The setup function runs once when you press reset or power the board. loop() : loop()函数循环执行,直到按下reset键或者移除电源。 2、Blink.ino中用到的几个函数: ...
Arduino Code This code is used to blink an LED connected with pin number 22 with a delay of one second. void setup() { pinMode(22, OUTPUT); // Set GPIO22 as digital output pin } void loop() { digitalWrite(22, HIGH); // Set GPIO22 active high ...
