This example code is in the public domain. */ 2. 变量定义 定义了一个变量led,并将其赋值为13。这表示代码将操作数字引脚13,大多数Arduino板上,数字引脚13连接了一个内置的LED灯。 // Pin 13 has an LED connected on most Arduino boards. // give it a name: int led = 13; 3.setup()函数 vo...
UNO板上标有L的LED。这段测试代码就是让这个LED灯闪烁。 插上USB线,打开Arduino IDE后,找到“Blink”代码。 通常,写完一段代码后,我们都需要校验一下,看看代码有没有错误。点击“校验”。 下图显示了正在校验中。 校验完毕! 由于是样例代码,所以校验不会有错误,不过在以后写代码的过程中,输入完代码,都需要校验...
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...
/* 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 Arduino boards. // give it a name: int led = 13; // the setup routine runs once when you press reset: void...
LED was updated // constants won't change: const long interval = 1000; // interval at which to blink (milliseconds) void loop() { // here is where you'd put code that needs to be running all the time. // check to see if it's time to blink the LED; that is, if the ...
2、Blink.ino中用到的几个函数: ① pinMode(pin,mode) : 将指定的引脚配置为输入或输出 - pin : 所需要设置的引脚号 - mode : INPUT/OUTPUT(pinMode也可以是INPUT_PULLUP,使用引脚内置的上拉电阻) pinMode(LED_BUILTIN, OUTPUT); ② digitalWrite(pin,HIGH/LOW) : 数字引脚输出,HIGH表示高电平(5v),LO...
使用通义灵码生成代码的提示语:"用Arduino实现ESP32的LED闪烁,LED接在GPIO2上" void setup() { pinMode(LED_BUILTIN, OUTPUT);// GPIO2是ESP32的板载LED Serial.begin(115200);// 初始化串口通信 Serial.println("ESP32 LED Blink Test"); }
1、blink代码实验 点击file菜单下EXAMPLES--011.Basics--Blink,就可以看到Blink程序已经加载到程序编辑区。因为使用的端口不同,略加修改如下: /*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 connecte...
五)blink程序 Blink示例程序如下: /* Blink Turns on an LED on for one second,then off for one second,repeatedly. This example code is in the public do main. */ //Pin13 has an LED connected on most Arduino boards. //give it a name: ...
