控制LED闪烁:代码通过控制数字引脚13(大多数Arduino板上连接了一个内置LED)的电平高低,使LED灯以1秒亮、1秒灭的频率不断闪烁。 代码逐行解释 1. 注释部分 功能:让一个LED灯每秒闪烁一次,即亮1秒,灭1秒,不断重复。 /* Blink Turns on an LED on for one second, then off for one second, repeatedly. This...
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...
pinMode(led, OUTPUT); } // the loop routine runs over and over again forever: void loop() { digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(led, LOW); // turn the LED off by making the voltage LOW delay...
LED灯闪烁实验 1.运行Arduino 2.选择IDE开发板。“工具 > 开发板”,然后选择您的开发板。3.选择“文件 > 示例 > 1.Basics > Blink”,打开 LED 闪烁示例 sketch。4.从“工具 > 端口”菜单中选择开发板的串行设备。选择 COM 端口后,COM 端口编号将显示在 Arduino 右下角。
/* 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...
这就是Blink的代码: /*BlinkTurns 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:intled =13; ...
然后，我们需要将先前保存的blink验证ID放入auth []数组中。char auth[] = "HoLYSq-SGJAafQUQXXXXXXXX...
我们可以先看看arduino官方为我们提供的示例——Blink 你可以先看看这个示例的注释,或者直接开始看代码。 你也可以直接向arduino上传这个示例, 这里我把代码放到这里 注释应该可以说是解释的比较详细了,我在这里大概翻译加解释一下 // the setup function runs once when you press reset or power the board ...
Blink 闪烁 Turns an LED on for one second, then off for one second, repeatedly. 点亮LED 1 秒钟,然后熄灭,重复上述操作。 Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to ...
