Arduino IF Statement Code Examples by Lewis Loflin Video for this page: Arduino Comparison IF Operators Think of a micro-controller as a box full of basic logic circuits, gates, etc. To control the "box" we have to tell it what hardware to use. We must tell the "box" how to manipulat...
另外你还可以在菜单 File/Examples/01.Basics/Blink 中直接调出此代码。代码中你要做的第一件事就是配置 LED_BUILTIN 引脚为输出引脚,如下: pinMode(LED_BUILTIN, OUTPUT); 在主循环代码内,你需要用这句代码点亮 LED: digitalWrite(LED_BUILTIN, HIGH); 这会对 LED 阳极供电 5V。这就会使 LED 的两只引脚...
VS Code 使用通义灵码插件和 PlatformIO 插件快速生成 Arduino 框架下的 LED 闪烁代码 一、引言 1.1 从一个有趣的LED闪烁说起 LED闪烁:简单、有趣,是嵌入式系统学习的良好开端 🔥 应用广泛,从指示灯到显示屏,LED无处不在 💡 1.2 Arduino框架让开发变得简单有趣 ...
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 connected on most Arduin...
接下来通过一个Arduino开发环境中LED灯闪烁的例子(Blink)来简单应用一下这些按钮。在Arduino Uno板的13号引脚上已经带了一个LED灯,Blink程序就是控制这个LED灯闪烁。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。点击“校验”按钮实现程序的编译,等待一会儿后状态栏会提示Done ...
Note that the LED will only stay on while the button is depressed, and will shut off when you release it. Here’s the full source code:int btstate = 0; void setup() { pinMode(13, OUTPUT); pinMode(11, INPUT); } void loop() { btstate = digitalRead(11); if (btstate == HIGH...

这个LED是安装在Arduino板上的,通常被称为“L”LED,因为它在板上是这样标记的。 这个LED的位置在下面的Arduino Uno和Leonardo的图片上用红色圈出。 NANO 是一块超小尺寸的Arduino开发板,使用和UNO一样的主控芯片,可以看作是UNO的缩小板,LED灯的位置职下图所示: 这块板在“兑悦物联小店”里有哦! 学习Arduino所...
