在Arduino编程中，delay(200)会让程序暂停执行200毫秒，相当于0.2秒。这个函数常用于需要暂停一段时间的场景，比如等待传感器读数稳定或使LED闪烁。在Keil中进行调试时，如果设置断点并运行，可以准确计算出这段延迟时间的具体时长。函数delay的基本用法为void delay(unsigned milliseconds)，这里的milliseconds...
// constants won't change: const long interval = 1000; // interval at which to blink (milliseconds) void setup() { // set the digital pin as output: pinMode(ledPin, OUTPUT); } void loop() { // here is where you'd put code that needs to be running all the time. // check t...
先连接电阻的一端到Arduino的PIN13引脚。再连接LED灯的长引脚(正脚,也叫阳极)到电阻的另一端。最后连接LED灯的短引脚(负脚,也叫负极)到Arduino的GND引脚。如图所示 大部分Arduino开发板上面就有一个LED灯连接到PIN13。如果你不连接硬件就运行这个例子,你应该也可以看到LED闪烁。 原理图 你插好电路板,连上电脑...
The Arduino delay() function allows you to pause the program execution for a specified number of milliseconds, which is useful when you need to synchronize events or actions with real-world timing. Note:This is a super-important-point:Pausingmeans the processor stops doing anything! - you'll ...
(milliseconds)voidsetup(){// set the digital pin as output:pinMode(ledPin,OUTPUT);}voidloop(){// 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 difference// between the current time and last...
delay（200）相当于0.02秒 在keil中调试时设置断点后，运行可以计算出你需要的时间的 1、函数名: delay 功 能: 将程序的执行暂停一段时间(毫秒)（该函数是TC下特有的函数，VC下应使用Sleep()函数）用 法: void delay(unsigned milliseconds);2、WinAVR avr/delay函数的用法：在avr GCC的函数库中...
log("This message is displayed after 500 milliseconds"); }, 500); 5、总结示例之间的差别,说明后续相关问题的解决思路: delay(500)的含义是延时500毫秒,这一点在不同编程环境中通常是通用的。然而,不同编程环境对delay函数的支持和实现方式可能有所不同。因此,在使用delay函数时,需要查阅相应编程环境的文档...
Make an Arduino delay for 1 minuteIf you want to make your Arduino sleep for 1 minute, or for multiple minutes, then it’s quite easy.Take the number of minutes, multiply it by 60 to get the number of seconds, and then multiply it by 1000 to get the number of milliseconds....
millis() function returns the number of milliseconds passed since the Arduino board began running the current program. It cannot be used to add delay to your code. For adding delay, you have to use delay() function. Reply Options 2 posts ...
