delay () function delay()函数的工作方式非常简单。 它接受单个整数(或数字)参数。 该数字表示时间(以毫秒为单位)。 程序应该等到遇到此函数时转到下一行代码。 但问题是,delay()函数不是让程序等待的好方法,因为它被称为“阻塞”函数。 delay() function Syntax delay (ms) ; 其中,ms是暂停的时间(以毫秒为...

pin, without using the delay() function. This means that other code can run at the same time without being interrupted by the LED code. The circuit: * LED attached from pin 13 to ground. * Note: on most Arduinos, there is already an LED on the board that's attached to pin 13, s...
How to use delay() Function with Arduino. Learn delay() example code, reference, definition. Pauses the program for the amount of time (in milliseconds) specified as parameter. What is Arduino delay().
Arduino开发:delay(1000)会使单片机暂停1秒,期间CPU处于阻塞状态,适合简单实验但不适用于多任务场景。 Python脚本:需调用time.sleep(5)实现5秒延迟,这种非阻塞式延迟更适用于后台进程管理。 前端交互:JavaScript中可用setTimeout(function(){}, 3000)实现3秒后执行代码,用于页面元素动态加载...
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

More knowledgeable programmers usually avoid the use of delay() for timing of events longer than 10’s of milliseconds unless the Arduino sketch is very simple...
But here's the thing: while delay is handy for basic demonstrations of how Arduino works, you really shouldn't be using it in the real world. Here's why – and what you should use instead. How Delay() Works The way the delay() function works is pretty simple. It accepts a single...
