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...

The Arduino delay function is an Extremely Useful function which you can use to get small delays. However, sometimes it's not the right function to use � there is another!

I'm also willing to bet you used thedelay()function to define the intervals between the light turning on and off. 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 yo...
