Arduino delay function performs the function of pausing the execution for the time interval set by the user. The syntax of the delay function is delay(). The time interval for the delay is given in milliseconds. Therefore, to set the time for the delay you would have to multiply the requi...
无涯教程-Arduino - delay()函数 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)。 delay - 语法 delay (ms) ; 1. 其中, ms 是暂停的时间(以毫秒为单位)(无符号长)。 delay - 示例 /* Flashing LED * --- * Turns on and off a light emitting diode(L...
下面是一个Arduino示例: void setup() { pinMode(LED_BUILTIN, OUTPUT); } void loop() { digitalWrite(LED_BUILTIN, HIGH); // LED点亮 delay(1000); // 延迟1秒 digitalWrite(LED_BUILTIN, LOW); // LED熄灭 delay(1000); // 延迟1秒 } 2. 按钮去抖动:按钮去抖动是另一个常见的使用delay的场景...
在arduino程序中 delay(1)是指延时1毫秒 delaymicroseconds(1)是指延时1微秒,而实际上,因为硬件本身性能的限制,1微秒的延时可能会出现偏差的如... delayMicroseconds和delay有什么区别 你应该使用delay()代替。 此函数在3微秒以以上工作的非常准确。我们不能保证,delayMicroseconds在更小的时间延时准确。 Arduino0018版本...
这delay()函数是一个非常有用的函数,几乎在所有示例中都会看到它。但是,为了提高代码效率,它并不是最好的选择,因为它会阻止 Arduino 在延迟期间执行任何操作。 为此,我们可以使用millis()功能。 millis() 这millis()函数稍微高级一些,但资源非常丰富。它允许您同时发生多个事件,而无需暂停程序。这是通过测量自程序...

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!
* pin, in intervals of 2 seconds. * */ int ledPin = 13; // LED connected to digital pin 13 void setup() { pinMode(ledPin, OUTPUT); // sets the digital pin as output } void loop() { digitalWrite(ledPin, HIGH); // sets the LED on ...

If you're used to working with software like arduino, you may think you can just use something like, delay(1000), to create a 1-second delay in a program. However, this is not how it works when actually programming a real-life microcontroller. ...
