作者:iamlaosong1、一般延时一个应用接口需要限制运行速度,需要在循环中加个延时函数,这个延时不需要多么精确,要求有个几秒延时,网上用的比较多的就是用Timer函数编写,Timer是VBA自带的函数,用起来比较方便,一般程序如下:'延时程序Sub delay(T As Single) Dim time1 As Single time1 = Timer Do ...
以下代码用 millis()函数来闪烁LED灯,如果开发板开始运行,会返回微秒的数值 /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital pin, without using the delay() function. This means that other code can run at the same time without being interrupted by th...
// Add a 5-second time delay Serial.println("Delay Started"); delay(5000); Serial.println("Delay Finished"); Serial.println("..."); } 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 3...

在这个示例中,首先通过WiFi.begin()函数连接到WiFi网络,然后使用delay(1000)函数延迟1秒,最后通过ESP8266的.connect()函数建立与服务器的连接。 需要注意的是,延迟时间的设置应根据具体情况进行调整。如果连接过程中出现连接超时或连接不稳定的问题,可以适当增加延迟时间。同样,如果网络连接速度较快和稳定,可以...
这是来自IDE的BlinkWithoutDelay示例程序: /* Blink without Delay Turns on and off a light emitting diode (LED) connected to a digital 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: * Use...

The following code is trying to control the delay time by passing a variable to the delay function which is changed when a button is pressed. #defineLEDLED_BUILTIN #defineINPUT5 ///voidloop(){ uint16_tdly=200;delay(dly);digitalWrite(LED,HIGH);delay(dly);digitalWrite(LED,LOW);if(digital...
delay(20);if(buttonState==HIGH && buttonStateOld==LOW)//按钮状态发生变化{ buttonHoldTime= millis();//用millis()时间函数来记时,该函数最长记录时间为9小时22分,由于本程序最多记录60分钟,所以可以使用buttonStateOld =buttonState;if(onoff==HIGH)//当进入定时设置状态时{if(j>59) ...
