No entanto, certas coisas continuam a acontecer enquanto a função delay() está controlando o microcontrolador, porque a função delay não desativa 在本教程中，您将学习如何使用Arduino-delay()函数delay()函数的工作方式非常简单。它接受一个整数（或数字）参数。这个数字代表时间（以毫秒为单位）。当程序遇到此函数时，它应该等待，直到转到下一行代码。然而，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 Arduino delay peuvent souvent être trouvés dans les programmes. 20th Dec 2021 update: added PinFlasher class and example (included in SafeString library V4. With delay(), you can wait up to 429497295 ms, or about 49. Arduino R4 WiFi DHT. The program should wait until moving on to the next line of code when it encounters this function. For alternative approaches to controlling timing see the Blink Without Delay sketch, which loops, polling the millis() function until enough time has elapsed. 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. Bestimmte Dinge laufen jedoch weiter, während die delay ()-Funktion den Atmega-Chip steuert, da die delay ()-Funktion Interrupts nicht deaktiviert. . It waits a number of milliseconds.

However, the problem is, the delay How to use delay() Function with Arduino. gatsby-image-wrapper [data-placeholder-image]{opacity:0!important}</style> <iframe src Here, delay(1000); halts the program for 1000 milliseconds (1 second) before continuing execution. Create another global variable to store the duration you want between 2 actions. Discover the power of millis() and delay() functions in Arduino through practical examples. delay()関数を使ってLEDを点滅させることは簡単だし、多くのスケッチではスイッチのチャタリングを防止するために少しの遅延を利用しているが、スケッチでdelay()を利用することには重大な欠点がある。 delay() hält das Programm für die angegebene Zeit in Millisekunden an. Previous Quiz. In dieser Zeit kann kein anderer Befehl ausgeführt werden. delay 함수 동안 센서 읽기, 수학 계산, 핀 다루기가 중단되므로, 결과적으로, 거의 모든 다른 작업이 멈춘다. It accepts a single integer (or number) argument. 13+) 6th Jan 2020 update: The millisDelay class is now part of the SafeString library V3+. See the syntax, parameters, example code, and notes on the drawbacks and alternatives of using delay () for timing.
