You can then use a while with a boolean flag that help you to end the loop or if you prefer, you can keep track of the time by calling the method: millis().
2 sty 2012 · Working from the cookbook on page 38 there is a method called: void blink 2 And then the count function. // blink an LED the number of times given in the count parameter void blink2 (int count) { while (count > 0 ) // repeat until count is no longer greater than zero { digitalWrite (13, HIGH); delay (500); digitalWrite (13, LOW); delay (500);
9 mar 2016 · The number of times loop() runs every second depends on the time taken for the execution of the instructions within loop(). For instance, in your code, the time taken for one loop() is roughly equal to the time taken for the MCU to execute all the statements in loop() (more specifically, the time taken for each operation or function from call ...
8 sty 2018 · void loop() { // put your main code here, to run repeatedly: int sensorState = digitalRead(lightSensor); switch(sensorState) { case 1: while (sensorState == 1) { if(stopTime-startTime<=myDesiredTime && sensorState == 1) { runBuzzer(); stopTime=millis(); } } } }
Opis. Po wykonaniu funkcji setup (), która inicjuje i ustawia wartości początkowe, funkcja loop () (ang. pętla) robi dokładnie to co sugeruje jej nazwa, czyli wykonuje się nieustannie, umożliwiając twojemu programowi na kontrolę zachowania się płytki Arduino poprzez wykonywanie różnych działań i reagowanie na zdarzenia.
