There are ways to Wir nutzen fortan die millis()-Methode, um die Anzahl der Millisekunden seit Starten des Arduino-Boards zu erhalten. 17. Calling the millis() function in the Arduino sketch returns the number of milliseconds that have elapsed since you start to run the program. The maximum value for the Arduino millis() function is 2 32-1 which is 4,294,967,295. Delay itu adalah sebuah sub-routine yang tugasnya membuat sibuk prosesor dalam jangka waktu yang telah ditentukan, jadi ketika lu pake fungsi delay(2000) arduino akan sibuk selama dua detik. Simple multitasking on the Arduino. Des Weiteren speichern wir in einer Variable bei welcher Anzahl von Millisekunden das letzte Update beim LED-Status gemacht wurde. Keine. In practice, an Arduino cannot execute tasks in parallel, but it can arrange and execute a number of tasks one after the other in a very short space of time. Arduino time is kept in unsigned long variables, both the millis() and micros() functions return unsigned long. When a sensor is triggered, it waits for a keyboard input, and if a correct code isn't entered, it sounds an alarm and sends an SMS to 5 phone numbers.
