   Is a Millis rollover a problem?

   • Most Arduino programs only have to manage events that span relatively short durations, like debouncing a button for 50 ms, or turning a heater on for 12 hours... Then, and even if the program is meant to run for years at a time, the millis rollover should not be a concern.

   What is Arduino Millis?

   • Without further ado, let’s get right into it! The Arduino millis () is a timer-based function that returns to you the time elapsed (in milliseconds) since the Arduino board was powered up. Which can be used to create a time base for various events in your applications (like LED blinking or whatever).

   What is the difference between Arduino Millis & delay function?

   • As the delay () function does actually block the CPU and badly affects the responsiveness of your application at the end. The Arduino millis () function, on the other hand, can be used to get and compare time stamps to achieve different timing requirements as per your application needs.

   What is the maximum value for the Arduino Millis() function?

   • The maximum value for the Arduino millis () function is 232-1 which is 4,294,967,295. This turns out to be 49.71 days before the millis () variable reaches overflow and rollovers back to zero and starts counting up again.

   Jun 12, 2015 · If you want it to go through the millis overflow over and over again, like Phil Connors reliving Groundhog Day, you can put this inside loop(): // 6-second time loop starting at rollover - 3 seconds if (millis() - (-3000) >= 6000) setMillis(-3000);

   arduino.stackexchange.com › questions › 22994

   Unfortunately, as far as I can tell, millis() and micros() cannot be manually reset. Obviously, I could save a time stamp whenever the event occurs; however, I want to avoid overflow problems (micros() will overflow every ~71 minutes, and millis() will overflow every ~50 days).
