- millis() | Arduino Documentation
millis() is incremented (for 16 MHz AVR chips and some others) every 1 024 milliseconds, then incremented by 2 (rather than 1) every 41 or 42 ticks, to pull it back into sync; thus, some millis() values are skipped For accurate timing over short intervals, consider using micros() millis()
- Using millis () for timing. A beginners guide - Arduino Forum
To use millis () for timing you need to record the time at which an action took place to start the timing period and then to check at frequent intervals whether the required period has elapsed
- [SOLVED] How to correctly use millis () for delay - Arduino Forum
You're missing the point, using millis () correctly allows you to wait until the time is appropriate while freeing up the processor to do other things Using while () like that you might as well just use delay (), you've just re-created delay () in a different way
- Millis () roll over - General Guidance - Arduino Forum
Begin timing an interval by grabbing the value of millis (), later determine the elapsed time by subtracting that saved value from the current, new value returned by millis ()
- Millis () to hours, minutes, seconds, and milliseconds
if(minutes == 3 seconds == 36 remainder == 476) { digitalWrite(ledPin, HIGH); } This will only be true if you are very very lucky and just happen to call millis () at this exact time
- Resetting Millis () to zero, reset clock - Arduino Forum
Rollovers notwithstanding, millis () is suitable for any interval comparison, provided that the interval is < 49 71 days This is simple enough to simulate, so I offer the following example Please run it and post the results for us
- How to use millis as a timer after a button press - Arduino Forum
My thought was to set startTime as whatever millis () is when the button is pressed, then subtract by that amount in the while loop so it's effectively zero However, the motor doesn't stop running, so I think what's happening is that the startTime variable is incrementing along with millis ()
