The Arduino stores the current millis value in an internal 4-byte register, which is driven by a timer that increments it every millisecond. Once this register reaches 4,294,967,295 in decimal ...

This example shows how to timestamp events with millis (). millis_overdone.ino This sketch runs 400 millis timers at the same time on a Arduino Uno, or 7000 millis timers on a Arduino Zero or MKR ...

In my previous column, we discussed the fact that the time returned by the Arduino’s millis () function will overflow (wraparound) to 0 every 49.71 days. As part of those discussions, we created the ...
