Mar 4, 2025 · Discover the power of the Arduino millis() function for tracking time in your projects. But I also want to have timed cut-off. If the closed condition of K1 is detected, the program ignites LED10 as a side job; after that the normal program flow continues -- the program carries out the events of Step-1. So no, when the millis() value rolls over to 0, your Arduino won’t lock up and your project won’t explode. But I want to find a way to see how can I measure time and be able to pause the timer that was running with it's progress and resume it. Before looking at the code I just made a simple incrementing counter that would reset to 0 every time the lights change. Meanwhile the processor is still free for other tasks to do their thing. time = millis Parameters. If you want to toggle the LED on and off every 2. We use this counter to count time. I've been experimenting different codes but to no avail. This function allows you to perform tasks at specific intervals without blocking the rest of your code, unlike the delay() function. 01. If I press a second time reset millis ( millis() counter becomes = 0 ) If I press it a third time, millis() starts again over from 0; Wiring in attachment. It may also interfere with certain libraries that you want to use in your code. Syntax Oct 2, 2017 · In this thread I will try to explain the principles of using millis () for timing and apply it to some common areas where questions arise.
