The maximum value for the Arduino millis() function is 2 32-1 which is 4,294,967,295. millis() function does not block the entire code just like delay. Data Types. Authenticate people using their Updated Sep 8, 2024 Never use delay(), and try to never use millis() and micros() as well. I think that I have problem when millis go back to zero. However, they can really complicate things when you’re trying to multitask your Arduino. For example, you may want a servo to move every 3 seconds, or to send a status update to a web server every 3 minutes. And also the fundamental limitations of the micros() function and how to overcome the micros() overflow (rollover) issue in your Arduino projects. • Timer1- For the working of servo May 28, 2020 · Good morning, I use a push button I'd like if we press the first the millis() counter starts. If you’re not aware of these, you might end up using delay() instead, which won’t always work that well (if at all). The second millis is used to measure the passing time, and if the time exceeds 400ms, then the robot exist the while loop. We’ll create a couple of Arduino-Timer Library Example Projects in this tutorial to practice what we’ll learn all the way through. Courtesy of All About Circuits.
