11/21/2023 0 Comments Arduino delay time![]() However, as we’re using unsigned numbers for both variables and the result is also an unsigned number, the subtraction will give the absolute difference between (T2 & T1). In this case, T2 is no longer larger than T1, and doing the subtraction ( T2 – T1) is expected to result in a huge negative number. However, at the overflow time, the T1 will have something like (4,294,967, 280) and T2 has passed the (4,294,967, 295) limit and rolled back to zero and now has a value of 84. ![]() And your application will keep running smoothly and toggle the LED every TimeInterval as you’ve programmed it to. Here is the full code listing for this example.Īlways T2 (the current time stamp) will be larger than T1 (the previous timestamp). This example project is acting more like a simple scheduler’s dispatcher in my opinion. You can build on top of this example and create a simple small scheduler. There is no strong reasoning behind choosing those actions for the 3 tasks specifically, I just wanted to demonstrate how to attempt multitasking on Arduino using the millis function.
