And this goes on. That's it, we have learnt to use millis instead of delay. This way it won’t halt the program for particular interval. Interrupts in Arduino works same as in other microcontrollers.

Let’s Start with the Question If you’ve been using the Arduino for any length of time, you will almost certainly have used the inbuilt millis() function. This returns an unsigned long value, which ...

Three different software timers with millis are used to send something to the serial monitor. An example to change the interval. No extra hardware is required. The time that a led is "on" is different ...

so why would anyone wish to employ the millis() approach? Well, one problem with using the delay() function is that it prevents the Arduino from performing any other task(s). During a delay(), all the ...
