I did a code in which when you press a button, a delay starts an then a servo moves. But what if I wanted to set another button to cancel the previous sequence (the delay one). I used an if to programme the button in order to start the delay...

If you use delay() the processor is tied up during the duration of the delay(). You can't read the button until the delay is finished. How to use millis() for timing: Several things at a time. Beginner's guide to millis(). Blink without delay().
