Pin 2 is an interrupt enabled pin. When pin 2 goes high an interrupt service routine (ISR) is called. This can stop the dolly even when it is in between a cycle. I probably could have left out connecting the button to A2 (I don't remember why I didn't do that, probably for the sake of uniformity).Interrupts are quite useful for such things, make sure to read more about interrupts.
Sure, I would love to help you!What do you think is the problem? Test each and every part individually to make sure it works.
