Hi, I am updating my burglar alarm, and need to operate two relays triggered by the alarm output (12 volt). I want to learn the programming, but don't have time to focus on it at the moment.
I have a new Arduino board, and the relay shield that fits over it. When the alarm is triggered I need one relay to close for 3 seconds then then go back to normally open. After a 3 second delay I need the second relay to close for 4 seconds then open. After one minute I'd like for it to loop one more time.
