Alarm buzzer

[riggeek]

Was thinking about putting my alarm buzzer on the ato Hi flow switch input. from everything I have read it looks like this could be done,

I done some reading on the forum, and a programming book, but still am not sure how i would do it with the reef angel.

Can some one post a sample code so i can read up on this more.

Thanks

Try this:

Code: Select all

pinMode(highATOPin,OUTPUT);
digitalWrite(highATOPin,HIGH);
