Monitoring my two garage doors is my first official OAK project. Basically it is up and running, but I'd like to enhance the project if I can. What I'd like is to monitor the doors with an app on my Android phone and better than that, I'd like the system to send me a door open text message if I put it into a special mode, such as when I'm away from home.
My code is below. Please feel free to offer comments and ideas, especially on how to make it better.
/*Program to monitor double garage doors

* To monitor my two garage doors, I installed magnetic switches
* beside each door. The magnets are mounted on the doors themselves.
* When the doors are closed, the magnets are right next to the
* switches and that causes the switch to close. On the OAK, I have
* one switch wired between P3 and GND and the other between P4 and GND.
* I configured P3 and P4 as INPUT_PULLUP so that when the doors open, the
* inputs are pulled high.

//flash LED twice

/*
* Get status of door switches. This is useful to see the actual
* result of the digitalRead calls. They will give you 0 or 1. After
* you verify that your switches are working, you can comment it
* out like I did.
