Step 1: Supplies

For this instructable you will need the following:

1 arduino (with protoshield to make life easy)
1 LED of any color
1 PIR sensor from Parallax (you can find these at most radio shacks)

how do you get this to send a txt message?
I have made a motion activate camera and I am looking to get it to send me a text message or email when a picture is taken...any thoughts?
thanks

android adk is your friend. if you are into getting into app design you can do it very cheap with a bluetooth adapter

its a nice project sir and very impresive. but sir' i have a question ahm im working with a project that uses wireless senors for security systems with an addressable alarm. can you tech me how these things well be built?

As frenzy has not replied yet, I am already going to ask you to be a bit more specific. Are you interested in just connecting wireless sensors or in building the entire system. In that case, what do you mean with 'adressable alarm'.

Just a question out of interest (forgive me if I am completely off): are you by any chance Filipino? :-)

Did you get a new identity recently, or is this your standard Arduino outfit?
Anyway, always good to read the basics...

No you got it wrong you see he was trying to make arduinos less nerdy but.........it had the opposite affect :I

the arduinos go WOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Sooooooooooo you like driving people crazy?

Mmm, on second thoughts, I guess you're right!

It's a great project if you can make light up sunglasses though

if you are using fritzing, can you send me the download for the pir sensor?

frenzy (author) in reply to account3r2Feb 23, 2011. 5:56 PM

there is no download although adafruit has one in her fritzing tutorials.

i just used the basic component with 3 pins and labeled it

Hey frenzy,
Great tutorial - very well explained.
I could see how a heat sensor and arduino could be used for a project I have been working on. I got the parts but am woefully underexperienced to put it together. I am trying to get a thermal array sensor to run a small motor.
I'm stuck. Got any suggestions on where to go for help?

are you using fritzing?
