Ok. You already know I'm using a BASIC Stamp 2 by parallax blueroomelectronics. Anyways, for everyone else out there, that's what I am using. I am also using a radioshack 6-12VDC Alarm Buzzer. The main component of the whole setup is a Parallax PIR for the motion sensor. I wrote a custom code for the Stamp. Just tell me if you want to see it.One more thing, an old computer mouse until I get my new microcontroller, and a servo. I started my stripping the mouse down, until nothing but the main components were left. Then I stripped the actual button of its casing so it was just a little copper plate. After that, I mounted the servo to the mouse with a cross connector on the servo, so when the servo was activated, it would push the button. Then I wireed everything up to the board, plugged the secondary mouse into the computer, uploaded the code, and was ready to go! I am using Yahoo as my mail default seeming they let you send texts. I entered in a message I wanted to see when an intruder enters, and tested it. It worked! Anyways, thats it. For now. I will make it wireless when I get my new microcontroller in a few days. And it will be without another computer or mouse, so that will be a plus. I am making a diagram of the circut, so i will post it soon, so you peoples can understand it a little better. Thanks for reading!
