Hey thanks for taking a look at my post i want to ask a few questions about if my ideas are possible I want to be able to open and shut my garage door from a cell phone i have no knowledge on the GSM shield can i program the Arduino to output voltage from a pin if it receives a text e.g open,close and also send a text to the cell # if there is some thing blocking the door from the sensors pre installed on the door example if there is something in the way send 5v to the arduino and lets say analogue pin 3 is receiving 5 volts send text"door is blocked" thanks guys if you have any questions because i did not provide enough info just ask thanks again - jordyn
Hi
My Arduino application at http://www.2wg.co.nz started life as a garage door opener but I use the internet for the user interface and communications.
I use my iPhone as my garage door opener. A home page link opens the required web page and I just push the OPEN button.
The full source code and documentation for my system is available on the application website.
Cheers
