Although garage doors can be controlled with the typical wireless solution, more secure and controlled versions can be made with Bluetooth and also be controlled from a popular smartphone. The benefit of using this method is you don't need the manufacturer's remote control as the smartphone app can just be loaded on a new device.
Doing so has been documented by Instructables member arc20052000 who has build a two-channel remote relay solution with Arduino and Bluetooth. The remote control app has been written in Java however you could also create your own using the free Android MIT app inventor environment.
As part of the Arduino and Bluetooth experience you'll need a Bluetooth device for your Arduino projects, and to meet this need we've released our new Freetronics Bluetooth Shield:
We've made it simple to use - the Bluetooth Shield acts as a serial link between the other Bluetooth device. Furthermore there's a wide range of jumpers allowing you to select which digital pins to use for data transfer, increasing compatibility with other shields. And with our Quick Start guide it's easier than ever.
Our Bluetooth Shield for Arduino is now in stock and ready to ship, so for more information and to order - visit the shield's product page.
