It's no secret that you can create an remote-controlled Arduino-based device using an Android smartphone - as creating your own Android apps that can comminucate via Bluetooth is free and not difficult at all. With this in mind, Instructables user taifur has created a practical example that can be reproduced easily.
This example is a password-controlled electric door control - allowing the door to be locked or unlocked via a password entered into a nearby Android device. Of course you can complete other tasks - anything that can be controlled by an Arduino can be controlled using this system - which is demonstrated in the following video:
An excellent framework for a smartphone-controlled device, of which you can learn more from the project's Instructable page. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
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 the 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.
