Simple home automation with Android and Arduino

Now and again a neat and simple home automation system is documented, and the latest example is by Instructables member ascas who has created a simple method of controlling up to eight mains power outlets via Bluetooth and an Android device.

An Arduino and Bluetooth module listen for serial commands from the Android device, and then control a bank of relays which take care of switching the mains current. And thanks to the ease of Android app development, Angelo has provided a neat switching app for the user interface.

As always we have to say, mains wiring can be fatal if handled incorrectly so get a licensed electrician, otherwise check out the Instructable to learn more about the project. And for more, we're on facebook, twitter and Google+, so follow us for news and product updates as well. 

If you're looking for a simple way to control many relays from your Arduino, without using up all your digital I/O pins - check out our RELAY8: driver shield:

So what is the RELAY8:? It's an Arduino shield that allows you to drive up to 8 relays from your Arduino using just 2 I/O pins with this shield. It communicates with your board using I2C, so you can even stack several shields together to drive 16, 24, or more outputs! Includes back-EMF protection and works with a wide range of relays. Perfect for home automation projects! For more information and to order, click here
