Add voice-control to your Arduino with an Android device

Adding voice-control to an Arduino-based project isn't that new, and can be done with some expensive shields that utilise external voice processors. However many of us may have access to an older Android device that is unused - which can now have a second life thanks to a new app called "Blue Act".

Blue Act is a voice-interpreter app that can convert your voice commands to text which is then sent via Bluetooth or directly through USB via an OTG cable between the Android device and the Arduino. Then it's a simple matter of having the Ardiuno sketch monitor for the required text commands incoming from serial and then taking action. The app runs on Android v3.1 or greater which makes the choice of device to use easy, and it does work - as shown in the following video:

At the time of writing the app is free, so without too much effort you can test it yourself. You can get started from the project demonstration page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

To reproduce the system above with a wireless Bluetooth link you can use 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.
