Taking voice input from raspberry pi and sending converted text to arduino to turn on relays I have one raspberry pi B+ and an Arduino uno. I know how to control a relay from an Arduino. I searched a tutorial about voice recognition on arduino but got to know that arduino cannot take in audio inputs. It can just sense if there is an audio. Now I think that I can use the raspberry pi to take inputs and convert it to text with software and then send it to arduino. Then Arduino can control the relay. Is there any way to do that?
Probably the easiest way would be to set up a serial link between them, although there are many ways it could be done; This link looks helpful, as both boards have serial capability, or USB with Pi as host &amp; Arduino as slave should work perfectly well (but a more expensive bit of wire).

An alternative might be an Arduberry?

On the Pi side, there is a sort of meta-answer here - obviously, the Raspberry Pi stackexchange would be the better forum to look at that half of the project.
