Instructables user ASCAS shows off how to add voice control to your Arduino projects using your Android phone and Bluetooth. The Arduino gets a Bluetooth attachment and a set of code.

The Arduino code tells us that the valves will be opened as long as the remote up/down channel is above/under given values.

A perl script running on the iPhone will then send the command to the Arduino. When it receives the start command, the Arduino will ground the wire to the remote start and fire up the car.

Randy Sarafan, who also happens to be the Technology Editor over on Instructables, gutted a remote-controlled car and swapped the parts for an Arduino board.

Want to dive deeper into IR? Maybe this primer on cloning IR remotes with an Arduino will help. And for another project where VB shines, check out this voice controlled RGB LED lamp.
