Voice Control Garage Door using Raspberry Pi

What a convenience it would be if you can open up your garage door with your smart phone by voice command. A designer named Christopher has done just like that by linking his Android phone and his raspberry pi.

He goes further by installing fail safe proximity switch to determine if the door is already open or closed to prevent misfiring.He further added another protection for his design by  the installation of opto-isolators to protect the circuit from external electricity coming from lightning and short circuit.
