“OK Google, open sesame.”
MIT grad Dheera Venkatraman has developed a new way for users to wirelessly unlock their doors with simple Google Now-like commands.
The Maker had created a Google Now app that lets those with an Android Wear on their wrist utter the words “OK Google, Open Sesame” to open a door. Of course, the door itself needs a few “simple yet trivial” modifications in order to make it smartwatch-compatible.
To bring the idea to life, Venkatramann rigged his door with an Arduino Uno (ATmega328), an HC-05 Bluetooth module and a servo, which allows the lock to be activated via its accompanying “barebones” app. The servo is attached to the door latch. Meanwhile, the HC-05 awaits a trigger signal and communicates with the Arduino to actuate the servo to open the door.
