Many folks use their smartwatch to keep up with their messages and even track their daily activity. Wouldn’t it be nice if you could unlock your door using an Android Wear smartwatch? The Sesame app can help. Developed by Dheera Venkatraman, the app lets you unlock your door by saying “OK Google, Open Sesame” to your Android Wear smartwatch.
The developer used an Arduino Uno, HC-05 Bluetooth module, and HS-311 servo to pull this off. He has also shared useful code on his site to give you an idea how this works. What do you think? Are you impressed?
