So you already have an Android Wear watch that you use to keep up with your notifications and track your fitness? Wouldn’t it be nice if you could unlock your doors with it? Sesame, developed by Dheera Venkatraman, is an app that lets you open your door by saying “OK Google, Open Sesame” to your Android Wear smartwatch. He used an Arduino Uno, a HC-05 Bluetooth module, and a HS-311 servo for this project.
You can find useful code snippets and additional information about this project on Sesame’s webpage.
