Gone are the days of fumbling with your keys! Adham Negm has come up with a way to open your door with a simple hand gesture while holding your smartphone.
To accomplish this, Negm uses an Arduino Uno, a servo motor to move the bolt, and a 1Sheeld to interface with the smartphone. The 1Sheeld reads the device’s accelerometer data, and then activates the servo when it recognizes a predefined gesture.
Sound like a hack you’d like to try for your room? You can find the entire project on Instructables.
