This project builds a door unlock system with a different concept. It constructs an ultrasonic distance detector which is used to enter code with hand positions. No readings are taken when hand is not moving, meaning that it is at a minimum distance from the door. This is implemented using an Arduino to calculate standard deviations and applying moving average filter technique. Watch the video for more info.
