Recently Gesture controlled Laptops or computers are getting very famous. This technique is called Leap motion which enables us to control certain functions on our computer/Laptop by simply waving our hand in front of it. It is very cool and fun to do it, but these laptops are really priced very high. So in this project let us try building our own Gesture control Laptop/Computer by combining the Power of Arduino and Python . We will use two Ultrasonic sensors to determine the position of our hand and control a media player (VLC) based on the position . I have used this for demonstration, but once you have understood the project, you can do anything by just changing few lines of code and control your favorite application in your favorite way. Pre-requisites: We have already covered few projects which combines Arduino with Python. So I assume that you have already installed Python and its serial library and have successfully tried out...
