Client for echomaster - control PC's sound volume with simple gestures.
This program is designed to work with raspberry pi with server software on it. RPi must have an ultrasonic distance sensor connected via GPIO. By moving hand closer or further from ultrasonic sensor you can change sound volume on all devices(Windows only) connected to that echomaster server.
