HackerBox #0024: Vision Quest
I'll put any of my custom or modified code here.
Pan & Tilt Face Tracking
SerialPanTilt is a basic Arduino sketch for controlling the pan and tilt servos over the serial port.
PanTiltFaceTracker is the code to use in Processing that uses OpenCV for face tracking and sends commands through the serial port to the Arduino. It attempts to keep the first face in the middle of the screen.
