This project using the NCS with openvino and ServoBlaster to drive multiple servos via the GPIO pins to face tracking

• Python 3.5
• Picamera
• OpenVINO
• Numpy
• OpenCV

• A raspberry pi 3B
• A Intel® Neural Compute Stick - (NCS1/2)
• A pan/tilt bracket - (3D printer)
• Two Servos - (SG90)
• A GPIO expansion board
• Pi Camera or USB Webcam

Pan-and-tilt bracket - (3D printer)

[GPIO 4 -> PanMotor] [GPIO 17 -> TiltMotor]

The code defaults to driving 8 servos, the control signals of which should be connected to P1 header pins as follows:

Servo number GPIO number Pin in P1 header Pan-Tilt Motor
 0 4 P1-7 Pan-Motor
 1 17 P1-11 Tilt-Motor
 2 18 P1-12
 3 21/27 P1-13
 4 22 P1-15
 5 23 P1-16
 6 24 P1-18
 7 25 P1-22
