I made a face tracking turret. The main challenge was mapping the angles perfectly so that it actually tracks your face. I installed the openCV dependency and used the pre-trained haarcascade to track my face and a python script which calculates the exact coordinates which are further sent to the arduino to actually control the servos
I made a Face tracking turret which uses python to calculate the coordinate of your face on the camera and send it to an Arduino to control servo motors and move them accordingly.
