Hello all i have created a program which detects and recognizes the faces of the users it is still buggy, but it partially works it has a database which matches with the users photo pulled from the webcam, now i want to, connect Arduino with this program so when a face is recognized a pulse or data is sent to Arduino and a specific action is performed (i.e a motor will rotate, blink a LED, or unlock a door), how can this be done. Thanks.
