Face recognition, TTS and Arduino

Faces are recognised and count it up, depending of the presence/absence of faces, a LED is switch on or off using Arduino and a different text to speech is activated indicating presence or absence of faces on the screen. In case of one or more faces present it is automatically said the number of faces and their x and y position on the screen

In this other video the number of LED on is the same as number of faces detected on the screen and it makes photo frames, in this example, only if 3 faces are present.
