Face and Movement Tracking Pan-Tilt System with Raspberry Pi and OpenCV

Hi Tim,

Thanks so much, it was due to not running the older version and it all works now.

I have two more questions about the code:
How can i set the camera to just stay on one person? i.e if there were multiple people in view of the camera.
Can i set the neopixel totally off and then all the pixels come on in a certain colour? when a person is detected.

Sorry for all the questions but im getting more involved with this project each day :smile:
