ITS ALMOST DONE GUYS

I mean not really, but the only problem rn is accuracy. The concept, the software, everything is done, whats left is making it accurate.
Like right now it isnt smart enough to differentiate between a hand and an arm and a whole body.

This will not be a 2d projection using width and height, its kind of a radar right now. It uses length and width. I really dont know how to do the height one, its too confusing.

Also, this project may not work on every laptop, so ill make a video as my submission, since ig its also a hardware project? since it uses speakers?
