this project have two parts:

first part is a python code that runs on the computer.
and second part is hardware, including Arduino board and 3 servo motors.

in python code with the help of opencv and mediapipe we can trace finger motions and based on finger motions we send commands to arduino board with serial port and Arduino controls servo motors.

For running the python code you need PyCharm software
before running the code you should install:

OpenCV (Open Source Computer Vision Library) is an open source computer vision and machine learning software library.
OpenCV was built to provide a common infrastructure for computer vision applications and to accelerate the use of machine perception in the commercial products.

MediaPipe offers open source cross-platform, customizable ML solutions for live and streaming media. 

You can download the code from the YouTube video description.
